Evolution

Question 1

Agents of Evolutionary Change

Answer 1

Overpopulation, Variation, Competition, Natural Selection, Inheritance of Variation, Evolution of New Species

Question 2

Speciation

Answer 2

Evolution of new species

Question 3

Isolation

Answer 3

No gene flow

Question 4

Phylogeny

Answer 4

Evolutionary History

Question 5

Convergent Evolution

Answer 5

Two species from different ancestors develop similar traits

Question 6

Parallel Evolution

Answer 6

A more recent ancestor between two species that develop similar traits

Question 7

Divergent Evolution

Answer 7

Species with a shared ancestor develop differing traits due to dissimilarities between their environments

Question 8

Adaptive Radiation

Answer 8

Emergence of a number of lineages from a single ancestral species

Question 9

Gene Pool

Answer 9

Total sum of alleles for any given trait in a population

Question 10

Hardy Weinberg Equilibrium

Answer 10

p + q = 1, P^2 + 2pq + q^2 = 1

Question 11

Hardy Weinberg Conditions

Answer 11

Large Population, No mutations, Random selection, No net migration

Question 12

Genetic Drift

Answer 12

Changes in the composition of the gene pool due to chance, are more pronounced in small populations (founder effect)

Question 13

Bottleneck

Answer 13

Large die-off events that cause genetic drift

Question 14

Amber

Answer 14

resin of trees

Question 15

Petrification

Answer 15

Minerals replace the cells of an organism

Question 16

Homologous Structure

Answer 16

Same basic anatomical features and evolutionary origin (i.e. Whale flipper, forelegs of horse)

Question 17

Analogous Structure

Answer 17

Similar function but may have different evolutionary origins (i.e. Fly wing, bird wing)

Question 18

Vestigial Structure

Answer 18

No known current function, but apparent ancestral function (i.e. appendix, tail)

Question 19

Primordial Soup

Answer 19

Methane, Hydrogen, Ammonia, Water
