Evolution Quiz

What is speciation?

• Formation of a new species from unrelated organisms

• Formation of a new species from a different phylum

• Formation of a new species from a different kingdom

• Formation of a new species from a common ancestor

What is a common ancestor?

• An extinct species with no descendants

• A species that evolved independently

• A species of organism from which one or more new species evolves

• A species that is not related to any other species

What is the best evidence for evolution?

• Fossil Record

• Molecular Similarities

• Anatomical Homologies

• Biogeography

What do vestigial structures indicate?

• Structures that are inherited from a common ancestor but serve no actual purpose

• Structures that are similar in shape amongst related species

• Structures that serve the same purpose in all species

• Structures that are unique to each species

What is the study of similarities in physical traits between different species called?

• Molecular Homologies

• Developmental Homologies

• Anatomical Homologies

• Biogeography

How can the age of fossils be determined?

• By studying the geographical location

• By examining the rate of decay of isotopes

• By observing the behavior of living organisms

• By analyzing the DNA sequences

What do molecular homologies indicate?

• Similarities in development of offspring

• Preserved remains of ancient species

• Similarities in physical traits between different species

• Similar DNA and Amino Acid sequences shared by species

What is the study of where organisms live now and where their common ancestors lived in the past called?

• Developmental Homologies

• Molecular Homologies

• Anatomical Homologies

• Biogeography

What do homologous structures indicate?

• Structures that are similar in shape amongst related species

• Structures that are inherited from a common ancestor and serve a specific purpose

• Structures that serve the same purpose in all species

• Structures that are unique to each species
