The points of OB are well taken. If I may take a section of your metaphoric discussion of the Neanders, I would like to speak of them literally. I am not a genetic anthropologist but 30 years ago I saw an actual physiologic throw back of a Neander in Lackawanna NY. The brow, the nose, the body all were a dead ringer. It was so profound a sight I recall it clearly today. The individual was a ruddy caucasion in color and gentle in disposition.

I was wondering about the DNA traces of Neander in modern humans as a result of seeing this person.

A quasi related observation is that modern humans with one extra chomosome (downs syndrome) are the most gentle kind people I have ever met.
