I don't think GP's comment shows the lack of understanding of evolution that you're trying to point out: numerous similar events occurring to a range of herds over a period of time is exactly how that would happen isn't it?

Not to say I agree (or not) this particular case would be effective, or that it's fine for man's influence to cause it, or anything. Just I don't think they showed any sign of thinking caribou would suddenly evolve like a Pokémon to have a stronger hoof or something.
