Ken / List

If I understand things - the researchers are saying:

1. The Homo sapiens and Neanderthal lines separated some 500,000 years ago.

2. Time passed - possibly 200,000 years - and genes in each group varied distinctively over this
time.

3. Then, there was sufficient contact between the 2 populations - outside Africa - to allow for
'Neanderthal' genes
to get back into the Homo sapiens line.

BUT ... the mitochondrial evidence doesn't show any sign of this.

Not sure I am convinced yet ....

Subject: [DNA] 4 percent Neanderthal?

My question, to come, is driven by having a link to article on neanderthal genes in modern man not
functioning.

Which of the below is being suggested by some researchers:

A. 4 percent of modern humans show pieces of genetic material inherited from Neanderthals; or

B. The typical or average modern human (perhaps outside of sub-sahara Africa) shows 4 percent of
his/her genetic material inherited from Neanderthals; or

C. Something else

Have the pieces of genetic material alleged to be inherited from Neanderthal been associated with
any phenotype attributes? Or is it "junk" dna material, or control dna material?
