Wolves, polar bears, and lions are some of Earth’s many hypercarnivores meaning that meat makes up more than 70 percent of their diets.

But tens of millions of years ago, mammals that mostly subsisted on flesh didn’t exist.

It took considerable time for mammals to evolve the right teeth and digestive systems to become hypercarnivores.
