(PHYSorg.com Biology)

In recently published article from Proceedings of the Royal Society B, the relationship between brain size and behavioural ecology was found to be highly sensitive to small data changes, and widely championed hypotheses such as the Social Brain Hypothesis are often predicated on datasets which are not representative. We spoke to lead author, Lauren Powell, from Evolutionary Anthropology Research Group, University of Durham about these findings in her article `Re-evaluating the link between brain size and behavioural ecology in primates.`
