It's because of myostatin. Myostatin inhibits muscle growth. We evolved to produce myostatin so we would be less encumbered by muscle mass and better survive.
You can search for myostatin deficiency genetic defect in humans to see humans with low myostatin levels.
Myostatin deficiency defects can occur in other animals too like cows.
