Heterochrony and Cross-Species Intersensory Matching by Infant Vervet Monkeys
BACKGROUND Understanding the evolutionary origins of a phenotype requires understanding the relationship between ontogenetic and phylogenetic processes. Human infants have been shown to undergo a process of perceptual narrowing during their first year of life, whereby their intersensory ability to match the faces and voices of another species declines as they get older. We investigated the evol...
متن کاملThe assessment by vervet monkeys of their own and another species' alarm calls
In Amboseli National Park, Kenya, both superb starlings, Spreo superbus, and vervet monkeys, Cercopithecus aethiops, give acoustically different alarm calls to different classes of predators. The 'raptor alarms' of starlings and vervet monkeys are so called because they are given exclusively to avian species that attack from the air. In contrast, while vervets give 'leopard alarms' to a narrow ...
متن کاملREDIRECTED AGGRESSION AND RECONCILIATION AMONG VERVET MONKEYS, CERCOPITHECUS AETHIOPS by
The data gathered by human observers studying the behavior of nonhuman primates often reveal a social structure of apparently striking complexity. Social groups are composed of a number of different families of different dominance ranks, each of which both competes and cooperates with other families in the group. It is often difficult for the observer to imagine that the monkeys could function ...
متن کاملThe decline of cross-species intersensory perception in human infants.
Between 6 and 10 months of age, infants become better at discriminating among native voices and human faces and worse at discriminating among nonnative voices and other species' faces. We tested whether these unisensory perceptual narrowing effects reflect a general ontogenetic feature of perceptual systems by testing across sensory modalities. We showed pairs of monkey faces producing two diff...
متن کاملSelection of Secondary Growth Areas by Vervet Monkeys ( Cercopithecus aetbiops )
Habitat selection by a group of vervet monkeys (Cercopithecus aethiops) living on the savanna peninsula of St. Kitts was investigated by the intensive sampling of 12 transects. The vervets exhibited nonrandom use of habitats. Examination of 20 ecological variables in each of the habitat types revealed that the vervets preferentially used areas of secondary growth characterized by high density a...
