Evolution Quote by D.F. Swaab
““of now, the main difference has been found in the HAR1 (human accelerated region 1), a segment of a recently discovered RNA gene. The RNA that is expressed in early development (HAR1F) is specific to the reelin-producing Cajal-Retzius cells in the brain. HAR1F comes to expression together with reelin in the seventeenth to nineteenth weeks of fetal development, a crucial stage in the formation of the six-layered cerebral cortex. The mutations in this human gene are probably over a million years old and could have played a crucial role in the emergence of modern humankind. Throughout our evolution, an enormous””

The HAR1F gene, active during early brain development, may have been pivotal in the evolution of modern humans, influencing cortical formation.
In simple terms: HAR1F gene helped shape modern human brains.
