Answer 1

One thing I haven’t seen mentioned in the answers is that to have all this intelligence takes a lot of calories. The brain burns 320 calories a day in the average person. That means that in order for our species to survive in the hunter/gatherer phase, we needed to cut energy demands elsewhere. Having the muscle structure of a lion or bear would have required more calories and then our brains would have evolved differently, with less horsepower for thinking.
