Social 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 ...

15 صفحه اولAllomaternal care, life history and brain size evolution in mammals.
Humans stand out among the apes by having both an extremely large brain and a relatively high reproductive output, which has been proposed to be a consequence of cooperative breeding. Here, we test for general correlates of allomaternal care in a broad sample of 445 mammal species, by examining life history traits, brain size, and different helping behaviors, such as provisioning, carrying, hud...
متن کاملBeyond Feast–Famine: Brain Evolution, Human Life History, and the Metabolic Syndrome
Today, more than 1 billion people are overweight or obese, and the related condition of cardiovascular disease (CVD) accounts for more deaths than any other cause (Mackay et al., 2004). Why this epidemic of metabolic disease has emerged so rapidly in recent history is a classic problem for anthropologists concerned with the role of culture change in disease transition (Ulijaszek and Lofink, 200...
متن کاملNeanderthal brain size at birth provides insights into the evolution of human life history.
From birth to adulthood, the human brain expands by a factor of 3.3, compared with 2.5 in chimpanzees [DeSilva J and Lesnik J (2006) Chimpanzee neonatal brain size: Implications for brain growth in Homo erectus. J Hum Evol 51: 207-212]. How the required extra amount of human brain growth is achieved and what its implications are for human life history and cognitive development are still a matte...
