NC Biology EOC Review: Evolution and Genetics

Front

What is the Fossil Record?

Back

The Fossil Record is a timeline of life on Earth developed from millions of fossils of different organisms.

Front

What is the selective agent in natural selection?

Back

The environment is the selective agent in natural selection.

Front

What are fossils?

Back

Fossils are the physical remains of a plant or animal preserved in rock or Earth's crust.

Front

What does variation mean in biology?

Back

Variation refers to genetic differences between organisms of the same species.

Front

Why are mutations important in evolution?

Back

Mutations are important because they bring about genetic variation needed for a population to evolve.

Front

What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

Define adaptation in the context of evolution.

Back

Adaptation is a trait that helps an organism survive and reproduce in its environment.

Front

What is genetic variation?

Back

Genetic variation is the diversity in gene frequencies among individuals within a population.

Front

What is the theory of evolution?

Back

The theory of evolution explains how species change over time through processes like natural selection and genetic drift.

Front

What role do mutations play in evolution?

Back

Mutations introduce new genetic variations, which can lead to evolutionary changes in populations.
