most intriguing to me was the discovery which even today some 00:23:13 archaeologists deny but the evidence is actually overwhelming that oceans were no barriers to erectus they sailed across oceans so this is a quote from a 00:23:24 very good book on Paleolithic Stone Age seafarers Paleolithic books our ancestors have often been painted as unintelligent brutes however this simply is not the case evidence suggests that at least homo erectus and perhaps even 00:23:37 pre erectus hominids were early seafarers based on this evidence it seems that our early ancestors were successful seafarers biological studies suggest that considerable numbers of founder populations so when we find 00:23:50 evidence of erectus tools on an island there had to have been 2250 erectus arrived they're more or less the same time it's not just that one erectus got there we also know and I'll go into this 00:24:03 that they didn't just wash ashore it would have been almost impossible some archaeologists suggest that they got there by tsunamis but when I talked to friends of mine who are earth scientists they say that's not how 00:24:17 tsunamis work you know the tsunamis are pushing water to land and it is possible that afterwards some things flow out but most of the energy is towards the land and it is true that a few animals have 00:24:30 made it but we don't find regular systematic colonization by humans waiting to ride tsunamis most people don't try to do that
