Two extra copies of the SRGAP2 gene appear to have led to slower human brain development, but denser interconnection between neurons, possibly contributing to our current cognitive abilities. (Total brain interconnectivity correlates moderately well with IQ.)  Makes one wonder about … Continue reading
