Abstract

Pinson et al . ( 1 ) concluded that the modern human TKTL1 gene is responsible for an increased number of cortical neurons. We show that the “putative Neanderthal variant” of TKTL1 is present in modern human backgrounds. We dispute their argument that this genetic variant is responsible for brain differences in modern humans as opposed to Neanderthals.
