A CHALLENGING PUZZLE: WHY HOMOSEXUAL ANIMALS?
By Renato Cocchi, MD
Three
years after the 1st edition, the book
Bruce Bagemihl: Biological exuberance. Animal homosexuality and natural
diversity. St. Martin's Press 2000 (
does not stop putting forward interesting problems.
When
more than 450 species have both males and females' homosexual members, we need
immediately to deny any genetic responsibility for it, because too many
variables into play.
Actions
of stress inside the uterus or inside the egg during a particular moment of
sexual differentiation of the embryo could have better explained it, but till
now there is not any confirmation.
