Evidence of Evolution

Structures with the same parts have different functions; suggests that organisms

• are not related at all

• share a common ancestor

• share the same environment

• have the same fossil

Study of embryos of various organisms to show a common ancestor because of similarities in development

• natural selection
• embryology
• speciation
• evolution

Two organisms that are closely related would have

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

Which layer is the oldest

• B
• A
• E
• C

Which best describes these fossils?

• The oldest fossils can be found on the lower layers
• The oldest fossils can be found at the top layers
• The youngest fossils are always found on the bottom layers
• You can not tell the age of any of these fossils

If species A and B have very similar genes and proteins, what is probably TRUE?

• species A and B share a relatively recent common ancestor
• species A evolved independently of species B for a long period
• species A is younger than species B
• species A is older than species B

Individuals that are well adapted to their environment will survive and produce:

• Fewer mutations
• Stronger genes
• More offspring
• Better traits

If you are examining the structure and arrangement of the bones if different species you would be

• fossil record

• comparing embryology

• comparing biochemistry

• comparing anatomy

A fossil of an extinct 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 extinct 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

If I wanted to look at DNA to study evolution, I am using what evidence?

• comparative anatomy
• embryology
• fossil record
• molecular
