We know the cataclysms and as far as we know the disasterous one that almost wiped us out was when we were still in africa.
The ice ages might be called a cataclysm other than they lasted a very long time, and were more of a genenetic meat grinder.
During that period, europeans huddled in three small regions of mediterranean europe, and the remnants of those isolation events, and their northward migration following the retreat of the ice is still evident in the genetic record.
While the flooding of the mediterranean probably masked a good portion of the record of the evolutoin of our distant primate ancesors, as far as I know the flooding of the persian gulf and the black sea and doggerland as well as a host of other sites, especially in the south pacific, probably hid from us records of our past we would like to see.
But while caves make a good acheological source of materials, the rate at which our out-of-africa ancestors moved across terrain, prohibited them from anything like residency in caves, rather than say, seasonal use.
