Question

A central tenet of Darwin’s theory of evolution:

a. Biological evolution is directed; species actively develop strategies for survival—called adaptations.
b. Biological evolution is not directed; species do not actively develop strategies for survival—called adaptations.

Answer 1

A)

Explanation

The central tenet of Darwin's theory is that biological evolution is directed. It is the process by which the individuals of the species change their both heritable physical and behavioral traits over time. These changes lead to better adaptation to the changing environment and help in survival of the organism.

Answer 2

The right answer is B. Biological evolution is not directed; species do not actively develop strategies for survival- called adaptations.

Step-by-step explanation:

Darwin explains that more individuals are produced from natural selection and each generation of produced individuals can survive only if the inherit suitable phenotypic traits that fits the environment.
