Doug, can you explain the above statement further and I hope I have
not taken it too much out of context. Are you saying that Chimp males
have the Y chromosome A haplogroup? If not, has anybody reported on
how close the Chimp Y chromosome haplogroup is to the Haplogroup A in
humans? (Of course, we have the related and unanswerable question, do
all chimp males have the same haplogroup?)
