Mitochondrial Eve lived after the emergence of Neanderthals, and Y chromosomal Adam lived before Neanderthals. People of European descent are more likely to share genetic material with Neanderthals, but we are not all descendants of Neanderthals. Our main line of descent is from Homo erectus.Of course..... A carrot does not have warm blood or a vision system, so its DNA is not as similar to ours as mammals. But, your DNA, and Neandertal DNA are close to identical.... We are descendants of Neandertals, who are descendants of Adam and Eve.
True. That's where random mutation is needed to add the genetic variation, from which natural selection then prunes according to survival and reproductive success.Natural selection sometimes eliminates...It sometimes leads to extinctions...It always leads to less genetic variation in the gene pool...but it can't create.
