I believe they were talking about mitochondrial DNA, and found no evidence of interbreeding, Studies of other parts of the DNA show substantial evidence of interbreeding. I think mitochondrial has some unique properties with respect to ancestry that should be considered when analyzing ancestral interbreeding.

Mitochondrial DNA is passed directly from mother to child, with no contribution from the father's DNA. The DNA in the nucleus is half from the father, half from the mother. If no Neanderthal mitochondrial DNA is found, that indicates that any inter-racial mating involved Neanderthal men mating CroMag women (or at least, mating which resulted in surviving progeny).

I think that means the neanderthal males bred with the homo sapien females since the mitochondrial DNA is passed through the females. 77 posted on Wednesday, by ckilmer

Yes. It seems the Cro Mag ladies returned to their Cro Mag families after the (perhaps involuntary) experience, and if any vice versa matings occurred, the Neanderthal ladies did not join Cro Mag.
