Evidence for Evolution

What is suggested by the similarity of early embryos of different species of vertebrates?

• no evolutionary relationships between the groups
• recent common ancestry
• similar environments in the past
• evolution from a distant common ancestor

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

Two organisms that are closely related would have

• exactly the same DNA sequences
• no proteins in common
• completely different DNA sequence

What types of structures have the same parts but different functions and suggest that organisms share a common ancestry

• vestigial structures
• homologous structures
• analogous structures

• fossil

How do fossils provide evidence that evolution has happened on Earth?

• Fossils show how the sizes of certain animals has changed drastically over millions of years
• Fossils show that some species have gone extinct
• Fossils show the changes that living things have gone through over time.

• Different sedimentary rock layers provide evidence for how the environment has changed over time

What type of structures indicate that closely related species went through natural selection in different environments and under different selective pressures?

• analogous

• homologous

• vestigial

A fossil of a dinosaur is found and the anatomy of the fossil shows similarities to that of a bird. What could this mean?

• This is purely by chance and isn't significant
• The dinosaur and modern bird share a common ancestor

• All dinosaurs evolved into birds and that's why there aren't any dinosaurs alive today
• Dinosaurs choose to fly, and evolved into birds to escape predation and capture food

What type of structures indicate that species that are not related went through natural selection in similar environments with similar selective pressures?

• analogous

• homologous

• vestigial

Protein sequences in one organism that resemble those of another suggest a 

• coincidence
• lack of evolutionary relationship
• great number of mutations
• shared ancestry
