>>11549501>Please explain why a whale would have a pelvis>HUUR DUUR WE DONT KNOW DEREFOER EBOLUTION>NON NO NO U CANT SAY IF WE DONT KNO DEREFORE GOD BECUSS DATSSS IGNORANSE!!!!!!!!!It probably allows muscles to contract around a point which stiffens up the lower trunk of the whales body for the phallus to more steadily penetrate during copulation. Like if you had your micropenis on your abdomen you'd flex your abs to make your stomach tight instead of letting it wobble all over.
However, humans know very little about how large whale morphology interacts with the environment and have never even observed sperm whales mate (look it up). So it's incredibly naive, ignorant, and sheep like of you to assume there is no purpose for the pelvis and therefore must be evolutionarily classified as vestigial. But your an evolutioontioner so it's expected that you would be incredibly naive, ignorant and sheep like.
