except your argument was that they traveled north based solely on skin sensitivity issues:
you're not very good at following your own chain of thought, are you?
Silly me, I'd thought you'd take it as A reason (major or otherwise, though I'd like to think it's a big reason) like any sensible person would and not THE and ONLY reason, and that I was just giving a super-summary and not the entire explanation of the whole thing.
last time i checked, most houses don't have wheels under them for moving purposes. the very ideea of a house implies that the place of residence is vewed as a permanent base of operations. animals of the migration sort don't have such a thing.
Humans started out living in caves and temporarily shelters to accompany their hunting and gathering lifestyle, so no, houses don't move you're right, but people do, and we sure as hell weren't living living in houses 100,000 BC. And the reason to why shelters were temporary with hunting and gathering is because resources while renewable, is still limited by its "cooldown", hence sooner or later you would deplete most of the useful stuff in the region for the moment and so you would have to move somewhere else; or maybe there were external threats from climates to different tribes to predators within the region that forces you to move, doesn't matter; it's not sensible to assume that living in the wild as a primitive human in those times has the same amount of safety and protection and access to good stuff as your good neighbourhoods today.
Also, hunting animals like lions have temporarily base of operation too, just like primitive humans did. But then again, neither of which are hardly "home keepers" or strangers to migration.
Point is, if humans started out instinctively to live by hunting and gathering, which involves periodic and sometimes frequent migration, before systematically utilising their intelligence to develop agriculture hundreds of thousands of years later, on what ground to you make the claim that we "don't have such a thing (migration instinct)".
