Evolution & Biology Vocabulary Flashcard

Front

What is evolution?

Back

Evolution is the process by which organisms change over generations due to genetic variation and natural selection.

Front

What is a scientific theory?

Back

A scientific theory is a well-supported explanation based on evidence and observations.

Front

What is a fossil?

A fossil is the preserved remains or traces of ancient organisms.

Front

What is natural selection?

Back

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

Front

What is artificial selection?

Back

Artificial selection is the process of humans breeding organisms for specific traits.

Front

What is genetic variation?

Back

Genetic variation refers to the differences in DNA among individuals within a species.

Front

What is adaptation?

Back

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

Front

What is the role of mutations in evolution?

Back

Mutations are changes in DNA that can lead to new traits, contributing to genetic variation.

Front

What is the significance of fossils in studying evolution?

Back

Fossils provide evidence of past life forms and how they have changed over time.

Front

What is the difference between natural selection and artificial selection?

Back

Natural selection is driven by environmental factors, while artificial selection is driven by human choice.
