This isn't really surprising since studies have shown that thanks to things like tools and fire, humans are able to spend a lot less time eating and gathering food than most other animals do. Basically, because of those two things, we're able to 'pre-digest' food before we stuff it into our pie holes, which means we get more energy out of the food and we don't need to eat as much as other animals, so that gave us free time to think up things like twerking and the reverse mortgage.
