"In human genetics, Haplogroup DE is a human Y-chromosome DNA haplogroup. It is defined by the single nucleotide polymorphism (SNP) mutations, or UEPs, M1(YAP), M145(P205), M203, P144, P153, P165, P167, P183.
Haplogroup DE is often referred to by the most well-known unique event polymorphism (UEP) which defines it, the Y-chromosome Alu Polymorphism (YAP). The YAP mutation was caused when a strand of DNA called Alu, which copies itself, inserted a copy into the Y chromosome. A Y chromosome that has the YAP mutation is called YAP-positive (YAP+), and a Y chromosome that does not have the YAP mutation is labeled YAP-negative (YAP-).
Haplogroup DE is an estimated 65,000 years old" Wikipedia

So hell bent are scientist on proving their initial Out of East Africa theory that despite the absence of this Haplogroup (DE) in the Asian sub-continent, they continue to barrel away at it, when Massey's explanation for the Maori presence in South Asia serves as the perfect explanation for the presence of DE in Nigeria, and D in both Japan and the Andaman Islands. If Haplogroup E is found in the Gabon region of Cameroon among the Baka, and according to all historical sources the Baka are representative of the first humans, and the forest has been their primeval home, why do we need to look to East Africa for their genetic origins?

"Some have hypothesized that Haplogroups C and D were brought together to East Asia by a single population that became the first successful modern human colonizers of that region, but at present the distributions of Haplogroups C and D are different, with various subtypes of Haplogroup C being found at high frequency among the Australian aborigines, Polynesians, Vietnamese, Kazakhs, Mongolians, Manchurians, Koreans, and indigenous inhabitants of the Russian Far East and at moderate frequencies elsewhere throughout Asia and Oceania, including India and Southeast Asia, whereas Haplogroup D is found at high frequencies only among the Tibetans, Japanese peoples, and Andaman Islanders, and has been found neither in India nor among the aboriginal inhabitants of the Americas or Oceania."

Why isn't this a perfect example of evolution at work? Doesn't this suggest what scientists have been postulating for decades; that those who remain isolated on Oceanic islands keep their original DNA and exhibit less diversity than those who migrate onto large land masses and are subjected to environmental changes? Though in this case it is more likely that the DE or D/E carriers encountered a previously established and physically stronger hominid and hybridization occured, for how does one explain the proximity of origin.
