Original sentence: But mitochondrial DNA has only 0.0005% of genome DNA and the mtDNA come from captured bacteria.In 1997, testing performed on mitochondrial DNA extracted from a Neanderthal skeleton showed modern humans and Neanderthals last shared a common ancestor between 500,000 and 800,000 years ago, and furthermore that all modern humans mtDNA, from the Irish to the.Kung people of Africa, are more closely related to each other than to the Neanderthals mtaDNA—further evidence supporting the Out-of-Africa theory
Edited sentence: But ancient lineages, dating to over 1 Mya, in nuclear DNA has been detected (see genetic evidence above).In 1997, testing performed on mitochondrial DNA extracted from a Neanderthal skeleton showed modern humans and Neanderthals last shared a common ancestor between 500,000 and 800,000 years ago, and furthermore that all modern humans, from the ethnic Siberians to the.Kung people of Africa, are more closely related to each other than to the Neanderthals—further evidence supporting the Out-of-Africa theory
