>>34035007>becomes bipedal for no reasonBipedalism is the ultimate reason in and of itself. Quadrupeds are dumb, not physically, although not being able to grab things easily is stupid, but mentally dumb. Crows are by and larger smarter than almost every quadruped, dolphins are the anti-quadruped with no legs at all and those smart motherfuckers would be able to calculate the best way to rape your dumb dog at the beach when it goes out for a swim.
Bipedal evolutions of quadrupeds are simply evolving into superiority.
