Imagining that we evolve cooling fins on our head for better heat dissipation. We already have the fluid circulation system after all.

Many of us have evolved a lack of hair on our heads, that's a first step right?

And the rest of us are capable of removing our hair (at least temporarily).

"Did you shave your head?" "Yeah, I have a big math exam coming up, so you know, I'm pulling out all the stops"

Sweating, especially on our head, is an adaptation like that that many mammals do not have but we do.

The scrotum can rise or fall based on the need for cooling. Can we concoct the genes that would allow our heads+brains to do the same ?
