A new article published in Nature finds that human boners used to have bumps. Lead author Cory McLean of Stanford was studying chimp and human DNA when he came across sequences that had been deleted during human evolution, one of which made human penises naturally rougher and tougher than they are today.
Guess our female ancestors didn't like a bumpy ride
i kinda want to know what they mean by spines or bumps when they talk about chimps, but i don't want the phrase "chimpanzee penis" to ever be in my search history.
