Evidence for Evolution

Front

What is the Theory of Evolution?

Back

The Theory of Evolution explains how species change over time through processes like natural selection and common descent.

Front

How does embryology support the Theory of Evolution?

Back

It shows that different species have a common ancestor due to similarities in their embryonic development.

Front

What are homologous structures?

Back

Homologous structures are body parts in different species that are similar due to shared ancestry, even if they have different functions.

Front

What are vestigial structures?

Back

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

Front

What is the fossil record?

Back

The fossil record is a historical archive of life on Earth, showing how organisms have changed over time.

Front

What can fossils tell us about evolution?

Back

Fossils help scientists understand the kinds of organisms that lived in the past and how they evolved.

Front

What is a cladogram?

Back

A cladogram is a diagram that shows the evolutionary relationships between different species.

Front

Which two organisms have hair?

Back

Primates and Rodents.

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 a common ancestor?

Back

A common ancestor is a species from which two or more different species have evolved.
