Among ancient members of the genus homo, a shift to a diet focused on meat-eating required new skills and created new challenges for our ancestors around 2.5 mya. explain why this diet created new challenges to the reproductive success of our ancestors, and describe at least one adaptation that spread in order to overcome these challenges.

The meat diet is really hard in the wild, because when you haunt animals these have adaptations that allows them to run away from the place, also are other predators doing competition for a same prey. If you used to take your food from plants change to take your food from animals is a huge change.

The reproduction in every species is different, in the genus Homo usually the females are taking the male with more fitness, fitness is in biology an expression of good food, protection, and a good life. The change of the diet, made more difficult the food taken, so the males had to effort double and sometimes asociate with other males to obtein preys. It wasn't easy to take the same fitness that they have with the plants.

one visible adaptation are the four fangs in our jaw. Those fangs allows to tear the skin and the meat easily, which give us advantage at the eating meat time.

In conclusion: the new diet reduces the capacity for taking food, taking food is a quality that female needs in a male, so while the most meat you get, the most succes you have in the reproduction.

one adaptation to the meat eating challenges are the four fangs.
