Neuroscience has made astounding progress in the understanding of the brain. What should we make of its claims to go beyond the brain and explain consciousness, behaviour and culture? Where should we draw the line? In this brilliant critique Raymond Tallis dismantles "Neuromania", arising out of the idea that we are reducible to our brains and "Darwinitis" according to which, since the brain is an evolved organ, we are entirely explicable within an evolutionary framework. With precision and acuity he argues (...) that the belief that human beings can be understood in biological terms is a serious obstacle to clear thinking about what we are and what we might become. Neuromania and Darwinitis deny human uniqueness, minimise the differences between us and our nearest animal kin and offer a grotesquely simplified account of humanity. We are, argues Tallis, infinitely more interesting and complex than we appear in the mirror of biology. Combative, fearless and thought-provoking, _Aping Mankind_ is an important book and one that scientists, cultural commentators and policy-makers cannot ignore. This Routledge Classics edition includes a new preface by the Author. (shrink)

Apes imitate the effects of others' actions, but the evidence for program-level imitation seems contradictory and the evidence against bodily imitation and trial and error in learning the organization of complex activities seems ambiguous. Action-level imitations are more flexible than described and may derive from imitation of the effects of others' actions on objects.

I defend a Mengzian version of the Social Intelligence Hypothesis, according to which humans think about one another’s beliefs and desires—and reasons for action—in order to solve our social living problems through cooperation, rather than through competition and deception, as the more familiar Machiavellian version has it. Given this framework, and a corresponding view about the function of belief attribution, I argue that while apes need not attribute propositional attitudes to pass the “false belief task,” we should not conclude (...) that apes may be behaviorists. Rather, the Mengzian Social Intelligence Hypothesis perspective offers another interpretation of ape behavior, intermediate between behaviorist and propositional attitude schemas. I argue that the false belief task can be solved by individuals who have an agency schema which takes others to be minded beings who have goals, emotions, and perceptions, but who fail to consider propositional attitudes or reasons for behavior. I then argue that a true test of belief attribution in great apes would be one that shows they seek explanations in terms of reasons for behavior. However, no such test yet exists. (shrink)

Recent advances in evolutionary biology and ethology suggest that humans are not the only species capable of empathy and possibly morality. These findings are of no little consequence for theology, given that a nonhuman animal as a free moral agent would beg the question if human beings are indeed uniquely created in God's image. I argue that apes and some other mammals have moral agency and that a traditional interpretation of the imago Dei is incorrectly equating specialness with exclusivity. (...) By framing the problem in terms of metaphor, following the work of Paul Ricoeur and Sallie McFague, I propose that the concept of the imago Dei could be extended to accommodate moral species other than our own.

In a devastating critique Raymond Tallis exposes the exaggerated claims made for the ability of neuroscience and evolutionary theory to explain human consciousness, behaviour, culture and society. While readily acknowledging the astounding progress neuroscience has made in helping us understand how the brain works, Tallis directs his guns at neuroscience’s dark companion – "Neuromania" as he describes it – the belief that brain activity is not merely a necessary but a sufficient condition for human consciousness and that consequently our everyday (...) behaviour can be entirely understood in neural terms. With the formidable acuity and precision of both clinician and philosopher, Tallis dismantles the idea that "we are our brains", which has given rise to a plethora of neuro-prefixed pseudo-disciplines laying claim to explain everything from art and literature to criminality and religious belief, and shows it to be confused and fallacious, and an abuse of the prestige of science, one that sidesteps a whole range of mind–body problems. The belief that human beings can be understood essentially in biological terms is a serious obstacle, argues Tallis, to clear thinking about what human beings are and what they might become. To explain everyday behaviour in Darwinian terms and to identify human consciousness with the activity of the evolved brain denies human uniqueness, and by minimising the differences between us and our nearest animal kin, misrepresents what we are, offering a grotesquely simplified and degrading account of humanity. We are, shows Tallis, infinitely more interesting and complex than we appear in the mirror of biologism. Combative, fearless and always thought-provoking, _Aping Mankind _is an important book, one that scientists, cultural commentators and policy-makers cannot ignore. (shrink)

Ape to Apollo is the first book to follow the development in the eighteenth century of the idea of race as it shaped and was shaped by the idea of aesthetics.

An Ape Ethic and the Question of Personhood proposes that differences between humans and apes provide the foundation for the call to recognize forest personhood in the great apes. While all ape species are alike in terms of cognition, intelligence, and social behaviors, great apes, not humans, are efficient ecosystem engineers.

Compared to other animals, humans appear to have a special motivation to share experiences and mental states with others (Clark, 2006;Grice, 1975), which enables them to enter a condition of ‘we’ or shared intentionality (Tomasello & Carpenter, 2005). Shared intentionality has been suggested to be an evolutionary response to unique problems faced in complex joint action coordination (Levinson, 2006;Tomasello, Carpenter, Call, Behne, & Moll, 2005) and to be unique to humans (Tomasello, 2014). The theoretical and empirical bases for this claim, (...) however, present several issues and inconsistencies. Here, we suggest that shared intentionality can be approached as an interactional achievement, and that by studying how our closest relatives, the great apes, coordinate joint action with conspecifics, we might demonstrate some correlate abilities of shared intentionality, such as the appreciation of joint commitment. We provide seven examples from bonobo joint activities to illustrate our framework. (shrink)

Ontogeny, specifically the role of language in the human family now and in prehistory, is central to Locke & Bogin's (L&B's) thesis in a compelling way. The unique life-history stages of childhood and adolescence, however, must be interpreted not only against an exceptionally “high quality” human infancy but also in light of the evolution of co-constructed, emotionally based communication in ape, hominid, and human infancy.

In contrast to apes’ seemingly sophisticated skill at producing pointing gestures referentially, the comprehension of other individual’s pointing gestures as a source of indexical information seems to be less pronounced.One reason for apes’ difficulty at comprehending pointing gestures might be that in former studies they were mainly confronted with human declarative pointing gestures, whereas apes have largely been shown to point imperatively and towards humans. In the present study bonobos, chimpanzees and orangutans were confronted with a conspecific’s (...) imperative pointing gesture in a competitive context, therefore mirroring former studies that have investigated apes’ skills at producing these gestures.However, apes in the present study did not use their conspecific’s pointing gestures. Apes have been shown to use indexical information when provided noncommunicatively and to interpret other individuals’ actions in terms of motives. Thus, it is discussed whether apes treat a pointing gesture as intentional act of indexical reference. (shrink)

The Ape that Understood the Universe is the story of the strangest animal in the world: the human animal. It opens with a question: How would an alien scientist view our species? What would it make of our sex differences, our sexual behavior, our child-rearing patterns, our moral codes, our religions, our languages, and science? The book tackles these issues by drawing on ideas from two major schools of thought: evolutionary psychology and cultural evolutionary theory. The guiding assumption is that (...) humans are animals, and that like all animals, we evolved to pass on our genes. At some point, however, we also evolved the capacity for culture - and from that moment, culture began evolving in its own right. This transformed us from a mere ape into an ape capable of reshaping the planet, travelling to other worlds, and understanding the vast universe of which we're but a tiny, fleeting fragment.

In Becoming Human (2021), evolutionary psychologist Michael Tomasello provides a comprehensive account of the social intentionality which makes us human. One of the many themes discussed is the intentionality required for switching between perspectives. A number of interesting claims are made in these parts, including that great apes (and young infants) have no sense of perspective, no understanding of false beliefs, and do not know they could be wrong about how they experience things. While I am sympathetic to the (...) general purport of Tomasello’s theory of switching perspectives, I believe his theory mispresents the intentional skills that are involved in various pre-conceptual forms of switching perspectives, to the extent that it is worth a brief commentary. I first outline Tomasello’s theory of perspectivalness, and subsequently develop an alternative, based on the phenomenological distinction between operative and thematic intentionality. (shrink)

This paper examines the meaningfulness of pointing in great apes. We appeal to Hannah Ginsborg’s conception of primitive normativity, which provides an adequate criterion for establishing whether a response is meaningful, and we attempt to make room for a conception according to which there is no fundamental difference between the responses of human infants and those of other great apes to pointing gestures. This conception is an alternative to Tomasello’s view that pointing gestures and reactions to them reveal (...) a fundamental difference between humans and other apes. (shrink)

Das Great Ape Project ist eine tierschutzpolitische Bewegung, die auf die Veröffentlichung des Sammelbands TheGreatApeProject:EqualityBeyondHumanity durch die Ethikerin Paola Cavalieri und den Ethiker Peter Singer im Jahr 1993 zurückgeht. Der Band erschien 1994 in deutscher Übersetzung unter dem Titel MenschenrechtefürdieGroßenMenschenaffen.DasGreatApeProject. Die rund 40 internationalen Autorinnen und Autoren verbindet das Bestreben, den Großen Menschenaffen, d. h. Schimpansen, Orang-Utans und Gorillas drei Rechte zuzusprechen und diese in der Praxis durchzusetzen, die menschlichen Grundrechten entsprechen: Das Recht auf Leben, das Recht auf individuelle Freiheit, (...) das Verbot der Folter. Entsprechend diesen Postulaten richtet sich das Great Ape Project hauptsächlich gegen die Verdrängung der Großen Menschenaffen in ihren Ursprungsgebieten, insbesondere durch Jagd und Wilderei, aber auch durch die Zerstörung ihrer Lebensgrundlagen, gegen die Haltung von Großen Menschenaffen in Zoologischen Gärten oder zu Vergnügungszwecken und gegen belastende Tierversuche mit Menschenaffen zu medizinischen oder anderen Zwecken. In Deutschland arbeitet das Great Ape Project eng mit der Giordano-Bruno-Stiftung zusammen, insbesondere nachdem die Stiftung 2011 ihren Ethik-Preis an Paola Cavalieri und Peter Singer vergeben hat. Sprecher des Projekts in Deutschland ist der Psychologe Colin Goldner, Autor des Reports über die Haltung von Menschenaffen in deutschen Zoologischen Gärten. Unterstützt wird die Bewegung u. a. von dem in London lehrenden Zoologen und Affenforscher Volker Sommer. (shrink)

The debate over ape personhood is of great social and moral importance. For more than twenty-five years, attorney Steven Wise has been arguing that animals who have cognitive complexities similar to humans should be legally granted basic rights of au- tonomy. In my view, granting personhood status and other rights to great apes are at- tainable goals. But how should we go about it?

Once upon a time, not too long ago, the question about apes and ethics had to do with moral standing—do apes have interests or rights that humans ought to respect? Given the fifty years of research on great ape cognition, life history, social organization, and behavior, the answer to that question seems obvious. Apes have emotions and projects, they can be harmed, and they have important social relationships.

Shanker & King (S&K) rightly stress that recent ape language research has important implications for language development and origins. But the evidence does not warrant their conclusion that we can dispense with representations. Indeed, their own discussion of the nature of communication highlights the central role that representations must play in our models of communicative competence, in and out of language.

In The Ciceronian, Erasmus ridiculed as "apes" humanists who imitated Cicero superficially. Methods developed in cognitive literary theory provide a framework for understanding that these simian metaphors are not just ornamental: they are integral to the dialogue's meaning, helping to configure the connections that it draws between literary style and paganism. Metaphorical blending in the Ciceronianus takes on added significance when read alongside the Adages, in which Erasmus glossed classical sayings about monkeys to comment on simian and human nature. (...) The blending of conceptual metaphors both within and between these texts is itself the process by which new meanings emerge. (shrink)

There are good arguments for examining great ape communicative achievements for what they contribute to our understanding of great ape cognition and its evolution (Russon & Begun, in press a). Our concern is whether Shanker & King's (S&K's) thesis advances communication studies from a broader cognitive and evolutionary perspective.

In Tague's book, An Ape Ethic and the Question of Personhood, he presents his call for what he refers to as “Ape Forest Sovereignty” in three parts. In the first part of the book, he explores “The Case for an Ape Ethic.” Here he lays the groundwork for his call for Ape Forest Sovereignty, arguing that apes are ethical players in both their ecosystems and within their society's social structures. He explores this argument through the lens of “personhood,” a (...) concept that he recognizes as having multiple facets: legal, ethical, and metaphysical. He is clear that, in his exploration of the concept of personhood, “An Ape Ethic is not a legal argument but, nonetheless, a call for recognition of great apes as persons of tropical forests” (p. 4). This point is where I find the book somewhat lacking in ways that I will explore later in this review.Tague goes on in Part 2, which deals with cognition and environmental adaptation, and Part 3, which deals with the complex social interactions in ape societies, to build a convincing and extremely well-referenced argument, leaving the reader in little doubt as to his call that, if humans can be considered “persons,” there is very good reason to also consider apes as “persons,” too. These parts of the book will be useful for those interested in ape cognition and social structure as they bring together both historical and current work on this issue from a truly global perspective. It is perhaps the most current and comprehensive analysis of these points in print today and will serve students and those with an interest in those subjects extremely well.In addition to possessing the relevant cognitive and social attributes that would see them considered “persons,” Tague further argues that great apes—and he makes particular mention of orangutans throughout the book—operate in such a way that is intrinsically morally good in their interactions with their environment. Indeed, the existence of great apes in forest environments, says Tague, actively benefits those environments, particularly in their role as important seed dispersers. Tague argues that this establishes great apes as “moral eco-engineers” who, in stark contrast to the damaging capitalist social and political structures maintained by humans that have had such devastating impact on global forest environments, actively benefit their environment.Drawing together the various threads of his analysis, Tague argues that apes should be considered “forest persons” and be granted sovereignty over their forest land.Frustratingly, having laid an intricate groundwork as the basis of his call for ape personhood that, he says, is the rationale for the call for ape land sovereignty, Tague devotes very little of the book to his radical and compelling call. I had hoped that the final chapter of the book would explore exactly what ape sovereignty might look like in practice. The book left me with more questions than answers in this regard, and I would have liked Tague to explore the practical potential of his call in his concluding chapter.An exploration of the practical outcomes would be complex and could not help but become not just ethical, but also political and legal in nature. Land sovereignty cannot just be considered through an ethical lens, but must be addressed though the political and legal constructs upon which the principle of land sovereignty is based. For example, I would have liked to have seen Tague's work explore the following questions: How would nation states within whose jurisdiction these forests are located cede sovereignty to apes and how might it be maintained or managed?How would humans living or working in these forests, particularly those with long-standing ancestral land rights over the same land in question, interact with apes within these spaces?How would other nonhuman species who also share the environment engage and exist within these spaces? Would or could there be any feasible ceding of land sovereignty to nonhuman species when the principle of land sovereignty is based on human-made political and legal principles and, indeed, while indigenous human populations continue to struggle for their sovereignty to be recognized and respected?I was also left wondering how Tague's call might apply to captive apes. The theory espoused in the book relies heavily on land sovereignty being granted to apes on the basis of them being “moral eco-engineers” of their forest homes. I would be interested to understand where this might leave apes born or maintained in captivity who cannot, and will not, ever form part of free-living societies in those forest environments. If ape personhood and, by extension, the right to land sovereignty, is contingent on those apes playing a positive conservation role in their natural environment, one can perhaps conclude that captive apes are excluded from personhood recognition due to their inability to play this role. I would be interested to understand where Tague positions captive apes within his theory.Important work has been done in this academic area, most notably by Donaldson and Kymlicka (2013) in their book Zoopolis and, specifically, in the chapter “Wild Animal Sovereignty.” Tague does reference this work in parts of his text and it may be that An Ape Ethic and Zoopolis could be read together, with the arguments of one informing, and providing context, to the other. That said, I would have been interested to understand Tague's specific view on the practical implementation of his call for ape land sovereignty, perhaps in a volume of work to accompany the text currently under consideration.Tague's book presents an urgent and compelling argument that, under human management, forest habitats are under immediate threat of irreparable harm. His call to cede land to nonhuman “forest persons” who will better care for and maintain this land—which is vital for the health and welfare of all living beings on Earth—is a radical and important one. I hope Tague continues to develop and expand on this work in the near future to explore the way in which his call might be realized in practice. (shrink)

Pointing by apes is near-ubiquitous in captivity, yet rare in their natural habitats. This has implications for understanding both the ontogeny and heritability of pointing, conceived as a behavioral phenotype. The data suggest that the cognitive capacity for manual deixis was possessed by the last common ancestor of humans and the great apes. In this review, nonverbal reference is distinguished from symbolic reference. An operational definition of intentional communication is delineated, citing published or forthcoming examples for each of (...) the defining criteria from studies of manual gestures in apes. Claims that chimpanzees do not point amongst themselves or do not gesture declaratively are refuted with published examples. Links between pointing and cognitive milestones in other domains relating means to ends are discussed. Finally, an evolutionary scenario of pointing as an adaptation to changes in hominid development is briefly sketched. (shrink)

It is sometimes argued that while human gestures are produced ostensively and intentionally, great ape gestures are produced only intentionally. If true, this would make the psychological mechanisms underlying the different species’ communication fundamentally different, and ascriptions of meaning to chimpanzee gestures would be inappropriate. While the existence of different underlying mechanisms cannot be ruled out, in fact claims about difference are driven less by empirical data than by contested assumptions about the nature of ostensive communication. On some accounts, there (...) are no reasons to doubt that great ape gestural communication is ostensive. If these accounts are correct, attributions of meaning to chimpanzee gestures would be justified. (shrink)

The proposal to add the behavioral momentum metaphor to Skinnerian psychology and the use of other borrowed physical explanatory concepts such as velocity and inertial mass has only superficial value. The basic problem is that, in contrast to Newtonian physics, the “laws” do not apply to a significant proportion of the phenomena to be explained, and these evidential discrepancies are ignored, rather than being used to modify the scientific explanations and improve technological applications that are based on those explanations.

The literature of bioethics suffers from two serious problems. (1) Most authors are unable to take seriously both the rights of the great apes and of severely disabled human infants. Rationalism—moral status rests on rational capacities—wrongly assigns a higher moral status to the great apes than to all severely disabled human infants with less rational capacities than the great apes. Anthropocentrism—moral status depends on membership in the human species—falsely grants all humans a higher moral status than the (...) great apes. Animalism—moral status is dependent on the ability to suffer—mistakenly equates the moral status of humans and most animals. (2) The concept person is widely used for justificatory purposes, but it seems that it cannot play such a role. It seems that it is either redundant or unable to play any justificatory role. I argue that we can solve the second problem by understanding person as a thick evaluative concept. This then enables us to justify assigning a higher moral status to the great apes than to simple animals: the great apes are persons. To solve the first problem, I argue that certain severely disabled infants have a higher moral status than the great apes because they are dependent upon human relationships for their well-being. Only very limited abilities are required for such relationships, and the question who is capable of them must be based on thick evaluative concepts. Thus, it turns out that to make progress in bioethics we must assign thick evaluative concepts a central role. (shrink)

This essay draws on Adam Smith’s moral sentimentalism to critique primatologist Frans de Waal’s gradualist theory of human morality. De Waal has spent his career arguing for continuity between primate behavior and human morality, proposing that empathy is a primary moral building block evident in primate behavior. Smith’s moral sentimentalism—with its emphasis on the role of sympathy in moral virtue—provides the philosophical framework for de Waal’s understanding of morality. Smith’s notion of sympathy and the imagination involved in sympathy is qualitatively (...) different from animal sympathy. I argue that Smithian sympathy includes the ability to represent propositional attitudes and take into account multiple perspectives which are then synthesized into a singular impartial perspective. Furthermore, Smithian moral judgment requires the capacity for emotion regulation and moral self-cultivation, or the ability to shape and control one’s reactive attitudes. Taken together, these capacities far outstrip the capacities of animals, disrupting de Waal’s gradualism. (shrink)

In this paper I focus on the figure of the ape in Nietzsche's texts, and how it fits into his putative naturalism. I examine the lowly status and ignoble qualities that he associates with this animal and argue that they betray a residual anthropocentricism profoundly at odds with Nietzsche's dehumanized conception of nature. Accordingly, I suggest a reading of Nietzsche's ape remarks that brings them more into accord with his non-teleological and non-hierarchical conception of species. Ultimately, I argue that a (...) robust, thorough going Nietzschean naturalism would require the affirmation of the ape, including everything it comes to represent for Nietzsche. (shrink)

The “fearful ape hypothesis” is interesting but is currently underspecified. We need more research on whether it is specific to fear, specific to humans (or even cooperative breeders in general), what is included in “fear,” and whether these patterns would indeed evolve despite arms races to extract help from audiences. Specifying these will result in a more testable hypothesis.

This edited volume of essays provides an interdisciplinary philosophical analysis of the Planet of the Apes franchise, addressing themes of intelligence, language, time travel, research ethics, and the evolving status of CGI characters. Through a range of essays, the volume examines how the apes’ society mirrors human civilization, challenging assumptions about intelligence, moral worth, and speciesism. Key themes include language as a criterion for intelligence, the ethics of experimentation, and the treatment of sentient beings.

In the fearful ape hypothesis, Grossmann argues that heightened fearfulness increases human-unique cooperation. We suggest that this conclusion, however, may be premature. In particular, we question Grossmann's singling out of fear as the affective trait that enhances cooperative care. Additionally, we problematize the extent to which heightened fearfulness in humans, and its association with human-unique cooperation, are supported empirically.

In Of Apes and Ancestors, Ian Hesketh attempts to de-mythologize the famous Oxford debate between Samuel Wilberforce, the bishop of Oxford, and Charles Darwin’s friends, Thomas Huxley and Joseph Hooker. Hooker and Huxley clashed publicly with Wilberforce at a meeting of the British Association for the Advancement of Science (BAAS) in June of 1860. At issue was the scientific content and general implication of Darwin’s Origin of Species. Hesketh argues that this event is best understood as a minor episode (...) in a complex web of personal and professional rivalries between two generations of naturalists. He further argues that Huxley aggressively reinterpreted the actual events of the debate for years afterwards, turning them into a “Galileo moment” for the nineteenth century, a moment in which science bravely stood up to religious authority and refused to back down. While his treatment of the debate and its context is well supported, the connection Hesketh draws between Huxley’s narrative and modern historiography is somewhat tenuous. (shrink)

From an early age, humans know a surprising amount about basic physical principles, such as gravity, force, mass, and shape. We can see this in the way that young children play, and manipulate objects around them. The same behaviour has long been observed in primates - chimpanzees have been shown to possess a remarkable ability to make and use simple tools. But what does this tell us about their inner mental state - do they therefore share the same understanding to (...) that of a young child? Do they understand the simple, underlying physical principles involved? Though some people would say that they do, this book reports groundbreaking research that questions whether this really is the case. -/- Folk Physics for Apes challenges the assumptions so often made about apes. It offers us a rare glimpse into the workings of another mind, examining how apes perceive and understand the physical world - an understanding that appears to be both similar to, and yet profoundly different from our own. The book will have broad appeal to evolutionary psychologists, developmental psychologists, and those interested in the sub-disciplines of cognitive science (philosophy, anthropology). The book additionally offers for developmental psychologists some valuable new non-verbal techniques for assessing causal understanding in young children. (shrink)

Humans are moral creatures. Among all life on Earth, we alone experience rich moral emotions, follow complex rules governing how we treat one another, and engage in moral dialogue. But how did human morality evolve? And can humans become morally evolved? -/- In A Better Ape, Victor Kumar and Richmond Campbell draw on the latest research in the biological and social sciences to explain the key role that morality has played in human evolution. They explore the moral traits that humans (...) share with chimpanzees; how a more complex moral mind enabled Homo sapiens to arise and out-compete other human species; and the place of morality alongside historic revolutions in technology and social organization. Throughout the book, Kumar and Campbell argue that morality co-evolved with intelligence and complex sociality. Morality prevents societal collapse and enables complex knowledge. -/- After unearthing the ancient origins of human morality, Kumar and Campbell use evolutionary theory to deliver profound insights about how to advance moral progress and resist moral regress, such as reducing animal suffering on industrial farms; capitalizing on the recent revolution in gay rights to foster a nascent revolution in transgender rights; opposing intersectional inequality that impacts women and people of color in lower socioeconomic classes; and addressing major problems of global inequality, especially impending crises of injustice caused by anthropogenic climate change. Understanding how we evolved--and how we continue to evolve--can help us become a better ape. (shrink)

Disagreement remains about whether particular human socio-cognitive traits arose primarily as a result of biological adaptations, or because of changing cultural practices. Heyes argues that uniquely human traits, including imitation and theory of mind, are the product of cultural learning. In contrast, Tomasello argues that they are, in key respects, part of a suite of adaptations for ‘shared intentionality’. We consider how such disagreements might be resolved. We show that the kinds of consideration often used to adjudicate questions about trait (...) origins are insufficient to settle origin questions. Furthermore, humankind’s immersion in culture undermines the prospect that cross-cultural and developmental studies could resolve origin questions. Nonetheless we argue that, when cautiously interpreted, currently neglected studies of enculturated great apes (i.e. apes raised in human environments) can shed new light on trait origins, and inform mechanistic accounts of cognitive development. While acknowledging the shortcomings of enculturation research, we argue that it deserves renewed attention. (shrink)

Attempted answers are given to whether nonhuman great apes also have evolved imitation ; whether humans can transmit imitation as a gadget to apes ; whether human-to-ape transmission can kickstart subsequent and stable ape cultural evolutionary psychology ; and when CEP evolved in our lineage.

The “straw man” prior expectation of the dominant social psychology paradigm is that humans should behave with perfect rationality and high ethical standards. The more modest claim of evolutionary psychologists is that humans have evolved specific adaptations for adaptive problems that were reliably present in the ancestral environment. Outside that restricted range of problems, one should not expect optimal behavior.
