Human Evolution provides a comprehensive overview of hominid evolution, synthesising data and approaches from fields as diverse as physical anthropology, evolutionary biology, molecular biology, genetics, archaeology, psychology and philosophy. The book starts with chapters on evolution, population genetics, systematics, and the methods for constructing evolutionary trees. These are followed by a comprehensive review of the fossil history of human evolution since our divergence from the apes. Subsequent chapters cover more recent data, both fossil (...) and molecular, relating to the evolution of modern humans. A final section describes the evolution of culture, language, art, and morality.The authors are leading experts in two complementary fields of scholarship, physical anthropology and molecular evolution. Throughout the book they successfully integrate their expertise in evolutionary theory, phylogenetics, genomics, cultural evolution, language, aesthetics and morality to produce a cutting edge textbook, copiously illustrated and with an extensive and up-to-date bibliography. It will be suitable for both senior undergraduate and graduate level students taking courses on human evolution within departments of biology, anthropology, psychology and philosophy. The book will also appeal to a more general audience seeking a readable, up-to-date and inclusive treatment of human origins and evolution. (shrink)

What does human evolutionary theory reveal about the origins of human nature and the constraints it imposes on human cognition, behavior, and society? “The whole field of human evolution is pregnant with philosophical questions of great interest”, Michael Ruse concludes in the final passage of The Philosophy of Human Evolution. This engaging and eminently readable romp through the philosophical landscape of human evolution fills a significant niche in the existing literature. (...) There are numerous scientific texts surveying historical and contemporary problems in the field of human evolution, and there are many philosophical texts exploring conceptual and methodological problems in evolutionary theory. Ruse interweaves scientific and philosophical work on human evolution with the latest work in biological theory to produce a unique and timely book, one that addresses a range of important topics that rarely find their way into works of this genre. With a relentless lucidity and charming, f .. (shrink)

Initiated by Robert Wesson, _Evolution and Human Values_ is a collection of newly written essays designed to bring interdisciplinary insight to that area of thought where human evolution intersects with human values. The disciplines brought to bear on the subject are diverse - philosophy, psychiatry, behavioral science, biology, anthropology, psychology, biochemistry, and sociology. Yet, as organized by co-editor Patricia A. Williams, the volume falls coherently into three related sections. Entitled Evolutionary Ethics, the first section brings (...) contemporary research to an area first explored by Herbert Spencer. Evolutionary ethics looks to the theory of evolution by natural selection to find values for human living. The second section, Evolved Ethics, discusses the evolution of language and religion and their impact on moral thought and feeling. Evolved ethics was partly Charles Darwin's subject in _The Descent of Man._ The last section bears the title Scientific Ethics. A nascent field, scientific ethics asks about the evolution of human nature and the implications of that nature for ethical theory and social policy. Together, the essays collected here provide important contemporary insights into what it is - and what it may be - to be human. (shrink)

I argue that meaning is a result of our biological evolution, and that language evolved from primates’ ability to grasp conceptually the most important features of their environment. I hold that natural selection and adaptation ensure that primates both sense and conceptualize their world similarly, and that they therefore think similarly, whenever they receive the same sense impressions. This cognitive similarity enabled our predecessors to learn and develop a language because of the regular association of a particular sound and (...) a particular image. The evolutionary pressure on our predecessors to develop a language was the advantage that such a language had for cooperation and survival. Finally, I argue that the old, but in wider circles frowned-upon theory of meaning, the expressive theory of language, provides the best explanation of the relationship between thought, meaning, and words, because it operates with words and not sentences as the basic semantic unit.

The need to create art is found in every human society, manifest in many different ways across many different cultures. Is this universal need rooted in our evolutionary past? The Art Instinct reveals that it is, combining evolutionary psychology with aesthetics to shed new light on fascinating questions about the nature of art.

The critical narrative of this interdisciplinary book offers a first-time look at the interrelationship between biology, mythology and philosophy in human development. Its daring premise follows the trajectory of human thought, starting with the biological roots of fear and the original need for religion, truth-seeking, and myth-making. The narrative then innovatively links a number of maverick philosophical teachings over the centuries, from pre-Buddhist times to the Buddha, from Epicurus and Pyrrho to Lucretius, and eventually to the seminal (...) poetry of Omar Khayyam. These emergent philosophies exemplified liberation from the grasp of mythical and religious thinking and instead espoused an empirical and joyful mind. The narrative concludes with a look at the emancipating philosophical movement that resulted in the European Enlightenment, and it suggests that the philosophical teachings explored in the book may offer the potential for a second, broader Enlightenment.

There is a tendency in both scientific and humanistic disciplines to think of biological evolution in humans as significantly impeded if not completely overwhelmed by the robust cultural and technological capabilities of the species. The aim of this article is to make sense of and evaluate this claim. In Section 2 , I flesh out the argument that humans are ‘insulated’ from ordinary evolutionary mechanisms in terms of our contemporary biological understandings of phenotypic plasticity, niche construction, and cultural transmission. (...) In Section 3 , I consider two obvious objections to the above argument based on the growing literatures related to gene-culture coevolution and recent positive selection on the human genome, as well as a pair of less common objections relating to the connection between plasticity, population size and evolvability. In Section 4 , I argue that both the ‘human evolutionary stasis argument’ and its various detractor theories are premised on a fundamental conceptual flaw: they take evolutionary stasis for granted, since they fail to conceive of stabilizing selection as a type of evolution and drift as a universal tendency that dominates in the absence of selection. Without the continued operation of natural selection, the very properties that are purported to reduce the evolutionary response to selection in humans would themselves drift into non-functionality. I conclude that properly conceived, biological evolution is a permanent and ineradicable fixture of any species, including Homo sapiens. (shrink)

This essay reviews Iain Morley’s The Prehistory of Music, an up-to-date and authoritative overview of recent research on evolution and cognition of musicality from an interdisciplinary viewpoint. Given the diversity of the project explored, integration of evidence from multiple fields is particularly pressing, required for any novel evolutionary account to be persuasive, and for the project’s continued progress. Moreover, Morley convincingly demonstrates that there is much more to understanding musicality than is supposed by some theorists. I outline Morley’s review (...) of the archaeological and ethnographic literature, and then go on to critique his assessment of philosophical and evolutionary theories, offering some alternative perspectives that might better benefit his project.

The need to produce human beings developed in all respects is today generally recognized. But one cannot say that the very notion of "comprehensive development" has been made sufficiently clear in terms of theory. The relationship between such development and education also remains unclear in many respects. Yet the success of the further evolution of our schools and of bringing education in school into accord with the needs of today, and even more of tomorrow, depends on the solution (...) of these problems.

According to anthropological philosopher René Girard, an important human adaptation is our propensity to victimize or scapegoat. He argued that other traits upon which human sociality depends would have destabilized primate dominance-based social hierarchies, making conspecific conflict a limiting factor in hominin evolution. He surmised that a novel mechanism for inhibiting intragroup conflict must have emerged contemporaneously with our social traits, and speculated that this was the tendency to spontaneously unite around the victimization of single individuals. He (...) described an unconscious tendency to both ascribe blame and to imbue the accused with a sacred mystique. This emotionally cathartic scapegoat mechanism, he claimed, enhanced social cohesion, and was the origin of religion, mythology, sacrifice, ritual, cultural institutions, and social norms. It would have functioned by modifying the beliefs and behaviors of the group, rather than of the accused, making the act of accusation more important than the substance. This article aims to examine the empirical evidence for Girard’s claims, and argues that the scapegoat hypothesis has commonalities with several other evolutionary hypotheses, including Wrangham’s execution hypothesis on self-domestication, Dunbar’s hypothesis on the role of storytelling in maintaining group stability, and DeScioli and Kurzban’s hypothesis on the role of non-consequentialist morality in curtailing conflict. Potential implications of the scapegoat hypothesis for evolutionary psychology and psychiatry are discussed. (shrink)

Chimpanzees, but very few other animals, figure prominently in attempts to reconstruct the evolution of uniquely human traits. In particular, the chimpanzee is used to identify traits unique to humans, and thus in need of reconstruction; to initialize the reconstruction, by taking its state to reflect the state of the last common ancestor of humans and chimpanzees; as a baseline against which to test evolutionary hypotheses. Here I point out the flaws in this three-step procedure, and show how (...) they can be overcome by taking advantage of much broader phylogenetic comparisons. More specifically, I explain how such comparisons yield more reliable estimations of ancestral states and how they help to resolve problems of underdetermination inherent to chimpocentric accounts. To illustrate my points, I use a recent chimpocentric argument by Kitcher. (shrink)

This contribution has two main goals which might be labelled for convenience as a pars construens and pars denstruens reversing the usual order of these terms. The first aim is to offer an overview of the main tenets of the book, while the second aim is to raise some critical concerns while remaining sympathetic to the author’s overall project. With regard to the first point, I present the context of intellectual debate where Buchanan’s contribution fits comfortably: Darwin’s evolutionary theory, anthropology, (...) psychology, moral analysis etc. The target here is to show the internal complexity and different layers of analysis of the book. These initial reconstructions are, next, used to formulate some thoughts on what I consider possible problematic points in need of clarification. In particular, first, I hold that Buchanan presents too narrow oppositional views between intergroup relations whereupon the notion of “tribalism” is constructed. Such strong identitarian conception does not seem to depict adequately the sociological dynamics of intergroup relations. Second, I consider the terms in which it can be addressed the notion of the rise of the moral mind in evolutionary terms. The suggestion is to consider in a milder form the author’s key concept of a “Great Uncoupling” for the moral reason. (shrink)

Psychological evidence suggests that laypeople understand the world around them in terms of intuitive ontologies which describe broad categories of objects in the world, such as ‘person’, ‘artefact’ and ‘animal’. However, because intuitive ontologies are the result of natural selection, they only need to be adaptive; this does not guarantee that the knowledge they provide is a genuine reflection of causal mechanisms in the world. As a result, science has parted ways with intuitive ontologies. Nevertheless, since the brain is evolved (...) to understand objects in the world according to these categories, we can expect that they continue to play a role in scientific understanding. Taking the case of human evolution, we explore relationships between intuitive ontological and scientific understanding. We show that intuitive ontologies not only shape intuitions on human evolution, but also guide the direction and topics of interest in its research programmes. Elucidating the relationships between intuitive ontologies and science may help us gain a clearer insight into scientific understanding. (shrink)

Science undermines the certitude of non‐naturalistic answers to the question of whether human life has meaning. I explore whether evolution can provide a naturalistic basis for existential meaning. Using the work of philosopher Daniel Dennett and scientist Ursula Goodenough, I argue that evolution is the locus of the possibility of meaning because it has produced intentionality, the matrix of consciousness. I conclude that the question of the meaning of human life is an existentialist one: existential meaning (...) is a product of the individual and collective tasks human beings undertake. (shrink)

Brain size has increased threefold during the course of human evolution, whilst body weight has approximately doubled. These increases in brain and body size suggest that reproductive rates must have slowed considerably during this period. During the same period, however, environmental heterogeneity has increased substantially. A central tenet of life-history theory states that in heterogeneous environments, organisms with fast life histories will be favoured. The human lineage, therefore, has proceeded in direct contradiction of this theory. This contribution (...) attempts to resolve this contradiction by recourse to Godfrey-Smith’s Environmental Complexity Thesis, which states that the function of cognition is to enable the organism to deal with environmental complexity. It is suggested that among slowly reproducing organisms the behavioural flexibility provided by advanced cognitive abilities is a fundamental component of adaptation to heterogeneous environments. In the human lineage this flexibility is manifest particularly in the increasing complexity of material culture. (shrink)

Are humans a domesticated species? How is this issue related to debates on the roles of human agency in human evolution? This article discusses four views on human domestication: Darwin’s view; the view of those who link human domestication to anthropogenic niche construction and, more specifically, to sedentism; the view of those who link human domestication to selection against aggression and the domestication syndrome; and a novel view according to which human domestication can (...) be conceived of in terms of a process of political selection. The article examines and compares these views to illustrate how discussions of human domestication can contribute to debates about how, and to what extent, human agency has affected human evolution.

The concept of preadaptation, though useful, continues to trouble evolutionary scientists. Usually, it is treated as if it were really adaptation, prompting such diverse theorists as Gould and Vrba, and Dennett to suggest its removal from evolutionary theory altogether. In this paper, I argue that the as-if sense is ill-founded, and that the sense of preadaptation as a process may be defended as unequivocal and generally useful in evolutionary explanations, even in such problem areas as human evolution.

Despite remarkable empirical and methodological advances, our theoretical understanding of the evolutionary processes that made us human remains fragmented and contentious. Here, we make the radical proposition that the cultural communities within which Homo emerged may be understood as a novel exotic form of organism. The argument begins from a deep congruence between robust features of Pan community life cycles and protocell models of the origins of life. We argue that if a cultural tradition, meeting certain requirements, arises in (...) the context of such a “social protocell,” the outcome will be an evolutionary transition in individuality whereby traditions and hominins coalesce into a macroscopic bio-socio-technical system, with an organismal organization that is culturally inherited through irreversible fission events on the community level. We refer to the resulting hypothetical evolutionary individual as a “sociont.” The social protocell provides a preadapted source of alignment of fitness interests that addresses a number of open questions about the origins of shared adaptive cultural organization, and the derived genetic adaptations that support them. Also, social cooperation between hominins is no longer in exclusive focus since cooperation among traditions becomes salient in this model. This provides novel avenues for explanation. We go on to hypothesize that the fate of the hominin in such a setting would be mutualistic coadaptation into a part-whole relation with the sociont, and we propose that the unusual suite of derived features in Homo is consistent with this hypothesis.

Human by Design invites you on a journey beyond Darwin's theory of evolution, beginning with the fact that we exist as we do, even more empowered, and more connected with ourselves and the world, than scientists have believed possible. In one of the great ironies of the modern world, the science that was expected to solve life's mysteries has done just the opposite. New discoveries have led to more unanswered questions, created deeper mysteries, and brought us to the (...) brink of forbidden territory when it comes to explaining our origin and existence. These discoveries reveal the following facts: Fact 1. Our origin--Modern humans appeared suddenly on earth approximately 200,000 years ago, with the advanced brain, nervous system, and capabilities that set them apart from all other known forms of life already developed, rather than having developed slowly and gradually over a long periods of time. Fact 2. Missing physical evidence--The relationships shown on the conventional tree of human evolution are speculative connections only. While they are believed to exist, a 150-year search has failed to produce the physical evidence that confirms the relationships shown on the evolutionary family tree. Fact 3. New DNA evidence--The comparison of DNA between ancient Neanderthals, previously thought to be our ancestors, and early humans tells us thatwe did not descend from the Neanderthals. Fact 4. A rare DNA fusion--Advanced genome analysis reveals that the DNA that sets us apart from other primates, including in our advanced brain and nervous system, is the result of an ancient and precise fusion of genes occurring in a way that suggests somethingbeyondevolution made our humanness possible. Fact 5. Our extraordinary abilities--We are born with the capacity to self-heal, to self-regulate longevity, to activate an enhanced immune response, and to experience deep intuition, sympathy, empathy, and, ultimately, compassion--and to do each of these on demand. In this book, New York Timesbest-selling author and 2017 Templeton Award nominee Gregg Braden crosses the traditional boundaries of science and spirituality to answer the timeless question at the core of our existence--Who are we?--and to reveal science-based techniques that awaken our uniquely human experiences of deep intuition, precognition, advanced states of self-healing, and much more! Beyond any reasonable doubt, Human by Design reveals that we're not what we've been told, and much more than we've ever imagined. (shrink)

The current spread of coronavirus has caught our modern world by surprise, which leads to widespread panic, fear and confusion. However, if we view the unfolding of these events from a scientific historical perspective of past human evolution, we may discover the reoccurring patterns of the environmental conditions that give rise to such epidemics. Hence, we can figure out better methods to prepare and react to the infectious agents that spread diseases that have shaped the course of (...) class='Hi'>human history before. Here, I propose a holistic view of human evolution, with an interdisciplinary approach that studies how cyclic variation in solar UV energy affects the evolution of viruses and shapes the symbiotic dynamics of human life on earth.

From the time that they diverged from their common ancestor, chimpanzees and humans have had a very different evolutionary path. It seems obvious that the appearance of culture and technology has increasingly alienated humans from the path of natural selection that has informed chimpanzee evolution. According to philosopher Peter Sloterdijk any type of technology is bound to have genetic effects. But to what extent do genomic comparisons provide evidence for such an impact of ‘anthropotechnology’ on our biological evolution?

The theory of evolution settled at what was thought to be its definitive form after the affiliation of Darwin’s theory with the new science of genetics. This historical event explains not only the success but also the vulnerability of evolutionary theory. The close affinity with genetics helped to provide the tools required for managing phylogenetic evolution, which was controlled by the molecular machinery of the genome, localized in most cells of each individual. This setup worked well for organizing (...) the basics of Darwinism but it faltered when applied to the evolution of culture. This is so because, as I argue in this article, under the given conditions the active support of a system of similar complexity as the genome would be required. At some point in the process of evolution the large brains of primates may have begun experimenting with phenotypic equivalents of genomic functions like memory, adaptation, fitness, processing information, and organizing replication. In this way the brain may have weakened its ties to the genome and by exploiting its new status have become, so to speak, for the phenotype what the genome is for the genotype, thus preparing the stage on which the complexity of human behavior might unfold.
