In this paper, I give an account of how our hominin ancestors evolved a conscious ability I call scenario visualization that enabled them to manufacture novel tools so as to survive and flourish in the ever-changing and complex environments in which they lived. I first present the ideas and arguments put forward by evolutionary psychologists that the mind evolved certain mental capacities as adaptive responses to environmental pressures. Specifically, Steven Mithen thinks that the mind has evolved cognitive fluidity, viz., (...) an ability to exchange information flexibly between and among mental modules. Showing the deficiency in Mithen’s view, I then argue that the flexible exchange of information between and among modules together with scenario visualization is what explains the ability to construct the novel tools needed to survive and flourish in the environments in which our hominin ancestors resided. Finally, I trace the development of the multi-purposed javelin, from its meager beginnings as a stick, in order to illustrate scenario visualization in novel tool manufacturing. (shrink)

Biologists having rediscovered amphioxus, also known as the lancelet or Branchiostoma, it is time to reassess its place in early Darwinist debates over vertebrate origins. While the advent of the ascidian–amphioxus theory and challenges from various competitors have been documented, this article offers a richer account of the public appeal of amphioxus as a primitive ancestor. The focus is on how the ‘German Darwin’ Ernst Haeckel persuaded general magazine and newspaper readers to revere this “flesh of our flesh and blood (...) of our blood”, and especially on Das neue Laienbrevier des Haeckelismus (The new lay breviary of Haeckelism) by Moritz Reymond with cartoons by Fritz Steub. From the late 1870s these successful little books of verse introduced the Neapolitan discoveries that made the animal’s name and satirized Haeckel’s rise as high priest of its cult. One song is reproduced and translated here, with a contemporary “imitation” by the Canadian palaeontologist Edward John Chapman, and extracts from others. Predating the American “It’s a long way from amphioxus” by decades, these rhymes dramatize neglected ‘species politics’ of Darwinism and highlight the roles of humour in negotiating evolution.

This article argues that social selection pressures in recent human evolution were primarily responsible for the emergence of modern cognition. These selection pressures took three specific forms: Increased security and stability, which reduced allostatic load on developing children, facilitating expanded working memory development; increased opportunities for mother-infant joint engagement, which created positive selection for more sophisticated forms of cognition; and increased pressure on ritualized behavior associated with both mother-infant joint engagement and the construction and maintenance of an unprecedentedly complex adult (...) social world. These pressures directly affected the development of the behavioral trait of effortful control in children. Effortful control is closely linked with executive functions, including working memory. Effortful control also shows characteristics that make it a prime candidate for rapidly spreading, culturally driven changes that were prevalent late in human evolution. (shrink)

The renowned biologist and thinker Richard Dawkins presents his most expansive work yet: a comprehensive look at evolution, ranging from the latest developments in the field to his own provocative views. Loosely based on the form of Chaucer's Canterbury Tales, Dawkins's Tale takes us modern humans back through four billion years of life on our planet. As the pilgrimage progresses, we join with other organisms at the forty "rendezvous points" where we find a common ancestor. The band of pilgrims swells (...) into a vast crowd as we join first with other primates, then with other mammals, and so on back to the first primordial organism. Dawkins's brilliant, inventive approach allows us to view the connections between ourselves and all other life in a bracingly novel way. It also lets him shed bright new light on the most compelling aspects of evolutionary history and theory: sexual selection, speciation, convergent evolution, extinction, genetics, plate tectonics, geographical dispersal, and more. The Ancestor's Tale is at once a far-reaching survey of the latest, best thinking on biology and a fascinating history of life on Earth. Here Dawkins shows us how remarkable we are, how astonishing our history, and how intimate our relationship with the rest of the living world. (shrink)

Our understanding of what microbes are and how they evolve has undergone many radical shifts since the late nineteenth century, when many still believed that bacteria could be spontaneously generated and most thought microbial “species” (if any) to be unstable and interchangeable in form and function (pleomorphic). By the late twentieth century, an ontology based on single cells and definable species with predictable properties, evolving like species of animals or plants, was widely accepted. Now, however, genomic and metagenomic data (...) show that lateral gene transfer compromises this picture of stability and predictability, and refocuses our attention on multilineage communities. Treating such communities as unstable but identifiable evolving “individuals” makes us again pleomorphists, of a sort. (shrink)

: Despite its amazing morphological diversity, life as we know it on Earth today is remarkably similar in its basic molecular architecture and biochemistry. The assumption that all life on Earth today shares these molecular and biochemical features is part of the paradigm of modern biology. This paper examines the possibility that this assumption is false, more specifically, that the contemporary Earth contains as yet unrecognized alternative forms of microbial life. The possibility that more than one form of life (...) arose on Earth is consistent with our current understanding of conditions on the early Earth and the biochemical and molecular possibilities for life. Arguments that microbial descendents of an alternative origin of life could not co-exist with familiar life are belied by what we know of the complexity and diversity of microbial communities. Furthermore, the tools that are currently used to explore the microbial world – microscopy (with the aid of techniques such as DAPI staining and fluorescence in situ hybridization), cultivation and PCR amplification of rRNA genes – could not detect such organisms if they existed. Thus, the fact that we have not discovered any alternative life forms cannot be taken as evidence that they do not exist. (shrink)

The first promising results from “streamlined,” minimal genomes tend to support the notion that these are a useful tool in biological systems engineering. However, compared with the speed with which genomic microbial sequencing has provided us with a wealth of data to study biological functions, it is a slow process. So far only a few projects have emerged whose synthetic ambition even remotely matches our analytic capabilities. Here, we survey current technologies converging into a future ability to engineer large‐scale (...) biological systems. We argue that the underlying synthetic technology, de novo DNA synthesis, is already rather mature – in particular relative to the scope of our current synthetic ambitions. Furthermore, technologies towards rationalizing the design of the newly synthesized DNA fragment are emerging. These include techniques to implement complex regulatory circuits, suites of parts on a DNA and RNA level to fine tune gene expression, and supporting computational tools. As such DNA fragments will, in most cases, be destined for operating in a cellular context, attention has to be paid to the potential interactions of the host with the functions encoded on the engineered DNA fragment. Here, the need of biological systems engineering to deal with a robust and predictable bacterial host coincides with current scientific efforts to theoretically and experimentally explore minimal bacterial genomes.

While unicellular microbes such as phytoplankton (marine algae) have long been considered immortal unless eaten by predators, recent research suggests that under specific conditions entire populations of phytoplankton actively kill themselves; their assumed atemporality is being revised as marine ecologists recognize phytoplankton’s important role in the global carbon cycle. Drawing on empirical research into programmed cell death in marine microbes, this article explores how, in their study of microbial death, scientists change not only our understanding of microbial temporality, (...) but also reconstruct the relationship between life and death, biological individuality and assumptions about a natural teleology associated with bounded biological systems and genetic programmes. Reading this research together with a Derridean deconstruction of the limit between human and other animals with respect to death, this article explores how the deconstruction of individuality from within biology may suggest alternatives to our anthropocentric notion of time and embodiment.

Amidst the recent threat of COVID-19, home gardens have surged in popularity as seed companies and nurseries find it challenging to keep their supplies fully stocked. The victory garden movement that emerged during WWII has today re-emerged as COVID victory gardens. Yet, the global changes and cognitive shifts associated with COVID-19 have differential impacts. The narrative of COVID victory gardens depoliticizes urban agriculture. It is blind to its long history in marginalized, oppressed, and displaced communities where home gardens have always (...) been part of a struggle for identity, autonomy, and self- and communal-determination. I argue the blindness embedded in the narrative of COVID victory gardens violates our “food-related obligations,” which are our responsibilities to ourselves, our food, and each other. Silencing how communities of color have historically grown food in pursuit of dignity disregards how home gardens in communities of color are not merely a reactionary response to crisis but part of a historical legacy whereby people of color have grown food for generations to create and recreate sustainable ways of living that validate their cultures, knowledges, and ways of being.

Preston Greene (2020) argues that we should not conduct simulation investigations because of the risk that we might be terminated if our world is a simulation designed to research various counterfactuals about the world of the simulators. In response, we propose a sequence of arguments, most of which have the form of an "even if” response to anyone unmoved by our previous arguments. It runs thus: (i) if simulation is possible, then simulators are as likely to care about simulating simulations (...) as they are likely to care about simulating basement (i.e. non-simulated) worlds. But (ii) even if simulations are interested only in simulating basement worlds the discovery that we are in a simulation will have little or no impact on the evolution of ordinary events. But (iii) even if discovering that we are in a simulation impacts the evolution of ordinary events, the effects of seeming to do so could also happen in a basement world, and might be the subject of interesting counterfactuals in the basement world Finally, (iv) there is little reason to think that there is a catastrophic effect from successful simulation probes, and no argument from the precautionary principle can be used to leverage the negligible credence one ought have in this. Thus, if we do develop a simulation probe, then let’s do it. (shrink)

The proposal for reproducing human generations in vitro raises the question to what extent parenthood is possible in embryos and to what extent human rights and interests are dependent on conscious awareness. This paper argues that the interest in not being made a parent non-consensually for the benefit of others persists throughout the lifespan of the individual human organism. We do not become genetic parents by learning that we are parents; rather, we discover (or fail to discover) an existing genetic (...) relationship between our offspring and ourselves. The claim to genetic parenthood of an embryo used for reproduction in vitro is, if anything, clearer than the claim of the adult for whom gametes are derived via ips cells, in that an embryo’s cells, unlike an adult’s somatic cells, are already functionally geared to producing gametes (among other types of cell). An embryo used to make gametes that are used in reproduction is immediately and non-consensually made a genetic parent and to that extent is wronged whether or not the parent embryo survives – as some could survive – the harvesting of cells. All human individuals carry objective interests in benefits appropriate to the kind of being they are; these include the stake in not being made a parent without one’s consent, whether posthumously or otherwise.

Ethical questions about end-of-life treatment present themselves at two levels. In clinical situations, patients, families, and healthcare workers sift through ambivalent feelings and conflicting values as they try to resolve questions in particular circumstances. In a very different way, at the societal level, policy makers, lawyers, and bioethicists attempt to determine the best policies and laws to regulate practices about which there are a variety of deeply held beliefs. In the United States we have tried a number of ways to (...) resolve the societal-level issues. We have ignored them, argued to try to convince others of our beliefs, voted to let the majority determine what is right or wrong, and turned to the courts to decide, as in the cases of Karen Ann Quinlan, Nancy Cruzan, and Jack Kervorkian. Yet none of these approaches has yet left us with comfortable, unambiguous cultural norms about issues such as euthanasia and physician-assisted suicide, which are readily assumed by as they face individual and interpersonal dilemmas.

I propose a T‐cell receptor (TcR)‐based mechanism by which immunity mediates both “genetic self” and “microbial self” thereby, connecting microbiome disease with autoimmunity. The hypothesis is based on simple principles. First, TcR are selected to avoid strong cross‐reactivity with “self,” resulting in selection for a TcR repertoire mimicking “genetic self.” Second, evolution has selected for a “microbial self” that mimics “genetic self” so as to share tolerance. In consequence, our TcR repertoire also mimics microbiome antigenicity, providing a novel (...) mechanism for modulating tolerance to it. Also, the microbiome mimics the TcR repertoire, acting as a secondary immune system. I call this TcR‐microbiome mimicry “holoimmunity” to denote immune tolerance to the “holobiont self.” Logically, microbiome‐host mimicry means that autoimmunity directed at host antigens will also attack components of the microbiome, and conversely, an immunological attack on the microbiome may cross‐react with host antigens producing “holoautoimmunity.”.

The assumption that all life on Earth today shares the same basic molecular architecture and biochemistry is part of the paradigm of modern biology. This paper argues that there is little theoretical or empirical support for this widely held assumption. Scientists know that life could have been at least modestly different at the molecular level and it is clear that alternative molecular building blocks for life were available on the early Earth. If the emergence of life is, like other natural (...) phenomena, highly probable given the right chemical and physical conditions then it seems likely that the early Earth hosted multiple origins of life, some of which produced chemical variations on life as we know it. While these points are often conceded, it is nevertheless maintained that any primitive alternatives to familiar life would have been eliminated long ago, either amalgamated into a single form of life through lateral gene transfer or alternatively out-competed by our putatively more evolutionarily robust form of life. Besides, the argument continues, if such life forms still existed, we surely would have encountered telling signs of them by now. These arguments do not hold up well under close scrutiny. They reflect a host of assumptions that are grounded in our experience with large multicellular organisms and, most importantly, do not apply to microbial forms of life, which cannot be easily studied without the aid of sophisticated technologies. Significantly, the most powerful molecular biology techniques available—polymerase chain reaction amplification of rRNA genes augmented by metagenomic analysis—could not detect such microbes if they existed. Given the profound philosophical and scientific importance that such a discovery would represent, a dedicated search for ‘shadow microbes’ seems in order. The best place to start such a search is with puzzling phenomena, such as desert varnish, that resist classification as ‘biological’ or ‘nonbiological’. (shrink)

Bacteria have developed an impressive ability to survive and propagate in highly diverse and changing environments by evolving phenotypic heterogeneity. Phenotypic heterogeneity ensures that a subpopulation is well prepared for environmental changes. The expression bet hedging is commonly (but often incorrectly) used by molecular biologists to describe any observed phenotypic heterogeneity. In evolutionary biology, however, bet hedging denotes a risk‐spreading strategy displayed by isogenic populations that evolved in unpredictably changing environments. Opposed to other survival strategies, bet hedging evolves because the (...) selection environment changes and favours different phenotypes at different times. Consequently, in bet hedging populations all phenotypes perform differently well at any time, depending on the selection pressures present. Moreover, bet hedging is the only strategy in which temporal variance of offspring numbers per individual is minimized. Our paper aims to provide a guide for the correct use of the term bet hedging in molecular biology. (shrink)

Programmed cell death (PCD) in unicellular organisms is in some instances an altruistic trait. When the beneficiaries are clones or close kin, kin selection theory may be used to explain the evolution of the trait, and when the trait evolves in groups of distantly related individuals, group or multilevel selection theory is invoked. In mixed microbial communities, the benefits are also available to unrelated taxa. But the evolutionary ecology of PCD in communities is poorly understood. Few hypotheses have been (...) offered concerning the community role of PCD despite its far-reaching effects. The hypothesis we consider here is that PCD is a black queen. The Black Queen Hypothesis (BQH) outlines how public goods arising from a leaky function are exploited by other taxa in the community. Black Queen (BQ) traits are essential for community survival, but only some members bear the cost of possessing them, while others lose the trait In addition, BQ traits have been defined in terms of adaptive gene loss, and it is unknown whether this has occurred for PCD. Our conclusion is that PCD fulfils the two most important criteria of a BQ (leakiness and costliness), but that more empirical data are needed for assessing the remaining two criteria. In addition, we hold that for viewing PCD as a BQ, the original BQH needs to include social traits. Thus, despite some empirical and conceptual shortcomings, the BQH provides a helpful avenue for investigating PCD in microbial communities. (shrink)

Biodiversity has become one of the most important conservation values that drive our ecological management and directly inform our environmental policy. This paper highlights the dangers of strategically appropriating concepts from ecological sciences and also of uncritically inserting them into conservation debates as unqualified normative landmarks. Here, I marshal evidence from a cutting-edge research program in microbial ecology, which shows that if species richness is our major normative target, then we are faced with extraordinary ethical implications. This example challenges (...) our well-received beliefs about biodiversity and it invites us to critically rethink the nature of this concept so that a more robust understanding of biodiversity and of its role in conservation policy could emerge.

The purpose of this book is two-fold. First, it provides an anthropological analysis of the transhumanist technological imagination. It explores the visions and values that animate transhumanist initiatives in the contemporary United states, and it explores the various ways transhumanists seek to use science and technology to usher in an enhanced posthuman future. Second, the book uses the study of transhumanism as a way to introduce a new generation of students to the discipline of cultural anthropology. In classic anthropological fashion, (...) it argues that transhumanism can be better understood by approaching it from a comparative perspective. It shows how transhumanist efforts to transform the future of our species speak to a longstanding set of concerns within the discipline of cultural anthropology. (shrink)

How do we BIPOC folx survive amid cavernous terror and soul-ripping trauma? In this heart-centered literary story, I embark on a mystical, womanist narration—autohistoria-teoría—to provide the broken-hearted a pathway to better conceptualize and practice irreparable grief. From the incomprehensible pain of walking through the loss of three of my children as a WoC in the American nation-state, I serve as a mirror to BIPOC folx who sit in loss of any kind, and I demonstrate how to piece back together the (...) wandering fragments of our Soul from shattering grief. In this work, I respond to the paucity of BIPOC-centered (un)birth trauma research by raising the volume on BIPOC reproductive trauma. I urgently step away from the multilayered inadequacies and insufficiencies of “western” psychotherapeutic models of trauma healing that are violent to us BIPOC folx and serve to pathologize our grief, and I dedicate myself to excavating critical Indigenous epistemology. I accomplish this with a deliberate and intentional blend of the personal, spiritual, and the scholarly to uncover the ways in which our narratives as BIPOC folx are often erased within material experiences.

We report evidence further supporting homology between proteins in the F1FO‐ATP synthetase and the bacterial flagellar motor (BFM). BFM proteins FliH, FliI, and FliJ have been hypothesized to be homologous to FO‐b + F1‐δ, F1‐α/β, and F1‐γ, with similar structure and interactions. We conduct a further test by constructing a gene order dataset, examining the order offliH,fliI, andfliJgenes across the phylogenetic breadth of flagellar and nonflagellar type 3 secretion systems, and comparing this to published surveys of gene order in the (...) F1FO‐ATP synthetase, its N‐ATPase relatives, and the bacterial/archaeal V‐ and A‐type ATPases. Strikingly, thefliHIJgene order was deeply conserved, with the few exceptions appearing derived, and exactly matching the widely conserved F‐ATPase gene orderatpFHAG, coding for subunits b‐δ‐α‐γ. The V/A‐type ATPases have a similar conserved gene order. Our results confirm homology between these systems, and suggest a rare case of synteny conserved over billions of years, predating the Last Universal Common Ancestor (LUCA). (shrink)

A masterful paean to the human imagination from a wonderfully elegant thinker, _Out of Our Minds_ shows that bad ideas are often more influential than good ones; that the oldest recoverable thoughts include some of the best; that ideas of Western origin often issued from exchanges with the wider world; and that the pace of innovative thinking is under threat.

This article puts into conversation Friedrich Nietzsche’s perspectivism and a particular expression of “African animism,” drawn from my ethnographic fieldwork in Ghana. Nietzsche’s perspectivism extends interpretation beyond the human species into natural processes. Like perspectivism, African animism troubles the binaries—body/soul, nature/culture—that permeate anthropocentric thinking. Human-nonhuman relations are refigured as socio-ecological relations: the earth may be regarded as life-generating ancestors; baobab trees may approach humans as kin. These two images of the world intersect, but they do not mesh together. Nietzsche (...) adopts perspectivism as active intersections between dynamic processes, within an open universe that has not been predesigned for humans. Animism tends toward a world of personalized relationships that would reach harmony if we would only lighten our ecological footprint. I draw upon such resonances to advance a new ethic of experiential environmentalism that treats ecological threats as lived risks and shared experiences with a lively and communicating “environment.”.

The Dutch microbiologist/biochemist Albert Jan Kluyver was an early proponent of the idea of biochemical unity, and how that concept might be demonstrated through the careful study of microbial life. The fundamental relatedness of living systems is an obvious correlate of the theory of evolution, and modern attempts to construct phylogenetic schemes support this relatedness through comparison of genomes. The approach of Kluyver and his scientific descendants predated the tools of modern molecular biology by decades. Kluyver himself is poorly (...) recognized today, yet his influence at the time was profound. Through lens of today however, it has been argued that the focus by Kluyver and others to create taxonomic and phylogenetic schemes using morphology and biochemistry distorted and hindered progress of the discipline of microbiology, because of a perception that the older approaches focused too much on a reductionist worldview. This essay argues that in contrast the careful characterization of fundamental microbial metabolism and physiology by Kluyver made many of the advances of the latter part of the twentieth century possible, by offering a framework which in many respects anticipated our current view of phylogeny, and by directly and indirectly training a generation of scientists who became leaders in the explosive growth of biotechnology.

We are reliable about logic in the sense that we by-and-large believe logical truths and disbelieve logical falsehoods. Given that logic is an objective subject matter, it is difficult to provide a satisfying explanation of our reliability. This generates a significant epistemological challenge, analogous to the well-known Benacerraf-Field problem for mathematical Platonism. One initially plausible way to answer the challenge is to appeal to evolution by natural selection. The central idea is that being able to correctly deductively reason conferred a (...) heritable survival advantage upon our ancestors. However, there are several arguments that purport to show that evolutionary accounts cannot even in principle explain how it is that we are reliable about logic. In this paper, I address these arguments. I show that there is no general reason to think that evolutionary accounts are incapable of explaining our reliability about logic. (shrink)

Large‐scale characterization of the human microbiota has largely focused on Western adults, yet these populations may be uncharacteristic because of their diets and lifestyles. In particular, the rise of “Western diseases” may in part stem from reduced exposure to, or even loss of, microbes with which humans have coevolved. Here, we review beneficial microbes associated with pathogen resistance, highlighting the emerging role of complex microbial communities in protecting against disease. We discuss ways in which modern lifestyles and practices may (...) deplete physiologically important microbiota, and explore prospects for reintroducing or encouraging the growth of beneficial microbes to promote the restoration of healthy microbial ecosystems.

Myths of origin in archaic culture – including the Hebrew Scriptures – locate reality at the point of origin. The Greek term, αρχη, means both origin and governance. How something originates governs its definition; it was assumed by our ancestors. Hence the term archonic. Until we get to Christian eschatology and the promise of the new creation. In the New Testament, we find that God’s eschatological consummation will retroactively define what has always been. God’s redemption will epigenetically redefine what (...) occurred at our genesis. Who you and I really are as creatures will be determined by our completion in the Kingdom of God. The new creation, Omega, determines what was true at the point of origin, that is, at Alpha.Contribution: This article develops a theology of nature that incorporates natural science and augments the journal series in this subject area. Furthermore, this article develops a retroactive ontology based on the New Testament promise of an eschatological new creation. (shrink)

Microscopy has revealed tremendous diversity of bacterial and eukaryotic forms. Recent molecular analyses show discordance in estimates of biodiversity between morphological and molecular analyses. Moreover, phylogenetic analyses of the diversity of microbial forms reveal evidence of convergence at scales as deep as interdomain: morphologies shared between bacteria and eukaryotes. Here, we highlight examples of such discordance, focusing on exemplary lineages such as testate amoebae, ciliates, and cyanobacteria. These have long histories of morphological study, enabling deeper analyses on both the (...) molecular and morphological sides. We discuss examples in two main categories: (i) morphologically identical (or highly similar) individuals that are genetically distinct and (ii) morphologically distinct individuals that are genetically the same. We argue that hypotheses about discordance can be tested using the concept of neutral morphologies, or more broadly neutral phenotypes, as a null hypothesis. -/- . (shrink)

The first annual Alchemy Lecture brings four deep and agile writers from different geographies and disciplines into vibrant conversation on a topic of urgent relevance: humans and borders. Borders, Human Itineraries, and All Our Relation captures and expands those conversations in insightful, passionate ways. Architect, artist, and urban theorist Dele Adeyemo (UK/Nigeria) calls attention to the complexity of Black infrastructures, questioning how "the environments that surround us condition the possibility of our being." Poet Natalie Diaz (US/Mojave/Akimel O'otham) writes: "Like story, (...) migration is the sensual movement of knowledge," and asks, "What is the language we need to live right now?" Philosopher Nadia Yala Kisukidi (France) suggests there is no diasporic life "without the dynamics of fabulation, where we pass down, from generation to generation, the stories of our ancestors who walked barefoot for many months." And cultural theorist Rinaldo Walcott (Canada) asks us to consider inheritances beyond white supremacist logics: "What might it mean to live a life, if we can't risk desiring and working towards utopia?" As each Alchemist considers the legacies of anticolonial struggle, the future of the planet, and the textures of Black and Indigenous life, their essays speak to each other in multiple ways, creating something startling and revelatory: a vision of the world as it is, and as it could be.

With roots in Greek drama, mimesis has recently undergone expansion into an unexpected domain: microbial resistance to viruses. Research revealed that bacteria copy portions of the DNA of attacking viruses and incorporate them into their own DNA. When a virus attacks again, the bacteria generate matching RNA sequences that, together with the Cas9 protein, enable them to recognize the virus and cut its DNA. This process satisfies the requisites for mimesis, thus justifying the name microbiomimesis. It exemplifies nonconscious cognition, (...) a capacity that all lifeforms possess to process and interpret information in contexts that connect it with meaning. In 2012 Jennifer Doudna and Emmanuelle Carpentier coauthored a paper showing that the bacterial defense of RNA/cas9 can be programmed to work as a gene editing tool. So was born CRISPR-Cas9, a technology now routinely used to edit genes by detecting their precise location and modifying them. Never has mimesis been so controversial and laden with implications for the futures of human and nonhuman lifeforms on the planet; what lessons can its traditions offer? (shrink)

According to the most common interpretation of the simulation argument, we are very likely to live in an ancestor simulation. It is interesting to ask if some families of simulations are more likely than others inside the space of all simulations. We argue that a natural probability measure is given by computational complexity: easier simulations are more likely to be run. Remarkably this allows us to extract experimental predictions from the fact that we live in a simulation. For instance we (...) show that it is very likely that humanity will not achieve interstellar travel and that humanity will not meet other intelligent species in the universe, in turn explaining the Fermi's Paradox. On the opposite side, experimental falsification of any of these predictions would constitute evidence against our reality being a simulation. (shrink)

Food for Thought seeks to enlighten people about their power as individuals to shape industry and society starting from the food they eat. The reader is invited to question who is really benefiting from our present food system through a detailed science-based analysis of food production and consumption. Perussello discusses how the production and consumption of animal products go well beyond the blatant violence against non-human animals: she posits that animal agriculture is procuring a world of disease, unhappiness, injustice, and (...) environmental depletion. Our author then presents an accessible, science-based analysis of animal food production from the perspective of Food Process Engineering. She then provides insightful discussions on the health, ecological, social, and spiritual implications of our diet. This information is supported by powerful photographs taken by Animal Equality's undercover investigators in animal farms worldwide. The author elaborates on the relationship between microbial pathogens (including Covid-19), antibiotic resistance, and the consumption of animal products, rendering Food for Thought a timely reading. The book also unveils myths on "humane" and "sustainable" animal foods, such as organic milk, grass-fed meat, and cage- free eggs, demonstrating how animal agriculture is the antithesis of compassion and sustainability, regardless of farm size, production system, and geographical region. Food for Thought is ultimately an invitation to a regenerated society. This book will help vegetarians and omnivores align their actions with their values and live a happier, more fulfilling life. The unprecedented views on food production offered by this compelling reading will also empower vegans in communicating with their non-vegan peers about the importance of following a plant-based living.
