Dodging Ice Ages ... in a Tipi

Something that's difficult to discern is the extent of glaciation as ice advanced and withdrew during the glacial periods in which Modern Man (i.e. Cro-Magnon) has been walking the Earth.  The movie view of things is that sort of thing was happening way back when Raquel Welch looked so hot in a fur swim suit in "1,000,000 B.C."

The actuality is the last major glacial advance was during the same period during which Indians have occupied America (i.e. roughly thirty thousand years).  There is some pride in telling you the last advance was called the Fraser glaciation (i.e. Pinedale).  So every Indian in Canada and a good bit of America either went South or died.  (Wiki:  Last Glacial Maximum)

The reason this is important to me is these glacial advances every time pushed all humans out of the way ... or killed them.  This has tremendous influence on the migration of humans about the planet and thus determined what we are in terms of ending up in different regions and growing different cultural identities, etc.

The main point is that Ice Ages seem like ancient history but they're not.  An actual Ice Age goes on for millions of years but the periods of glaciation within them are much more frequent.  Since Modern Man has existed for at least one hundred thousand years, these periods of glaciation have had a very large effect on our cultural evolution by pushing us this way or that and killing off those who couldn't hack it.

Perhaps interesting to you is the reverse effect on Africa and Asia as the ice didn't advance anywhere near as far.  Seemingly there were tremendous influences on migration in Europe and north America but not so much elsewhere.

The reason this bugs me is that we have at least one hundred thousand years of history and yet we only have the faintest clues of what was happening going back to the Altamira cave paintings from thirty thousand years ago.  There are traces from about thirty thousand years ago in Greece as well.  There are other faint traces but all seem to tap out about thirty thousand years ago.

So what happened to at least seventy thousand years for which there appears to be little or no trace.  Are you really willing to believe that for seventy thousand years we just grunted at each other and chucked spears at sabre-tooth tigers.  They had the same intelligence as we as they're close to genetically-identical.  There is enough headroom during that period to build Atlantis, destroy it, and forget all about it ... and do it several times over.

It's not my purpose to justify Atlantis but rather to get a perspective on the immense period of time in which we, given the lack of evidence, did almost nothing.  When we have done so much, whether positive or negative, in the relatively short period since then tells me it's impossible so much time could have passed in which we accomplished nothing.
