In case anyone is wondering about the size of the effect, https://www.nationalgeographic.com/animals/article/wildlife-... has the numbers. Before the war, 2-4% of female elephants were tuskless. Now 32% of newly born ones are.

So it's a significant change, but it's not like this property was coming out of nowhere. It started off about as common as humans having green eyes.
