Question 3

Biogeography

Answer 3

distribution of life on the planet

Question 4

Common Descent

Answer 4

organisms that have common ancestors

Question 5

Homologous Structures

Answer 5

have structures in related organisms that are similar in design, but may be different in function

Question 6

Homology

Answer 6

similarity resulting from common ancestry

Question 7

What are some examples of homologous structures

Answer 7

forearm, humerus, radius, ulna, carpals, etc.

Question 8

Divergent Revolution

Answer 8

the evolutionary pattern in which species sharing a common ancestry starts to become more distinct due to selection which leads to speciation

Question 9

Vestigial Structures

Answer 9

structures that have no apparent use in organisms, which served a purpose in its ancestors

Question 10

Common Embryology

Answer 10

embryos of organisms have similar traits implying that they are related

Question 11

Biochemical Structure

Answer 11

comparing DNA, proteins, RNA, etc. to determine evolutionary relationships
