How does evolution explains complex courtshiping?
It always confused me how some of those extremely complex and convoluted courtship methods would evolve naturally. It is mostly seen on birds, but not only on them. In many cases is not learned, It is instinctual. So how?
Is not something as straightforward as, "new generation has hotter bodies so they are better adapted to the increasing cold temperatures, so they have better chances of surviving and reproducing".
