I have seen videos of small turtles going really fast on tiny skateboards. All of a sudden, they become a fast animal and seem happy with it. A bit like human with a bike or a car.

Feels like evolution is not as perfect as we want to believe sometimes.

Could something similar happen with sloths? Maybe their eyesight would improve quickly?

Who has ever said that evolution is perfect?
