Evidence for Evolution Check for Understanding

Front

What is the evidence for evolution based on embryonic similarities?

Back

In the early stages of development, embryos of different species often look very similar, indicating a common ancestry.

Front

What is a vestigial structure?

Back

A vestigial structure is a body part that has lost its original function through evolution, such as the pelvis bone in whales.

Front

What does the fossil record indicate about the age of fossils?

Back

The fossil record shows that older fossils are typically found in deeper rock layers, while newer fossils are found closer to the surface.

Front

What type of evidence can DNA provide in the study of evolution?

Back

DNA evidence can show genetic similarities and differences between species, supporting the idea of common ancestry.

Front

Who is known for developing the theory of natural selection?

Back

Charles Darwin is known for developing the theory of natural selection after his observations in the Galapagos Islands.

Front

What is the difference between homologous and analogous structures?

Back

Homologous structures are similar due to shared ancestry, while analogous structures are similar due to convergent evolution, not common ancestry.

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 role do fossils play in understanding evolution?

Back

Fossils provide evidence of past life forms and their changes over time, helping to trace the evolutionary history of species.

Front

What is the significance of transitional fossils?

Back

Transitional fossils show intermediate forms between different species, providing evidence for the gradual process of evolution.

Front

How does comparative anatomy support the theory of evolution?

Back

Comparative anatomy studies the similarities and differences in the anatomy of different species, indicating common ancestry.
