We have more Neanderthal ancestry than we thought

“In 2017 we found a second complete Neanderthal genome, revealing that some of human “parent’s” genes were Neanderthal all along. Ultimately, this wound up showing that non-African Neanderthal ancestry was ~20% higher than we thought. …

Researchers have been underestimating the amount of Neanderthal DNA in non-African populations. New work helps fix this problem, confirming we have ~20% more Neanderthal DNA than expected… small amount overall (<5%).”

Now this from, Jan. 29,

Neanderthal Genes Influenced Modern Human Brain Development

“The strongest evidence they [Max Plank Inst.] found for effects on gene activity were in the basal ganglia and cerebellum, which receive direct input from the motor cortex and regulate movement.”

This is a critical region of the brain, responsible for cognitive functions.

“The basal ganglia are associated with a variety of functions, includingcontrol of voluntary motor movements, procedural learning, habit learning, eye movements, cognition, and emotion.”  — Google definitions

Whites are the only modern human sub-species with exclusively Neanderthal DNA.  Asians have admixture with Denisovan and Homo erectus.  Africans have zero Neanderthal or Denisovan.
