So is it only Professor Reiner Protsch von Zieten's dating of the Neanderthals that is called into question, or is it all other Neanderthal bones that have been found as well?
I'm not too sure that these new "dates" have held up; I think von Zieten had some other issues, legal ones, related to the sale of some bones. That's just from memory though, don't take my words as is. :')
