Question

Which one does not help in understanding evolution?

• A. Genetic variation
• B. Natural selection
• C. Embryogenesis
• D. Isolation

Answer 1

The correct option is D Isolation

For understanding Evolution, we consider-

Genetic variation- These are changes in genes that are heritable, which might become useful for some, who get better adapted with habitat.

Natural Selection- It is the process in which the individuals who are better suited for the environment leave behind more offsprings than the ones who are less suited. It is a key component in studying evolution.

Embryogenesis- It is the process and formation of an embryo. With the help of this, we're able to make links with different species on the basis of their embryos.

Isolation is an important component in the process of Speciation. It doesn't help in understanding evolution. Hence, Option D is correct.
