Evidence of Ancestry

The image shows part of the humerus bone in different genera of primates. Which statement is best supported by the observable structures of the different humerus bones?

• the primates lived in similar environments

• the primates shared a common ancestor

• the primates interbreed with similar organisms in a population

• the primates had diets that consisted of similar types of foods

Cetaceans are whales and their relatives. The diagram shows some fossils of cetaceans. Which statement provides the best evidence that Ambulocetus natans is an ancestor of Basilosaurus isis?

• Homologous structures occur in each fossil

• Similar nitrogenous bases are found in the DNA of each fossil

• The fossils were found in different locations

• The youngest fossil is larger than the older fossils

Scientists compare the limbs of organisms to look for evidence of common ancestry. These limbs provide evidence of common ancestry because they -

• perform the same function
• are the same size
• have the same basic structure
• are parts of the same animal

A structure/organ in an organism that no longer has a purpose BUT had a purpose for the organism’s ancestors.

• Vestigial Structure

• Evolution

• Developmental Homology

• Structural Homology

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...

• homologous structures

• vestigial structures

• transitional fossils

• common ancestors
