Evidence of Evolution

Front

What are homologous structures?

Back

Structures in different species that are similar due to shared ancestry, indicating a common evolutionary origin.

Front

What are analogous structures?

Back

Structures in different species that serve similar functions but do not share a common evolutionary origin.

Front

What is embryology?

Back

The study of organisms at the early stages of development, providing insights into evolutionary relationships.

Front

What is adaptation in the context of evolution?

Back

A trait that enhances an organism's ability to survive and reproduce in its environment.

Front

What does the fossil record provide evidence for?

Back

The fossil record provides evidence of past life forms and their evolutionary changes over time.

Front

What are vestigial structures?

Back

Body parts that have lost their original function through evolution, such as the human appendix.

Front

What is the significance of DNA studies in evolution?

Back

DNA studies help trace genetic relationships and evolutionary history among species.

Front

What is natural selection?

Back

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

Front

What is a common ancestor?

Back

An ancestral species from which multiple species have evolved over time.

Front

What is variation in a population?

Back

Differences among individuals in a population, which can lead to evolutionary changes.
