> plenty of non-jews have sloped foreheads yes, plenty of non jews carry neanderthaloid dna as well. also, neanderthal is not the only subhuman which has unfortunately carried its dna to modernity. and yes, jews are not neanderthals. they are a parasitic devolution of neanderthal because the neanderthal accumulated too many deleterious alleles and had to start interbreeding with other hominids to keep those alleles heterozygous.   al_genetics_of_jews#genetics_of_jew ish_populations > most populations contain hundreds of alleles that could potentially cause disease, and most people are heterozygotes for one or two recessive alleles that would be lethal in a homozygote. although the overall frequency of disease-causing alleles does not vary much between populations, the practice of consanguineous marriage (marriage between second cousins or closer relatives) has been common in some jewish communities, which produces a small increase in the number of children with congenital defects.
