Aren't we getting weaker too? Something like the grip strength of humans who were hunter gatherers far exceeded modern day?

If so it's like we're redoing our fallout built and moving stats from strangth into intelligence

Our brains are smaller too tho. Our jaws are also getting smaller and weaker. Kinda like wolf to dog transition. We are kinda domesticating ourselves and I doubt we are actually smarter now.
