Reply to comment by avogadros_number in Bering Land Bridge formed surprisingly late during last ice age, study finds - By reconstructing the sea level history of the Bering Strait, scientists found that the strait remained flooded until around 35,700 years ago, not long before humans began migrating into the Americas by avogadros_number

They asked "Couldn't they have started when the gap was small, they may have had kayaks or other boats"

I simply responded to the notion that yes, they could have. If the idea of migrating thousands of miles via boat 10k years later is plausible then so too is traveling short distances 10k years prior. You have to assume that the formation of the land bridge didnt happen overnight and instead included a network of bergs, bays, ice sheets that allowed for migration via the sea vs land.

They may have started before it opened up entirely. There is the Kelp Highway Hypothesis that suggests a migration via water occurred
