So I don’t see why it would be rediculous for animal and plant life to cross it. It’s been done across the Panama isthmus and the Sinai peninsula, so why not across Berangia. A reconstruction of the sea-level history of the region indicated that a seaway existed from 135,000 – 70,000 BP, a land bridge from 70,000 – 60,000 BP, intermittent connection from 60,000 – 30,000 BP, a land bridge from 30,000 – 11,000 BP, followed by a Holocene sea-level rise that reopened the strait. So 12,000 years ago is about the latest that humans could cross over, not the earliest. In fact the earliest could be 70,000 years ago, much older than that 36,000 year old calander. Furthermore it is believed that there were multiple waves of migrations, not just one, and not all by land. It’s thought that some people starting around Japan followed the kelp forests up the Kuril Islands, across the Alutian Islands to Alaska, and down the coast to California. This would also explain how quickly humans propagated and colonized the Americas. People travel much faster and farther by boat than by walking. Also there have been migrations back to Asia, the Siberian Yupiks originated from Alaska and most likely crossed back to Asia about 3,000 years ago, if not earlier. The Inuits and their ancestors them selves arriving in Alaska as soon as 10,000 years ago, they are the last migration prior to the Europeans.
