Fossils provide a historical record of life and show changes in species over time.

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 role does DNA play in understanding evolution?

Back

DNA sequences can show genetic similarities and differences among species, indicating evolutionary relationships.

Front

What is embryology?

Back

The study of embryos and their development, which can reveal evolutionary relationships.
