Big Brains Are All in the Genes

Researchers at the University of Lincoln, UK, have found a clear link between increased brain size and the expansion of gene families related to certain biological functions, furthering the understanding of genetic changes that permitted humans and other mammals to develop such big brains. According to Dr. Humberto Gutierrez, who led the study, “Our results suggest that changes in gene family size may have contributed to the evolution of larger brains in mammals.” Click here to read the full article.
