The evolution of the social brain: anthropoid primates contrast with other vertebrates.
The social brain hypothesis argues that large brains have arisen over evolutionary time as a response to the social and ecological conflicts inherent in group living. We test predictions arising from the hypothesis using comparative data from birds and four mammalian orders (Carnivora, Artiodactyla, Chiroptera and Primates) and show that, across all non-primate taxa, relative brain size is prin...
متن کاملSocial life, evolution of intelligence, behaviour and human brain size
Social life is one of the most critical factors of the evolution of the behavior of non-human primates and humans. Several factors, such as an increase in brain size, adaptive modules, and grooming, are related to the complexities of social groups. Although some scientists have mentioned foraging as a rival hypothesis for the evolution of behavior, in this research, we tried to investigate the ...
متن کاملCorrelated evolution of brain regions involved in producing and processing facial expressions in anthropoid primates.
Anthropoid primates are distinguished from other mammals by having relatively large primary visual cortices (V1) and complex facial expressions. We present a comparative test of the hypothesis that facial expression processing coevolved with the expansion of V1 in anthropoids. Previously published data were analysed using phylogenetic comparative methods. The results of our study suggest a patt...
متن کاملRelative volume of the cerebellum in dolphins and comparison with anthropoid primates.
According to the 'developmental constraint hypothesis' of comparative mammalian neuroanatomy, brain growth follows predictable allometric trends. Therefore, brain structures should scale to the entire brain in the same way across mammals. Evidence for a departure from this pattern for cerebellum volume has recently been reported among the anthropoid primates. One of the mammalian groups that ha...
متن کاملAdaptive Evolution of Four Microcephaly Genes and the Evolution of Brain Size in Anthropoid Primates Authors:
The anatomical basis and adaptive function of the expansion in primate brain size have long been studied; however we are only beginning to understand the genetic basis of these evolutionary changes. Genes linked to human primary microcephaly have received much attention as they have accelerated evolutionary rates along lineages leading to humans. However these studies focus narrowly on apes and...
