Question

Millions of years ago, the ancestors of giraffes had short necks and used to eat leaves from the bushes on the ground. A

genetic mutation caused one giraffe's neck to be taller. This long-necked giraffe was able to eat leaves that were higher up on
trees. This gave it an advantage as it was able to access more food than other giraffes. Over millions of years, all of the
giraffes became long-necked. Which type of environmental factor caused this mutation to be inherited?

Answer 1

Answer:Natural selection.

It is the process by which certain traits become more common in a population over time. It occurs when individuals with certain traits are more likely to survive and reproduce than those without those traits. This leads to the traits becoming more common in the population over time. Natural selection is one of the main mechanisms of evolution.
