evolution

Question 1

gradualism

Answer 1

evidence of evolution would show gradual changes to the population as you examined the different layers of the fossil record.

Question 2

punctuated equilibrium

Answer 2

Changes in the fossils of organisms would make a sudden appearance surrounded by periods of relative stability

Question 3

biogeography

Answer 3

species that live in the same area are
closely related, but some ancestors are found living far apart; Pangaea–>continents. This is why fossils found in western Africa (near the Atlantic coast) show similarities to fossils found in the jungles of South America in Brazil

Question 4

homologous structures

Answer 4

structures that have similar characteristics in their bone structures but diff functions

Question 5

analogous structures

Answer 5

similar functions but diff structures

Question 6

genetic drift

Answer 6

a change in the gene pool that causes the species to evolve change

Question 7

bottleneck effect

Answer 7

a disaster happens and part of the population dies resulting in genetic drift

Question 8

founder’s effect

Answer 8

a small portion of the population

leave the area and form a new gene pool

Question 9

gene flow

Answer 9

a change in the gene pool due to movement of organisms (migration). Birds and even people who move around spread their genes to new places.

Question 10

vestigial structures

Answer 10

not useful to the organism but was to the ancestor
