This is a content request. I am intrigued by the moments in the ice ages when the land bridges closed to human transit. What would that experience been like for those crossing through Sundaland north of Australia or what would become Bass Strait or the Bering Strait or the English Channel. Those poignant moments of people realising they would not be able to return to the other side any more. How long might groups tried to get over and disappear and when would they learn it was no use trying. Then as time went on the new generations would only know of the other place through stories. Until they developed ocean going crafts. I would like to hear from historians or archaeologists working on this material.
Thank you
Bronte.
