Stable adaptive strategy of Homo sapiens (SESH) is a superposition of three different adaptive data arrays: biological, socio-cultural and technological modules, based on three independent processes of generation and replication of an adaptive information – genetic, socio-cultural and symbolic transmissions (inheritance). Third component SESH focused equally to the adaptive transformation of the environment and carrier of SESH. With the advent of High Hume technology, risk has reached the existential significance level. The existential level of technical risk is, by definition, an (...) evolutionary risk as possible leads to the genesis of disappearance of humanity as a species. The emergence of bioethics has to consider as a form of modern (transdisciplinary) scientific concept and sociocultural adaptation for regulate human identity in the global-evolutionary transformation and performs the function of self-preservation.

One of the key challenges confronting cognitive science is to discover natural categories of cognitive function. Of special interest is the unity or diversity of cognitive control mechanisms. Evolutionary history is an underutilized resource that, together with neuropsychological and neuroscientific evidence, can help to provide a biological ground for the fractionation of cognitive control. Comparative evidence indicates that primate brain evolution has produced dissociable mechanisms for external action control and internal self-regulation, but that most real-world behaviors rely on a (...) combination of these. The archeological record further indicates the timing and context of distinctively human elaborations to these cognitive control functions, including the gradual emergence of increasingly complex hierarchical action control.

We considered peculiarities of the evolution of a region with sharp boundaries that is filled with a partially ionized plasma and is a part of the volume of a condensed target. The creation of such a region in the near-surface layer of the target can be related to the action of an external impulse symmetric ionizator or to the action of an intense small-extension shock wave on the target surface. We defined the conditions such that their fulfilment during the (...) establishment of the equilibrium between the Coulomb attraction of electrons and ions with atom ionization multiplicity Z* 1 and the kinetic pressure of electrons causes both the compression of this region and its ionization to the state with Z* 2 > Z* 1. The last leads to a further additional compression and ionization. Under these conditions, the spontaneous avalanche-like ionization of atoms of the target to the state of ‘‘bare’’ nuclei occurs synchronously with the avalanche-like metallization and the self-compression of the target. We showed that the avalanche-like ionization and the self-compression of the target happen in the case where the gas of degenerate electrons has drift momentum. If the region with initial ionization has the form of thin spherical layer, the process of avalanche-like ionization and self-compression of the target in this region is accompanied by the accelerated movement of the plasma layer to the target center. One of the reasons for the accelerated movement is the surface tension in a bounded domain of the nonequilibrium plasma layer neutralized by ions of the target. With increase in the velocity of movement of this layer to the target center, the additional self-compression of the system of electrons and nuclei to the state of degenerate electron gas occurs. At the leading edge of the running layer with extremely high electron density which is neutralized by nuclei of the target, the formation of a collapse of the electron--nucleus system proceeds, and the binding energy maximum for the electron--nucleus system shifts from A≈60 to A ≫ 60. This result makes possible the fast synthesis of superheavy nuclei. The decay of the collapse state, a partial restoration of the target structure, its rapid cooling, and the condensation of a part of the products of nuclear reactions happen in the target volume at the trailing edge of the moving plasma layer. Upon such a scanning propagation of the wave with high electron density, all the target substance is involved, step-by-step, to the process of nuclear transformations. At the target center, the moving plasma layer is squeezed with the formation of the state of quasistationary collapse under inertial confinement. Then the collapse state decays irreversibly.

The self-domestication hypothesis suggests that, like mammalian domesticates, humans have gone through a process of selection against aggression – a process that in the case of humans was self-induced. Here, we extend previous proposals and suggest that what underlies human social evolution is selection for socially mediated emotional control and plasticity. In the first part of the paper we highlight general features of human social evolution, which, we argue, is more similar to that of other social mammals than (...) to that of mammalian domesticates and is therefore incompatible with the notion of human self-domestication. In the second part, we discuss the unique aspects of human evolution and propose that emotional control and social motivation in humans evolved during two major, partially overlapping stages. The first stage, which followed the emergence of mimetic communication, the beginnings of musical engagement, and mimesis-related cognition, required socially mediated emotional plasticity and was accompanied by new social emotions. The second stage followed the emergence of language, when individuals began to instruct the imagination of their interlocutors, and to rely even more extensively on emotional plasticity and culturally learned emotional control. This account further illustrates the significant differences between humans and domesticates, thus challenging the notion of human self-domestication. (shrink)

This paper studies a simple dynamical system of stock price fluctuation time series based on the rule of stock market. When the stock price fluctuation system is disturbed by external excitations, the system exhibits obviously chaotic phenomena, and its basic dynamic properties are analyzed. At the same time, a new fixed-time convergence theorem is proposed for achieving fixed-time control of stock price fluctuation system. Finally, the effectiveness of the method is verified by numerical simulation.

Multiplicity and continual change characterize the Peruvian agricultural knowledge and information system (AKIS), reflecting changes in the agricultural sector as a whole. The evolution of these changes can be traced back to the pre-Columbian era when a relatively stable and well-organized system based on indigenous knowledge prevailed. During colonial (1532–1821) and early Republican times (beginning 1821) several changes affecting the agricultural sector contributed to a weakening of indigenous knowledge systems. During the 20th century extension services provided by the government (...) and a variety of private organizations began to play an important role in the dissemination of information, albeit in an erratic way. Since the 1970s the system increased in complexity with the emergence of non-governmental institutions. Today government participation is limited and there is a more important participation by a number of NGOs and private organizations. This diversity of actors using different approaches has generated disarray in the information system owing to the lack of coherent policies to guide the interaction among actors. This paper uses the case of potato pest control-related information to illustrate changes in local knowledge systems. It differentiates pest control based on indigenous knowledge, chemical control, and integrated pest management (IPM) and explains how changes in the system have influenced the use of these three types of information in AKIS. Currently, the coexistence of different types of potato pest control information promoted and used by diverse and usually unconnected sets of organizations and individuals presents a challenge and requires inter-institutional action guided by clear policies to promote sustainable agriculture.

This commentary argues that theories of cognitive control risk being incomplete unless they incorporate social/emotional factors. Social factors very likely played a critical role in the evolution of human cognitive control abilities, and emotional states are the primary regulatory mechanisms of cognitive control.

The existing numerous adaptive variants of differential evolution have been improved the search ability of classic DE to certain extent. Nevertheless, those variants of DE do not obtain the promising performance in solving black box problems with unknown features, which is mainly because the adaptive rules of those variants are designed according to their designers’ cognition on the problem features. To enhance the optimization ability of DE in optimizing black box problems with unknown features, a differential evolution with (...) autonomous selection of mutation strategies and control parameters is proposed in this paper, inspired by autonomous decision-making mechanism of reinforcement learning. In ASDE, a historical experience archive with population features is utilized to preserve accumulated historical experience of the combination of mutation strategies and control parameters. Furthermore, the accumulated historical experience can be autonomously mapped into rules repository, and the individuals can choose the combination of mutation strategies and control parameters according to those rules. Additionally, an updating and utilization mechanism of the historical experience is designed to assure that the historical experience can be effectively accumulated and utilized efficiently. Compared with some state-of-the-art intelligence algorithms on 15 functions of CEC2015, 28 functions of CEC2017, and parameter extraction problems of the photovoltaic model, ASDE has the advantages of solution accuracy, convergence speed, and robustness in solving black box problems with unknown features.

With an interest in origins, it is proposed that conflict within the group can be taken as a natural focus for exploring the evolutionary development of human moral communities. Morality today involves social control but also the management of conflicts within the group. It is hypothesized that early manifestations of morality involved the identification and collective suppression of behaviours likely to cause such conflict. By triangulation the mutual ancestor of humans and the two Pan species lived in pronounced social dominance (...) hierarchies, and made largely individualized efforts to damp conflict within the group, exhibiting consolation, reconciliation, and active pacifying intervention behaviour. It is particularly the active interventions that can be linked with social control as we know it. It is proposed that when this process became collectivized, and when language permitted the definition and tracking of proscribed behaviour, full-blown morality was on its way. Because early humans lived in egalitarian bands, a likely candidate for the first behaviour to be labelled as morally deviant is not the incest taboo but bullying behaviour, of the type that egalitarian humans today universally proscribe and suppress.

Philosophers, scientists, and other researchers have increasingly characterized humanity as having reached an epistemic and technical stage at which “we can control our own evolution.” Moral–philosophical analysis of this outlook reveals some problems, beginning with the vagueness of “we.” At least four glosses on “we” in the proposition “we, humanity, control our evolution” can be made: “we” is the bundle of all living humans, a leader guiding the combined species, each individual acting severally, or some mixture of these (...) three involving a market interpretation of future evolutionary processes. While all of these glosses have difficulties under philosophical analysis, how we as a species handle our fate via technical developments is all-important. I propose our role herein should be understood as other than controllers of our evolution. (shrink)

Darwinian evolutionary theory has two key terms, variations and biological selection, which finally lead to survival of the fittest variant. With the rise of molecular genetics, variations were explained as results of error replications out of the genetic master templates. For more than half a century, it has been accepted that new genetic information is mostly derived from random error-based events. But the error replication narrative has problems explaining the sudden emergence of new species, new phenotypic traits, and genome innovations (...) as a sudden single event. Meanwhile, it is recognized that errors cannot explain the evolution of genetic information, genetic novelty, and complexity. Now, empirical evidence establishes the crucial role of non-random genetic content editors, such as viruses, diversity generating retroelements, and other RNA networks, to produce new genetic information, complex regulatory control, inheritance vectors, genetic identity, immunity, new sequence space, evolution of complex organisms, and evolutionary transitions.

Official Catholic opposition to contraception has long been portrayed as a stand that is based in antiquated doctrine and “out of touch” with society and its problems. In fact, Catholic arguments often have been less devoted to doctrine and more reflective of concerns for social justice and human rights. This was certainly the case in Latin America, as international birth control programs evolved in the mid to late 20th century. Programs were targeted at developing nations like those in Latin America (...) which were experiencing what was termed a “population explosion.” This article describes how, in this primarily Catholic region, Catholic authorities responded to popula- tion policy, arguing that overpopulation should not be considered the primary cause of economic strife, nor should birth control be promoted as the solution.

Dubreuil (Biol Phil 25:53–73, 2010b , this journal) argues that modern-like cognitive abilities for inhibitory control and goal maintenance most likely evolved in Homo heidelbergensis , much before the evolution of oft-cited modern traits, such as symbolism and art. Dubreuil’s argument proceeds in two steps. First, he identifies two behavioral traits that are supposed to be indicative of the presence of a capacity for inhibition and goal maintenance: cooperative feeding and cooperative breeding. Next, he tries to show that these (...) behavioral traits most likely emerged in Homo heidelbergensis . In this paper, I show that neither of these steps are warranted in light of current scientific evidence, and thus, that the evolutionary background of human executive functions, such as inhibition and goal maintenance, remains obscure. Nonetheless, I suggest that cooperative breeding might mark a crucial step in the evolution of our species: its early emergence in Homo erectus might have favored a social intelligence that was required to get modernity really off the ground in Homo sapiens.

Inferences made from endocasts of fossil skulls cannot provide information on the function of particular neocortical areas or the subcortical pathways to prefrontal cortex that form part of the neural substrate for speech, syntax, and certain aspects of cognition. The neural bases of syntax cannot be disassociated from “communication.” Manual motor control was probably a preadaptive factor in the evolution of humansyntactic ability, but neurophysiological data on living humans show that speech motor control and syntax are more closely linked. (...) The evolution of fully modern speech occurred fairly recently; thoughHomo habilismay have had some degree of speech and syntactic ability, it was not fully modern. Stone tools are uncertain indices of language or cognition. (shrink)

In a social network, a user is greatly influenced by their neighbors’ opinions, and the user’s opinion updating can be regarded as the prisoner’s dilemma game. In view of such considerations, this paper proposes an opinion evolution and control model based on the prisoner’s dilemma game and gives the corresponding opinion evolution and control algorithm. Under different initial positive opinion proportions, different opinion control levels, and the same control threshold value and under different initial positive opinion proportions, different (...) opinion control levels, and different opinion control threshold values in a scale-free network, the experiments illustrate the opinion evolution trends and control strategies according to the measures of changing the opinion control levels and opinion control threshold values for network regulators. The experiments show that the lower the initial positive opinion proportion is and the smaller the control opinion threshold value chosen by the network regulators is, the lower the opinion control level is; the larger the initial positive opinion proportion is and the larger the control opinion threshold value chosen by the network regulators is, the lower the opinion control level is.

This book presents a survey of the molecular basis for the genetic control of living organisms and their evolution. The authors consider four dimensions of control over what shapes life forms: genetic, epigenetic, behavioral, and symbolic/cultural. They pay particular attention to the epigenetic realm, and they defend a view recognizing the genetic incorporation of acquired characteristics – a neo-Lamarckian tack.

The thesis of this paper is that scientific method is to be thought of as a complex many-leveled regulatory hierarchy of principles, interacting with theory also viewed as a complex many-leveled hierarchy. This conception of method is illustrated in particular through one episode in the contemporary development of plasma physics, and related to others. It provides for method-theory interaction and for the development of method itself as science develops.

There is a puzzle in reconciling the widespread presence of puritanical norms condemning harmless pleasures with the theory that morality evolved to reap the benefits of cooperation. Here, we draw on the work of several philosophers to support the argument by Fitouchi et al. that these norms evolved to facilitate and scaffold self-control for the sake of cooperation.

Organisms are self-producing and self-maintaining, or autopoietic systems. Therefore, the course of evolution and adaptation of an organism is strongly determined by its own internal properties, whatever role external selection may play. The internal properties may either act as constraints that preclude certain changes or they open new pathways: the organism canalizes its own evolution. As an example the evolution of feeding mechanisms in salamanders, especially in the lungless salamanders of the family Plethodontidae, is discussed. In this (...) family a large variety of different feeding mechanisms is found. The authors reconstruct this evolutionary process as a series of bifurcation points of either constraints or opportunities forming a sequence of preconditions for the formation of a high-speed projectile tongue characteristic of tropical salamanders. Furthermore, it is shown how parallel evolution of seemingly unrelated domains within an organism such as respiratory physiology, life history biology and pattern of ontogeny has rather direct relevance to the feeding biology, thus demonstrating that organisms always evolve as wholes.

Cancer is most commonly viewed as resulting from somatic mutations enhancing proliferation and invasion. Some hypotheses further propose that these new capacities reveal a breakdown of multicellularity allowing cancer cells to escape proliferation and cooperation control mechanisms that were implemented during evolution of multicellularity. Here we critically review one such hypothesis, named “atavism,” which puts forward the idea that cancer results from the re‐expression of normally repressed genes forming a program, or toolbox, inherited from unicellular or simple multicellular ancestors. (...) This hypothesis places cancer in an interesting evolutionary perspective that has not been widely explored and deserves attention. Thinking about cancer within an evolutionary framework, especially the major transitions to multicellularity, offers particularly promising perspectives. It is therefore of the utmost important to analyze why one approach that tries to achieve this aim, the atavism hypothesis, has not so far emerged as a major theory on cancer. We outline the features of the atavism hypothesis that, would benefit from clarification and, if possible, unification. (shrink)

This paper and its subsequent parts (Part II and Part III) build on an earlier publication (McKenna 1986). They suggest that important clinical data on the relationship between infantile constitutional deficits and microenvironmental factors relevant to SIDS can be acquired by examining the physiological regulatory effects (well documented among nonhuman primates) that parents assert on their infants when they sleep together.I attempt to show why access to parental sensory cues (movement, touch, smell, sound) that induce arousals in infants while they (...) sleep could possibly help one of many different subclasses of infants either to override certain kinds of sleep-induced breathing control errors suspected to be involved in SIDS or to avoid them altogether. I do not suggest that solitary nocturnal sleep “causes” SIDS, that all parents should sleep with their infants, or that traditional SIDS research strategies should be abandoned. However, using evolutionary data, I do suggest that an adaptive fit exists between parent-infant sleep contact and the natural physiological vulnerabilities of the neurologically immature human infant, whose breathing system is more complex than that of other mammals owing to its speech-breathing abilities. This “fit” is best understood, it is argued, in terms of the 4–5 million years of human evolution in which parent-infant contact was almost certainly continuous during at least the first year of an infant’s life. Thus, to dismiss the idea that solitary sleep has no physiological consequences for infants does not accord with scientific facts. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Introduction:Beyond Nature/Culture Dualism: Let's Try Co-Evolution Instead of "Control"Ronnie Hawkins (bio)In the original call for papers for this special issue, nature/culture dualism was characterized as a way of thinking that holds human culture and nonhuman nature to be radically different ontological spheres, hyperseparated and oppositional, or, as Val Plumwood maintains in her essay, an orientation that assumes "separate casts of characters in separate dramas." In the human sphere, (...) individuals are unique and their lives are precious (at least theoretically), with concerns understood "from the inside," in terms of experience, intention and agency. In the sphere of nature, on the other hand, nonhuman beings are seen "from the outside," at best as replaceable members of species or populations needed for ecosystem functioning and, at worst, as unagentive, thinglike objects open for unbridled human exploitation. With our vast information and communication systems now largely in place, however, our human "noösphere" is rapidly enlarging to place us firmly within the biosphere (which, of course, in the imagery of Venn diagrams, must make up the larger circle on the screen), illuminating "both casts in both dramas," or perhaps joining all actors on the stage in a many-act, multidimensional play, the denoument of which, whether or not the extant lifeforms on this [End Page 1] planet will continue to evolve, remains as yet unwritten. The five essays in this collection speak to these points, and together they develop an alternative vision to our present dualistic impasse, seeing multiple natural agencies engaged with humanity in ongoing co-evolution and, as Freya Mathews suggests, raising the hope for a synergistic restructuring of lifeways that may yet save us from anthropogenic catastrophe.In "The Culture of Nature As Seen Through Mississippian Geographies," Jeff Baldwin shows us the broad scope of interacting agents, human and nonhuman, biological and geological, in what he terms "the nature-culture of the Mississippi River," as highlighted by the recent devastation of human habitation along the Gulf Coast of the United States wrought by Hurricanes Katrina and Rita. By enacting a role in which we "believe [our]selves to rule over a mechanistic world," we humans have, over the last century or so, stemmed the natural flooding of the Mississippi, rerouting the sediments that maintained and extended the delta, funneling them into the sea and thereby bringing about the subsidence and erosion of hundreds of square miles of coastal land. Concomitantly, we have let agricultural runoff from the huge Mississippi drainage basin eject excess nutrients into the Gulf of Mexico, stimulating algal blooms and die-offs, depleting the water of oxygen so as to create a hypoxic "dead zone" that is now the size of Massachusetts, and (though Baldwin does not discuss this aspect of the problem) we have released enough petrochemical pollution in the area to have earned the lower reaches of the River the name "Cancer Alley" decades ago. A failure to grasp the import of these large anthropogenic effects is, sadly, evident in calls for rebuilding the New Orleans area according to the same mechanistic model that has already proven so inadequate. Baldwin observes that the earth changes wrought through human cultural innovation often occur so rapidly, or have their negative feedbacks technologically so displaced through time and space, that their eventual impacts on the larger system may initially go unappreciated. His vision of "the culture of nature," however, is ultimately an optimistic one, since his functional understanding of culture is that it ultimately works toward mutualism, promoting increasingly appropriate relationships among all interacting components, and he finds evidence of a growing effort to establish an "intentional co-evolution," a conscious alignment of human projects with the ongoing projects of a living nature that encompasses them. [End Page 2]If Baldwin's essay helps us see our human activities "from the outside"—not just "from within" prevailing human culture, where they seem taken-for-granted necessities given a certain form of social construction, but as they alternatively appear inside biospherical space, often as inappropriate, exploitative interferences and intrusions—Stacey Sowards' essay, "Identification Through Orangutans: Destabilizing the Nature/Culture Dualism," explores the potential for our connecting with nonhuman life "from the inside," relating...

A simple model, illustrating the transition from a population of free swimming, solitary cells to one consisting of small colonies serves as a basis to discuss the evolution of the cooperative group. The transition is the result of a mutation of the dynamics of cell division, delayed cell separation leads to colonies of four cells. With this mutation cooperative features appear, such as synchronised cell divisions within colonies and coordinated flagellar function which enables the colony to swim in definite (...) directions. The selective advantages under given, environmental conditions are defined and the periods necessary for complete allelic replacement in small populations are calculated for asexual and sexual reproduction. The assumption of a steady-state population during allelic substitution is critically considered, particularly under conditions of competition. It is shown that density-dependent population control must operate in the process of selection. Sexual reproduction slows down the rate of selection even though all cells dre haploid. This phenomenon can be explained in general terms of `organizational dominance', where individual units coordinate the function of their neighbours which may be of a different allelotype.Cooperativity is pointed out as an a priori systemic feature which resides in the sub-units of systems, group formation and coordination appears thus as an almost inevitable event. A particular type of system described as ‘closed cycle of positive fitness interaction’ is discussed in more detail. It has the remarkable feature that its members cannot compete with each other; selection takes place between whole cycles .Gonium has a wide spectrum of `somatic plasticity' which enables it to assume various colonial configurations depending on physiological and environmental conditions. This feature can be explained as the result of dynamic flexibilities on the macro-molecular level. The particular relationship between the vast, molecular complexity and the relative simple dynamics of the cell cycle must lead eventually to the genetic fixation of an environmentally induced phenotype.

'Gaining control' tells the story of how human behavioral capacities evolved from those of other animal species. Exploring what is known about the psychological capacities of other groups of animals, the authors reconstruct a fascinating history of our own mental evolution.

Reactions to the target article included requests for extensions and elaborations of the schema we proposed and discussions of apparent shortcomings of our approach. In general, we welcome suggestions for extension of the schema to additional kinds of social behavior and to forms of learning other than Pavlovian conditioning. Many of the requested elaborations of the schema are consistent with our approach, but some may limit its generality. Many of the apparent shortcomings that commentators discussed do not seem problematic. Our (...) schema encourages a broad view of the behavioral consequences of Pavlovian conditioning – including learned modifications of responding to the unconditioned stimulus. Costs and benefits addressed by our schema are the long-range reproductive consequences of learning – not the immediate reinforcing consequences of particular conditioned responses. Our approach allows the evolution of learning to yield maladaptive behavior and can be extended to characterize dynamic social interactions. We clarify that ours is not a homeostatic model involving ideal set points, and we clarify and defend our application of Pavlovian concepts to the analysis of social play. (shrink)

Biological evolution is often viewed narrowly as a change of morphology or allele frequency in a sequence of generations. Here I pursue an alternative informational concept of evolution, as preservation, advance, and emergence of functional information in natural agents. Functional information is a network of signs that are used by agents to preserve and regulate their functions. Functional information is preserved in evolution via complex interplay of copying and construction processes: the digital components are copied, whereas interpreting (...) subagents together with scaffolds, tools, and resources, are constructed. Some of these processes are simple and invariant, whereas others are complex and contextual. Advance of functional information includes improvement and modification of already existing functions. Although the genome information may change passively and randomly, the interpretation is active and guided by the logic of agent behavior and embryonic development. Emergence of new functions is based on the reinterpretation of already existing information, when old tools, resources, and control algorithms are adopted for novel functions. Evolution of functional information progressed from protosemiosis, where signs correspond directly to actions, to eusemiosis, where agents associate signs with objects. Language is the most advanced form of eusemiosis, where the knowledge of objects and models is communicated between agents. (shrink)

Cognitive control is easy to identify in its effects, but difficult to grasp conceptually. This creates somewhat of a puzzle: Is cognitive control a bona fide process or an epiphenomenon that merely exists in the mind of the observer? The topiCS special edition on cognitive control presents a broad set of perspectives on this issue and helps to clarify central conceptual and empirical challenges confronting the field. Our commentary provides a summary of and critical response to each of the papers.

In this article I give a Darwinian account of how sentience, consciousness and language may have evolved. It is argued that sentience and consciousness emerge as brains control purposive actions in new ways.

According to this interpretation, as evolution proceeds, purposive actions play an increasingly important role in the mechanisms of evolution until, with (...) class='Hi'>evolution by cultural means, Darwinian evolution takes on a Lamarckian character. According to this view, as evolution proceeds, the mechanisms of Darwinian evolution themselves evolve. (shrink)

If all origins of life or of any new grade, level, or major transition as such begin with “competitive development”—with juveniles rather than adults, and multiple individuals rather than a single one—then the evolution of progeneration and of replication always requires an explanation. This article proposes that principles of evolutionary ecology such as density-dependence can be used to explain three kinds of developmental repetitions, viz., sequences of inductive and niche-constructing interactions between the ecological environment and population members, which take (...) place in such a way that the sequence is repeated: individual or somatic repetitions, discussed in Section 1, demographic or progenerative repetitions , discussed in Section 2, and replicative repetitions , discussed in Section 3. This results in a statement of the evolutionary process that includes rather than excludes development and ecology, but one which requires some additions to Van Valen’s aphorism that evolution is the control of development by ecology.
