B-LS4-1 Evidence of Common Ancestry Flashcard

Front

What role does DNA analysis play in supporting the theory of evolution?

Back

It reveals genetic similarities between different species.

Front

How does biogeography support the theory of evolution?

Back

It reveals that similar species are found in similar environments across the world.

Front

What is the significance of transitional fossils in understanding evolution?

Back

They provide evidence of intermediate forms between different species.

Front

What evidence supports that Ambulocetus natans is an ancestor of Basilosaurus isis?

Back

Homologous structures occur in each fossil.

Front

How does comparative anatomy support the theory of evolution?

Back

It reveals similarities in the anatomical structures of different species.

Front

Define common ancestry in the context of evolution.

Back

Common ancestry refers to the idea that different species share a common ancestor from which they have evolved.

Front

What are homologous structures?

Back

Homologous structures are anatomical features in different species that share a common origin but may serve different functions.

Front

What is the significance of genetic variation in evolution?

Back

Genetic variation is essential for natural selection, as it provides the raw material for evolution.

Front

Explain the concept of 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 is the role of fossils in understanding evolution?

Back

Fossils provide evidence of past life forms and show how species have changed over time.
