Natural Selection in the Great Apes
Natural selection is crucial for the adaptation of populations to their environments. Here, we present the first global study of natural selection in the Hominidae (humans and great apes) based on genome-wide information from population samples representing all extant species (including most subspecies). Combining several neutrality tests we create a multi-species map of signatures of natural s...
متن کاملThe last great apes?
F orty years ago, adolescent Figan set off confidently into the woods of Tanzania as though he knew of a food source even richer than the bananas near Jane Goodall's camp. Older and stronger chimpanzees would follow him away. Then he'd lose them and circle back to gorge himself on bananas. One day, a high-ranking male turned up in the meantime and sat eating, in full possession of the site. Whe...
متن کاملImage scoring in great apes.
'Image scoring' occurs when person A monitors the giving behaviour of person B towards person C. We tested for 'image scoring' in chimpanzees, bonobos, gorillas, and orangutans. Subjects passively observed two types of incident: (i) a 'nice' person gave grapes to a human beggar, and (ii) a 'nasty' person refused to give. The subject witnessed both incidents in succession (but was unable to obta...
متن کاملImitation recognition in great apes
testing behaviour in apes as behavioural patterns which were enacted while facing E, if they fell outside of the described repertoire of the species (for example, testing poses; see Figure ), or were combined in non-standard sequences (testing sequences) or uncharacteristically long bouts of repetitions (behaviour repetitions). Out of 46 coded bouts of testing behaviour, four were testing poses...
متن کاملVisual evoked potentials in the great apes.
Visual evoked potentials (VEPs) in response to flash stimuli were recorded from occipital and central-scalp electrodes in the chimpanzee and gorilla. The most notable occipital component of the VEP was a surface-positive wave (P90), the latency of which decreased with development. Central scalp responses, apparent only in older animals, included a characteristic long-latency 'vertex wave' (N125...
