Front

What is a behavioral adaptation?

Back

A behavioral adaptation is an action or behavior that helps an organism survive, such as hibernation or migration.

Front

What are homologous structures?

Back

Homologous structures are similar structures in different species that have evolved from a common ancestor, indicating evolutionary relationships.

Front

What are vestigial structures?

Back

Vestigial structures are body parts that have lost their original function through evolution, such as the human appendix.

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

What is adaptation?

Back

Adaptation is a characteristic that enhances an organism's ability to survive and reproduce in its environment.

Front

What is variation in the context of evolution?

Back

Variation refers to the differences in traits among individuals in a population, which can lead to evolutionary changes.

Front

What is the significance of overproduction in evolution?

Back

Overproduction is when organisms produce more offspring than can survive, leading to competition and natural selection.

Front

What is an analogous structure?

Back

Analogous structures are body parts in different species that serve similar functions but do not share a common evolutionary origin.
