Question: Do you think knee caps and behinds are necessary? Serious question.

Without kneecaps we wouldn’t be able to bend our legs as much so walking and running would be more difficult. Some more basic animals don’t have kneecaps and their tendons attach the top of their leg straight to the bottom, whereas we have kneecaps as a kind of midway point!
I think sitting down would be quite uncomfortable without a nice cushioned behind!
