Evolutionary Relationships

Structures that are inherited from a common ancestor are homologous.

• True
• False

Humans, birds, whales, and lizards all have similar arm bones. What is the reason for this?

• The function of these bones is the same in all animals
• They live in similar environments
• They have a common ancestor
• All organisms resemble humans

Bird wings and butterfly wings are an example of

• Homologous structure
• Analogous structure
• Mimicry
• Camoflague

Analogous structures show common ancestry.

• True
• False

Which of the following pieces of evolution evidence deals with comparing similar structures in various species?

• fossil record
• comparing embryology

Some organisms that share a common ancestor have features that have different functions, but similar structures.  These are known as

• vestigial structures
• analogous structures
• homologous structures
• fossil structures
