But given what happened to Greenloop, what if…what if…they weren’t just co-migrating along with us? What if they were hunting us? Isn’t that why we came over? Following the grazing animals across the Beringian land bridge? What if we were stalking the caribou while they were stalking us? It wouldn’t discount any of the adaptations, just give them a different purpose. Nocturnal hunting would catch us at our most vulnerable. Camouflage skills are ideal for an ambush. And broad running feet would give them the speed to chase us down.
