socalledrateswhat will the ideal human body be like?
Actual answer, there clearly isn't one ideal body type and that's good for the species. I like the show Physical 100 because it does a good job showing that.
Personal answer: imagine the peak performance of humanity if balls weren't on the outside!

Spermatogenesis would have evolved to work at internal body temperatures just like oogenesis has.
