Vestigial organs? Science has recently shown that the appendix is currently being used by our bodies. If I remember correctly, it is a repository for “good bacteria” that our intestines use to aid digestion.
It may have also been more utilized in the past, when the world didn’t have food preservation and refrigeration.
And how are male teats vestigial? That would imply that at some time in the past men, or male mammals, had functioning breasts! If that were so, then it would seem to me that we have “devolved”. That is to say, we’ve lost functionality we used to have.
What is more logical is the thought that the only thing that makes men male is the Y chromosome. We have all the code in our male bodies to product female offspring (the X chromosome), and that code gives us teats.

None of which changes my answer. To “devolve” is a value judgment. To “evolve” means to change. The fact you don’t approve of the change is irrelevant.
