Answers
These are process that describe the steps involved in evolution. The correct order is as follows:
Mutation ⇒ Reproductive isolation ⇒ Natural selection ⇒ Evolution
This is the order that these events take place to lead to a the end result which is evolution.
Mutations involve the change in the DNA material.
Reproductive isolation is where some species are prevented from interbreeding with the rest due to properties they have.
Natural selection is the process where organisms that are better situated to their environment are prone to survive and reproduce more.
Evolution is the term that refers the gradual changes and development of organisms.
A large population which has common gene pools happen to isolate into two, and a barrier separates them from joining.
They are often put in many situations where they will have to survive for their living according to the Darwinian theory of evolution.
They will thrive in those situations, reproduce & evolve where their genes are passed to the new offsprings.
In this Natural selection, the chosen 'traits' are the most favored.
