Moderators, feel free to delete this if it's a repost- I'm sure it's been asked before somewhere in cyberspace (I'm new here- hi everyone). One thing I've been wondering about evolutionary development is how our current reliance on labor saving devices/technology/modern medicine will effect it. I assume humankind will (more than likely) never reverse directions in terms of developing advanced labor saving toys. If it continues for long enough- presumably for thousands of years, I'm thinking humans will eventually inherit certain dependancies or become specialized with certain things Since humans thrive using intellect, then one direction I predict would be further development of the brain. I wonder what will happen to everything else? I wonder if our limbs will eventually have characterestics that are suited for vehicles instead of walking/lifting objects? Will the immune system become reliant on medicine? Will the digestive system develop in such a way that it can only handle processed foods? What are your thoughts?
