plus if that's cold, with frozen glaciers as far as the eye can see, would you make a trip across the land bridge not knowing what was on the other side or if there even was another side?

think how incredibly brave or desperate you would have to be to make such a trip.

Well... I'm probably way wrong, but I understand the bridge is nearly melted at glacial minimums so maximums are the only time to make the jaunt?

I hunt and study arrowheads/artifacts, and I wonder if the strata of the 50-60K yo sites show that projectiles/spears were in use 24K-36K years ago. Supposing there were hyenas, big-ass bears and all patrolling the land bridge, humans might want to migrate there, possibly (correctly!) envisioning warmer climactic conditions. Packs of 40 hyena could only be handled with spears, at a distance, no mano y mano would work.

Put another way, maybe the hold-up was due to lack of throwable weapons and an efficient offensive hunting mentality??

The prospect of 50,000 years of hyena progeny in a single cave awes me. Wow. Wonder if we can find a photo of that.

Yeah, if the hyenas were after me ....

Or religious.

Or, they might not have understood what a "peninsula" was. They would have assumed they could follow a coastline indefinitely. It's not like they had a birds-eye view of the world. If their culture was migratory, they might not have questioned why they wanted to keep moving.
