Understanding Evolution and Its Principles

What is the definition of evolution?

• The process by which organisms change over time as a result of changes in heritable physical or behavioral traits.

• The process by which organisms remain the same over time.

• The process by which organisms are created from non-living matter.

• The process by which organisms lose their ability to adapt.

Which finger of evolution is represented by the introduction of new genetic material into a population?

• Mutation

• Gene flow

• Genetic drift

• Natural selection

What role does mutation play in evolution?

• It decreases genetic diversity.

• It introduces new genetic variations into a population.

• It eliminates harmful traits from a population.

• It prevents any changes in a population.

Which of the following best describes the concept of natural selection?

• Survival of the fittest, where only the strongest individuals survive.

• The process by which individuals with advantageous traits survive and reproduce more successfully.

• The random change in allele frequencies in a population.

• The introduction of new genetic material into a population.

Using today's notes what is a change in the gene pool of a population from generation to generation called.

Which of the following scenarios best illustrates the concept of gene flow?

• A population of wolves becoming isolated on an island.

• A group of birds migrating and breeding with a different population, introducing new alleles.

• A species of fish developing a new color pattern due to mutation.

• A population of insects experiencing a sudden decrease in numbers due to a natural disaster.

Using today's Notes Match the following terms.

• Change in DNA

• Evolution

• Change over time

• Gene Flow

• Leads to adaptations

• Mutation

• is a random change in the frequency

• Natural Selection

• Individuals moving in and out of an area

• Genetic Drift
