|What we observe is increasing structuring of mammalin functions and bodies in the two poles. The head pole - responsible for individual orientation towards the world and the opposite pole responsible for reproduction.|
So the evolution of the descent of testicles into dangerous places outside of the body is directed by evolutionary forces that stand above random mutation and natural selection.

what about starfish? where are their poles?
And starfish are mammals too? What's your education?
Why do only mammals have "poles" VMartin?
Because reptiles and birds somehow do not have scrotal testicles outside their bodies. And that's why mammals are "only" Vertebrata having them. Just don't be afraid to use your logic.
Have I understood this correctly? Mammals have descended testicles because they have poles. Meanwhile, mammals are claimed to have poles because they have descended testicles.
Which comes first and why?
All sweeping statements are wrong.
