Answer 1

Answer:

Survival of the fittest is the answer..

Answer 2

Answer:

Punctuated equilibrium was not included in Charles Darwin’s theory of natural selection. (Option b)

Explanation:

What do you mean by evolution?

• Charles Darwin defined evolution as "descent with modification," the idea that species change over time, give rise to new species, and share a common ancestor.
• He was the first person to propose evolution by the process of natural selection.

Natural selection

• Since resources are limited, organisms that have inheritable traits that favor survival and reproduction will reproduce and tend to leave more offspring than their peers, which results in an increase in traits over generations.
• Natural selection helps organisms to adapt to the environment over a period of time.
• The organisms that adjust to the environment in a better way will successfully survive and reproduce. This is called survival of the fittest.
• Overproduction in natural selection means each generation produces more than one offspring that can survive in an environment.
• As a result, the organisms start competing for natural resources like food, space, or light. This is called the struggle for existence.

NOTE

What is punctuated equilibrium?

• It is a theory that states species stay the same for a long period of time and the evolution of new species occurs suddenly due to global changes and mass extinctions.
• This theory is not the part of natural selection proposed by Darwin.
