The Importance of Variations in Natural Selection

The video discusses the concept of variation, highlighting how traits differ within a population. It provides examples of variations in animals, such as differences in claws, swimming abilities, and jaw strength. The importance of these variations is emphasized in the context of natural selection, explaining how they contribute to the survival and evolution of species.

What are some of the traits that can vary among individuals in a population?

• Color and size

• Claws, swimming ability, and jaw strength

• Height and weight

• Diet and habitat

How is variation defined in the context of a population?

• As the genetic makeup of a species

• As the number of individuals in a population

• As the differences in traits or characteristics

• As the similarities between individuals

Which of the following is true about human variation?

• Human variation is not important

• Humans also possess variations

• All humans have the same traits

• Humans do not exhibit any variations

Why are variations important in natural selection?

• They have no impact on evolution

• They reduce the chances of survival

• They make individuals identical

• They help individuals survive and reproduce

What role do variations play in evolution?

• They hinder evolutionary processes

• They are the basis for natural selection

• They are irrelevant to evolution

• They make evolution slower
