Question 1

Lamarckian Evolution

Answer 1

New organs or changes in existing ones arise because needs of an organism (giraffe example)

Question 2

Deme

Answer 2

Small populations in a locale (beavers in one portion of river)

Question 3

Phylogeny

Answer 3

Evolutionary relationships among all species alive today

Question 4

Convergent evolution

Answer 4

Two species from different ancestors develop similar traits (sharks and dolphins)

Question 5

Parallel evolution

Answer 5

Similar to convergent evolution, but a common ancestor between the species can be identified. The separation may be geographic

Question 6

Divergent evolution

Answer 6

Shared ancestor, but different traits due to environment (black bear, polar bear)

Question 7

Adaptive radiation

Answer 7

Emergence of number of lineages from a single ancestral species
(Darwins finch example)

Question 8

Niche

Answer 8

A distinct lifestyle, often Unimposing on competition

Question 9

Hardy-Weinberg equation

Answer 9

P+q=1,

Where p= dominant, q= recessive

Question 10

Genetic drift

Answer 10

Change in composition of gene pool due to chance

Question 11

Founder effect

Answer 11

Genetic drift

Question 12

Gene flow

Answer 12

Migration of individuals between populations

Question 13

Homologous structures

Answer 13

Same anatomical features and evolutionary origins (wings of a bat, flipper of a whale; forelegs of horse, arms of humans)

Question 14

Analogous structures

Answer 14

Similar function, different origin (bat wings and fly wings)

Question 15

Stanley L. Miller

Answer 15

Primordial soup experiment, 1953

Question 16

Coacervate droplets

Answer 16

Cluster of colloidal molecules surrounded by a shell of water - possibly led to formation of cells

Question 17

Primordial soup excluded which element?

Answer 17

Helium
