What are analogous structures?

• Structures that are vestigial and no longer used

• Structures that are identical across different species

• Structures that are similar in structure due to a common ancestor

• Structures that perform a similar function but do not share a common ancestor

Which of the following is an example of analogous structures?

• Human hand and monkey hand

• Butterfly wing and bird wing

• Human teeth and shark teeth

• Bat wing and bird wing

What are vestigial structures?

• Structures shared with all living organisms

• Structures essential for survival

• Structures that once had a function but are no longer necessary

• Newly evolved structures

What evidence supports the idea that organisms with analogous structures do not share a common ancestor?

How does comparative anatomy provide evidence for evolution?

• By disproving the theory of evolution

• By proving that all organisms have identical anatomy

• By focusing solely on molecular biology

• By showing structural similarities and differences among species

Why are homologous structures important in studying evolution?

• They are unrelated to evolutionary theory

• They indicate a common ancestry

• They suggest that all species have the same DNA

• They show that species do not evolve
