DNA changes in hatcheries, interesting.

Man is a game changer.

We're a destructive force that completely changes our environment, both inadvertently and on purpose.

Nature has never seen anything like us, we bend it to our will rather than the other way around.

We don't even fully understand the effect our imprint has and will have.

Climate change is a good example or the aforementioned sun tan lotion creating changes in coral reefs.

It's hard to imagine that we haven't had a drastic effect on evolution since Darwins time.
