What sort of selection pressure decides that jumping is good for species survival while running isn’t? Isn’t quadruped running just all around more energy efficient?
In: Biology
Hopping is actually pretty efficient — look at kangaroos.
And evolution isn’t targeted towards a goal, it mostly works by concentrating any trait that improves an organism’s chances of leaving surviving offspring. A bunny ancestor successfully hopped away from a fox ancestor and bred more hoppy babies. Repeat for a few thousand generations, and you get bunnies.
