We already did. Look at the state of animals today vs <1 mya. Bovines grown in unprecedented mass numbers to live short lives before slaughter. Wolves bred into an all new animal, friendly and helpful to the dominate species. Previously apex predators with claws, teeth, speed and strength, rendered extinct.
Sometimes I wonder if we are going to be the unkillable plague that takes over the universe. Or maybe we will dissappear in a blink. It's hard to know, we don't have any reference point except ourselves.
