The complexity of the brain stems from its connectivity. This is evidenced by the disproportionate increase in the volume of white substance throughout primate evolution even though the “grey matter” is the one that takes the fame; that is, there are more and more “wires” connecting the different cortical regions over long distances according to […]

What differentiates us from our closest relatives and how are these differences caused? Scientists are trying to answer this question by comparing the genomic information of us and our closest relatives. Yet, we are far from having a genomic explanation that justifies the observed phenotypic differences. Human Accelerated Regions (HARs) However, some findings bring us […]
