EVIDENCES OF EVOLUTION

Front

Two organisms that are closely related would have:
- very similar DNA sequence
- exactly the same DNA sequences
- no proteins in common
- completely different DNA sequence

Back

very similar DNA sequence

Front

The arm of a human, the flipper of a whale, and the wing of a bat all have similar bone structures. Therefore, these parts of the body would all be considered...

Back

homologous structures

Front

The two most important things that the fossil record tells us about the history of life on Earth are...

Back

some species go extinct, and new species appear over time

Front

A bird's wing and a butterfly's wing have the same function, but they have very different structures. These structures are classified as:

Back

analogous structures

Front

The process by which populations slowly change over time is called

Back

evolution

Front

Which of the following would be an example of homologous structures?

• the trunk of an elephant, the snout of a pig, and the nose of a dog
• the wings of a bat and the wings of a butterfly
• the tail of a dolphin and the hump on a camel’s back
• the arm bones of an ape and the front leg bones of a horse

Back

the arm bones of an ape and the front leg bones of a horse

Front

Similarities between different species are evidence of what, according to evolutionary biologists?

Back

The presence of a common ancestor in a species

Front

The tail bone, wisdom teeth, and appendix are all parts of the human anatomy that would be considered..

Back

vestigial structures

Front

If species A and B have very similar genes and proteins, what is probably TRUE?

Back

species A and B share a relatively recent common ancestor

Front

• The Fossil Record
• Embryology
• Comparative Anatomy
• Cosmology
