Un error genético cambió la forma en que se desarrollaron nuestras neuronas.
La evolución es un proceso que es fácil apreciar a gran escala, cuando prestamos atención a las distintas especies que han ido apareciendo, transformándose o desapareciendo a lo largo de la historia biológica de nuestro planeta.

Scientists have pinpointed three genes that may have played a pivotal role in an important milestone in human evolution: the striking increase in brain size that facilitated cognitive advances that helped define what it means to be human.

June 2, 2018 CBC Radio Researchers in the U.S. and Europe have identified a unique human gene that seems to be an important factor in our oversized human brains, which are three times the size of our closest relatives, the chimpanzees. The teams found that the gene...

A group of genes that is found only in humans and arose in our ancestors 3–4 million years ago may have driven the evolution of our bigger brains.

Three members of a gene family called NOTCH2NL may have been involved in the evolution of humans’ big cortex.In the last few million years, the brains of humans and human ancestors have quickly evolved to be much bigger and more complex than their primate relatives.

How did humans get so smart? A random reshuffle in our ancestor’s genome more than 3 million years ago let our brains grow three times as large.
