Evidence of Evolution

Front

What is the evidence of evolution?

Back

Evidence of evolution includes fossil records, genetic similarities, and anatomical structures that show how species have changed over time.

Front

What does it mean if two organisms have very similar DNA sequences?

Back

It indicates that the organisms are closely related and share a common ancestor.

Front

Which modern animal is most closely related to the toothed whale?

Back

The Baleen Whale is most closely related to the toothed whale.

Front

What is natural selection?

Back

Natural selection is the process where organisms with traits better suited to their environment are more likely to survive and reproduce.

Front

What happens to organisms with traits that are not suited to their environment?

Back

They are more likely to become extinct.

Front

What is a common example of natural selection in moths?

Back

In polluted areas, dark moths are more likely to survive than light moths due to better camouflage.

Front

What is a common misconception about DNA sequences in closely related species?

Back

A common misconception is that closely related species have exactly the same DNA sequences; in reality, they have very similar sequences.

Front

What role do fossils play in understanding evolution?

Back

Fossils provide physical evidence of past organisms and show how species have changed over time.

Front

What is the significance of genetic similarities among species?

Back

Genetic similarities indicate common ancestry and evolutionary relationships among species.

Front

How can scientists determine the evolutionary relationships between species?

Back

Scientists can analyze DNA sequences, fossil records, and anatomical features to determine evolutionary relationships.
