Question

the theory of ______ states that organisms that are better suited for their environment will survive and reproduce, while those that are poorly suited for their environment will die off.

a. evolution by natural selection
b. survivalism
c. behavioral genetics
d. genetic mutation

Explanation:

Natural selection is the process by which organisms better adapted to their environment tend to survive and reproduce, while those less adapted die out. This is a key concept in the theory of evolution. Survivalism is not the correct term for this concept. Behavioral genetics focuses on the role of genes in behavior. Genetic mutation is a change in DNA sequence, not the overall theory described.

Answer:

A. evolution by natural selection
