This is f***ery. Evolution takes hundred thousands of years. iPhones have existed for idk five years maybe? There's no way in hell the body reacts to that this quick. If we were using iPhones 10 hours a day for 10000 years, then our fingers would maybe change, but this is absolutely stupid. Sorry, but if you believe this...
This is BS. Evolution doesn't work this way... We don't just adapt to our surroundings, it has to do with survival and breeding... Who's gonna breed with that? That's a lot of mutation... And people won't evolve anymore because we adapt to our environment with our brains, not our bodies anymore. We create our own adaptations.
If we had a second ice age we wouldn't evolve to adapt, we would build technology to help us survive.
