according to sequencing of recently uncovered Neanderthal DNA, non Africans share as much as 1-4% of their genes with Neanderthals.
so that begs the question;
1) did Neanderthals have cognitive functions similar to ours?
2) could one give a neanderthal an MBTI type?
3) did the Neanderthals contribute any sort of cognitive abilties that were before not known to homo sapiens sapiens?
