Question 0

Adaptation

Answer 0

Question 1

Natural Selection

Answer 1

Process by which organisms with a certain set of favorable traits survive and reproduce other individuals with the same set of traits.

Question 2

Fossil Record

Answer 2

Displays the variety of organisms that have existed over time, including change from ancient, simple organisms to more recent, complex organisms.

Question 3

Biogeography

Answer 3

Geographic distribution of organisms; species living within the same region are more likely to be closely related.

Question 4

Anatomical Homology

Answer 4

Structural similarity a between different species like the bones in birds wing being similar to the bones in a human arm.

Question 5

Embryonic Homology

Answer 5

Describes the similarities in the pre-birth development in different species.

Question 6

Molecular Homology

Answer 6

Refers to the common DNA patterns that exist between species; the greater the similarities in DNA, the more closely related two species will be.

Question 7

Evolution

Answer 7

Scientific explanation for the diversity we see on the natural world and how it has changed over time; natural selection is the action mechanism.

Question 8

Common Ancestry

Answer 8

Theory that all organisms descended from a mutual species.

Question 9

Diversity

Answer 9

The difference seen between individuals of the same species and between species themselves.
