Not only is it more advantageous, it actually was force selected for (IIRC, poached elephants are often left for dead). So this is closer to selective breeding/artificial selection more so than natural selection.
When I think of selective breeding I think of humans picking out which animals (cows/dogs/wheat/etc) get to reproduce.
Probably because the concept of "nature" no longer serves any purpose if you don't, as it doesn't exclude anything.
It's often a pointless distinction to make (see also: anything that labels itself as "organic"), but it's a convenient shorthand to describe a category of interactions that people often want to talk about.
