Question 3

Fossil Record

Question 5

Anatomical Homology

Answer 5

structural similarities between different species like the bones in bird’s wing being similar to the bones in a human’s arm

Question 6

Embryonic Homology

Answer 6

describes the similarities in the pre-birth development in different species

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 8

Answer 8

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

Question 9

Common Ancestry

Answer 9

theory that all organisms descended from a mutual species

Question 10
