It's the albedo gene. Their genetic makeup is anticipating global warming climate change and increasing their reflectivity.
Yup, that's it.
Or maybe it's the camo gene. Their genetic makeup is anticipating global cooling climate change in order to match the oncoming snowstorms and glaciation.
Yeah, yeah, that's the ticket.
At least they're not turning grey from their volcano gene to match the ash fallout from the oncoming volcanos due to all the rapid heating and cooling of the earth.
