Questions and Answers

Why is genetic diversity important for evolution by natural selection to occur?

Genetic diversity is necessary for evolution by natural selection to occur because it allows for a greater chance of individuals having characteristics suited to environmental changes.

What is meant by 'selective advantage'?

Selective advantage refers to the characteristics that make an organism more likely to survive, reproduce, and pass on favorable alleles to the next generation.

How does natural selection drive evolution?

Natural selection drives evolution by selecting for organisms with variations that provide a better chance of survival and reproduction in a given environment.

What factors can lead to low genetic diversity in a population?

Low genetic diversity can be caused by very small populations or populations with a history of inbreeding. Signup and view all the answers

Explain the concept of 'speciation' in the context of evolution.

Speciation occurs when a population has no interbreeding with other populations, leading to the formation of a new species. Signup and view all the answers

What is the role of mutation in the process of evolution?

Mutation introduces new genetic variations, some of which may provide individuals with favorable alleles that increase their chances of survival and reproduction. Signup and view all the answers
