LOS ANGELES TIMES: Can simulating evolution on a computer explain our enormous brains?

Description

Susanne Shultz, who studies evolutionary biology at the University of Manchester took issue not with the methodology, but with the conclusions that were gleaned from the work.

"I have a fairly strong opinions about the utility of trying to divide social and ecological challenges into mutually exclusive categories," she said. "After reading the paper several times, I am still convinced that the model and results are more consistent with a 'socio-ecological' brain. Their argument that they find support for an ecological and not social brain just isn't supported by their results."
