7A 9A HOMEWORK Exploring Evidence of Common Ancestry

Which of the following provides evidence of common ancestry among groups?

• Fossil record

• Biogeography

• Homologies

• All of the above

What does the fossil record primarily show?

• The geographical distribution of species

• The anatomical similarities between species

• The chronological sequence of life forms

• The molecular structure of DNA

Which type of homology involves similarities in the structure of different organisms?

• Anatomical homology

• Molecular homology

• Developmental homology

• Biogeographical homology

Biogeography is the study of:

• The distribution of species and ecosystems in geographic space and through geological time

• The molecular structure of DNA

• The fossil record

• The developmental stages of organisms

Which of the following is an example of molecular homology?

• Similar bone structures in the limbs of humans and bats

• The presence of similar DNA sequences in different species

• The fossilized remains of ancient organisms

• The geographical distribution of marsupials

Developmental homology refers to:

• Similarities in the embryonic development of different species

• Similarities in the adult anatomy of different species

• Similarities in the fossil record

• Similarities in the geographical distribution of species

Which of the following best describes anatomical homology?

• Similarities in DNA sequences

• Similarities in the structure of body parts

• Similarities in the fossil record

• Similarities in the geographical distribution of species

The presence of similar structures in different species that share a common ancestor is known as:

• Convergent evolution

• Divergent evolution

• Homology

• Analogy

Which of the following is NOT a type of evidence for common ancestry?

• Fossil record

• Biogeography

• Homologies

• Artificial selection

Which of the following statements is true about biogeography?

• It only studies the current distribution of species.

• It provides evidence for evolution by showing how species are distributed across different continents.

• It focuses solely on the fossil record.

• It is unrelated to the study of common ancestry.
