Homo neanderthalensis

A) Assuming first-order kinetics for the rate of occurrence of random mtDNA SNPs,estimate the number of mtDNA SNPs between toda/s European population Homo sapiens and Neanderthals, Homo neanderthalensis, who split away about 465 kyr ago and are believed to have become extinct. Fig. 10.2...

The main story leads us to two brain centers, both appeared between 500,000 and 200,000 years ago, one known as Homo sapiens neanderthalensis and the other as Homo sapiens sapiens. The brain was large in relation to body size with Neanderthales enjoying an edge of a few cm3 over sapiens. From there on the development of more potent brains was a matter of selection and breeding, the size of brains remained fairly constant once H. sapiens was recognized in its earliest forms. Even today the brain power of individual humans varies by orders of magnitude, but the extremes of humans and apes do not nearly overlap in spite of what we at times contend about each other.
