This would mean that if NA/SA didn't exist, Pangaea and all those other continents since (Laurasia, etc) would all be different, leading to massive butterflies. There's be species that aren't there in OTL, species wouldn't exist, humanity may not even exist, since then the KT extinction event would not happen, since the asteroid/meteor would land in the middle of the super-ocean, not in land.
