Q: What is it called when organisms with traits that better enable them to adapt to their environment tend to survive and reproduce in greater numbers?


Read this paragraph and choose the correct option from the provided answers:

New species develop naturally through the process of natural selection . Due to natural selection, organisms with traits that better enable them to adapt to their environment will tend to survive and reproduce in greater numbers. Natural selection causes beneficial heritable traits to become more common in a population and unfavorable heritable traits to become less common. For example, a giraffe’s neck is beneficial because it allows the giraffe to reach leaves high in trees. Natural selection caused this beneficial trait to become more common than short necks.

 Choices:

- natural distribution

- adaptation
