AbstractIn his attempt to find cognitive traits that set humans apart from nonhuman primates with respect to tool use, Vaesen overlooks the primacy of the environment toward the use of which behavior evolves. The occurrence of a particular behavior is a result of how that behavior has evolved in a complex and changing environment selected by a unique population.

AbstractThis article has two goals. The first is to assess, in the face of accruing reports on the ingenuity of great ape tool use, whether and in what sense human tool use still evidences unique, higher cognitive ability. To that effect, I offer a systematic comparison between humans and nonhuman primates with respect to nine cognitive capacities deemed crucial to tool use: enhanced hand-eye coordination, body schema plasticity, causal reasoning, function representation, executive control, social learning, teaching, social intelligence, and language. Since striking differences between humans and great apes stand firm in eight out of nine of these domains, I conclude that human tool use still marks a major cognitive discontinuity between us and our closest relatives. As a second goal of the paper, I address the evolution of human technologies. In particular, I show how the cognitive traits reviewed help to explain why technological accumulation evolved so markedly in humans, and so modestly in apes.

A review of the literature concerning the gross and histologic lesions associated with protozoal and metazoal parasitism in the alimentary tract and pancreas of nonhuman primates is presented. In addition, the natural history, morphology, life cycle, methods for diagnosis, and potential for zoonotic disease are reviewed briefly for each parasite discussed. The parasite species reviewed in detail are those most common or most likely to produce lesions in the alimentary tract and pancreas of the nonhuman primate host. All parasites, both pathogenic and nonpathogenic, in each major group (protozoa: flagellates, sarcodines, sporozoans, neosporans, and ciliates; and metazoa: trematodes, cestodes, nematodes, acanthocephalans, and pentastomids) that have been reported in the nonhuman primate alimentary tract and pancreas are presented in tables.

When asked to describe herself, Koko the nonhuman primate replied in sign-language that she was indeed a ‘fine animal gorilla’. One of several nonhuman primates that have been undergoing language training since the 1970s, Koko’s ability to grasp the fundaments of human expression have caused both fascination and derision in popular and scientific cultures. Yet visions of the language-using ape have not been simply a phenomenon of the twentieth and twenty-first centuries. Early natural history and Enlightenment philosophy make curious reference to the possibility of communicating apes. So similar to the human and yet existing in the terrain of animality, it was believed by some that the ape held a latent capacity for perfectibility — for emerging out of the mute world of the animal into the terrain of the human. An historically liminal entity, the great ape has been cast in both scientific literature and popular culture in various ways as a ‘pre-human’, a species that may be capable of becoming, through a training in the civilized manners and language of the world, fully human. In this sense, striking similarities can be found between the representation of nonhuman primates in contemporary ape language projects and historical discourses linking human childhood with a state of animality.
