Question

Which of the following is TRUE?

a. Adaptation to the environment does not require heritable traits
b. Adaptations can either increase or decrease fitness in a given environment
c. Individuals with adaptations have higher fitness than those without the adaptation
d. A trait can be an adaptation regardless of its effect on fitness

Answer 1

The correct answer is option c. "Individuals with adaptations have higher fitness than those without the adaptation".

Step-by-step explanation:

In evolutionary theory, adaptations are defined as the development or modification of biological mechanisms that helps an organism to adjust to a new environment. A modification in an organism must be beneficial in order to be considered an adaptation. Therefore, individuals with adaptations have higher fitness than those without the adaptation, and a better chance to survive to new environments.
