Genetic study of Neanderthal DNA reveals early split between humans and Neanderthals
...umans did not occur," Rubin said, "analysis of the nuclear
DNA from the Neanderthal suggests the low likelihood of it having occurred at any appreciable level." According to the authors, "If Neanderthal admixture did indeed occur, then [it would] manifest in our data as an abundance of low-frequency derived...

Neanderthal genome sequencing yields surprising results and opens a new door to future studies
...though mtDNA tends to remain preserved longer than nuclear
DNA, it provides limited biological information. The vast majority of the genome is comprised of nuclear

genes may evolve more slowly or more rapidly with population drift. Surprisingly, the researchers found that although the lemurs appeared to be different species because they were visually distinct, they did not differ genetically. According to the...
