Evolution and Classification Review

A trait or change in lifestyle that helps a plant or animal survive in its environment

• adaptation

• evolution

• homologous

• vestigial

Organisms with the best suited adaptations for their environment are more likely to survive and reproduce than organisms that are not very well adapted

• natural selection

• artificial selection

• creationism

The diagram shows fossils in different rock layers. Which of these statements about the age of these fossils is most likely correct?

• Fossil A and C are the same age
  
• Fossil B is older than fossil C
• Fossils A is older than fossil B
• Fossil D is older than fossil C

What is an example of a vestigial structure of a HUMAN?

• Femur
• Wisdom Teeth
• Brain
• Finger

An anatomical feature that no longer seams to have a purpose in the current form of an organism

• Homologous structure

• Analogous structure

• Vestigial structure

• None of the above

Which best describes these structures?

• homologous

• vestigial

• analogous

What gives us our best evidence of evolution?

• fossil record

• law of superposition

• Pangaea

It can be concluded that animals with common anatomical structures

• evolved from a common ancestor

• belong in the same classification

• evolved from each other

• live in the same part of the world

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

The study of the early stages of development that is one evidence of evolution is:

• Homologous Structures
• Embryology
• Vestigial Organs
