Thanks to poaching, some (mostly female) elephants are evading them by becoming tuskless, as the poachers are effectively weeding out the members of the population who have the genes for tusks. Since they need tusks for defense and to dig, it goes without saying that this can cause problems.
It's sad that this is happening, but I cannot say I'm surprised, with the exception of how quickly this occurred. It just shows that the impact of poaching may significantly alter the traits of the surviving populations that may not be undone. It also shows how fast evolution can occur.
Anyway, I wanted to post about this because it is sad and interesting, but didn't think it would fit in any of the other threads.
