What are homologous structures?

Back

Structures with the same parts that have different functions, suggesting that organisms share a common ancestry.

Front

What is evolution?

Back

The change in traits over time in a population.

Front

What is variation in genetics?

What are vestigial structures?

Body parts that have lost their original function through evolution.

Front

What is adaptive radiation?

The process by which organisms diversify rapidly into a variety of forms to adapt to different environments.

Front

What is natural selection?

Back

The process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is a mutation?

Back

A change in the DNA sequence that can lead to new traits in an organism.

Front

What is a fossil?

Back
