Yes, I know. This is evolution 101. Although it only needs a slight advantage/disadvantage to make a difference over evolutionary time. The foreskin got bigger and more complex in humans. There must have been some reason for this.
That is natural selection. It made us only able to have one child who had a 50% chance of inheriting it. If we'd been able to have more children, there would be more copies of it now. Instead, it came to an end with the first child who didn't inherit it.

Natural selection works by the number of offspring a trait enables you to have and to survive. Someone who can have 10 healthy kids has ten times the biological fitness of someone who can have one & passes on 10X as many copies of their fitter genes.
