Co-Evolution - Ch. 15

Question 1

Co-Evolution

Answer 1

Reciprocal evolutionary change between interacting species, driven by natural selection

Question 2

Evolutionary Speed Depends on:

Answer 2

Generation time
Population Size
Mutation Rate
Recombination
Genetic Architecture

Question 3

Mutualism

Answer 3

Describes a relationship between species in which both species benefit

Question 4

Commensalism

Answer 4

Describes a relationship between species in which one species benefits and the other is neither helped nor harmed

Question 5

Reciprocal Selection

Answer 5

Selection that occurs in two species die to their interactions with one another.

Question 6

Geographic Mosaic Theory of coevolution

Answer 6

The geographic structure of populations is central to the dynamics of coevolution.

The direction and intensity of coevolution vary from population to population, and coevolved genes from these populations mix together as a result of gene flow.

Question 7

Antagonistic

Answer 7

One species benefits from the interaction but this is harmful to the other species

Question 8

Coevolutionary Arms Race

Answer 8

When species interact antagonistically in a way that results in each species exerting reciprocal directional selection on the other.

Question 9

Mullerian Mimicry

Answer 9

When several harmful or distasteful species resemble each other in appearance, facilitating the learned avoidance of predators

Question 10

Batesian Mimicry

Answer 10

When harmless species resemble harmful or distasteful species, deriving protection from predators in the process
