Biologists Question Animal Brain Size Theory

...s of meat-eating animals -- living and extinct -- shows changes in the size of the animal's brain relative to itself were influenced by more than just sociality within the species. "This is a sophisticated and powerful analysis that integrates fossils with extant species of carnivores," Flynn, dean of th...

The conference highlights man's historical role as prey rather than predator, and human reliance on cooperation, altruism, and sociality for survival and healthy development. The conference will tackle many related questions: How is the negative paradigm of man as predator reflected in ...

...er packs, and driving them into an extinctive vortex. From a conservation standpoint, these results demonstrate how evolutionary strength gained by sociality can be undermined by an Achilles heel that can push species into extinction.

Savanna habitat drives birds, and perhaps others, to cooperative breeding

...tend beyond starlings, Rubenstein said, noting that the first humans also lived in the savannas of East Africa. "We think this relationship between sociality and temporal variability in rainfall and, hence, food availability, might help explain the distribution of cooperative breeding in other groups of bir...

Once the team dated the evolution of the social behaviors to just 20 million to 22 million years ago, they researc...
