Very recently was some evidence pushing it back from 14k to 24k years before present http://nouvelles.umontreal.ca/en/articl ... n-thought/
100k years before present seems like a huge leap considering it was 65k years before present when modern humans are estimated to have left Africa. Homo erectus maybe though, but still seems unlikely because of temperature; I don't think there was a land bridge then but i am not sure
