A structure from a distant ancestor that no longer serves a purpose

• Vestigial Structure

• Analogous

• Reproductive Isolation

• Coevolution

Which of the following is an example of a vestigial structure

• Tail Bone

• Opposable Thumbs

• Heart

• Spine

Change over time in a population

• Evolution

• Natural Selection

• Genetic Drift

• Adaptation

Unrelated organisms develop similar characteristics

• Convergent Evolution

• Divergent Evolution

• Reproductive Isolation:

• Speciation

Natural selection gradually changes the average features of a species. This process continues long enough for a species to change into a new species and the original species become extinct.

• Gradualism

• Punctuated Equilibrium

• Speciation

• Convergent Evolution

Which of the following is NOT one of the 5 sources of evidence for evolution?

• DNA

• Comparative Anatomy

• Embryonic Development

• Fossil Record

• Weather Patterns

Same structure from common ancestor, different function

• Homologous

• Analogous

Where is the oldest fossil found?

• Top layer

• Bottom layer

• Middle layer

Different structure, different ancestors, same function

• Analogous

• Homologous

A physical adaptation where an organism blends in the environment for its survival.

• Camouflage

• Mimicry

• Hide and Seek

• Invisibility
