 Well, if that wasn't what killed off the last of the mammoths, do we have any idea what was? Well, we still have a number of hypotheses, and one of them is humans arriving to the island, but we think we can exclude that. There's no sign that humans ever interacted with mammoths on Brangle. So that leaves us with a couple of other potential ideas. One could be a wildfire. It could also be a disease that came into the island and killed them off.
