Actually not. If you start running regularly, which should have been a
common exercise for our ancestors, your butt will change noticeably to
keep up with the exercise.

Muscles on the back are not smaller or weaker than pectorals. They have a
different shape, but if you try to climb some tree or generally lift
yourself somewhere up, you'll notice that you need a lot of help from your
back. Pectorals are smaller in the vertical direction, because finding
good insertion points in a soft abdomen is going to be difficult. To
compensate for their shortness, they expand in volume and so are more
prominent.
