Halacha L'Maaseh for Gosse

According to Gosse and his supporters, do human remains which are dated as older than 6000 years convey tuma'as meis? Since they were just created as remains and never lived, I would assume the answer is no. This has practical ramifications for Kohanim who wish to visit museums containing prehistoric human remains.

If they do in fact convey tuma'as meis, what about other hominid species such as neanderthals?
