hmm, wonder how it compares to Inuit skeletons then, which appear to have adapted in that direction as well.
as far as interbreeding goes, I am reminded of a study done on male stickle-backs (fish the size of minnows) that showed that the longer they went without mating the more likely they were to attempt mating with things that looked less and less like female stickle-backs, even with sticks and the like (the study was joked about as a "we needed a study to determine
that?" kind of thing - fascinating why you remember some things eh?).
thus one can imagine (more or less) marginalized individuals of one or the other species engaging is such behavior.
