Grasping primate origins.
The evolutionary history that led to Eocene-and-later primates of modern aspect (Euprimates) has been uncertain. We describe a skeleton of Paleocene plesiadapiform Carpolestes simpsoni that includes most of the skull and many postcranial bones. Phylogenetic analyses indicate that Carpolestidae are closely related to Euprimates. C. simpsoni had long fingers and an opposable hallux with a nail. I...
متن کاملRethinking the Origins of Agriculture Human Behavioral Ecology, Phenotypic (Developmental) Plasticity, and Agricultural Origins
The fields of human behavioral ecology (HBE) and evolutionary developmental biology (evo-devo) both stand to make significant contributions to our understanding of agricultural origins. These two approaches share a concern with phenotypic plasticity and its evolutionary significance. HBE considers the adaptive plasticity of the human phenotype in response to resource distribution in time and sp...
متن کاملOrigins and Impacts of Primate Segmental Duplications
Duplicated sequences are substrates for the emergence of new genes and are an important source of genetic instability associated with rare and common disease. Analyses of primate genomes have shown an increase in the proportion of interspersed segmental duplications within the genomes of humans and great apes. This is in contrast to other mammalian genomes that appear to have their recently dup...
متن کاملEcology and evolution of primate colour vision.
More than one hundred years ago, Grant Allen suggested that colour vision in primates, birds and insects evolved as an adaptation for foraging on colourful advertisements of plants--fruits and flowers. Recent studies have shown that well developed colour vision appeared long before fruits and flowers evolved. Thus, colour vision is generally beneficial for many animals, not only for those eatin...
متن کاملPrimate polemic: commentary on Smith, Couchman, and Beran (2014).
Smith, Couchman, and Beran (2014, pp. 115-131) take issue with recent attempts to account for so-called metacognitive behavior in nonhuman animals in terms of simple processes of associative reinforcement learning. Their arguments rely on appeals to unconvincing and equivocal empirical evidence, and a misrepresentation of the nature of associative learning. Although the existing data do not rul...
