Chapter 15- Intimate Partnerships

Question 1

Reciprocal evolutionary change between interacting species, driven by natural selection

Answer 1

Coevolution

Question 2

Selection that occurs in two species, due to their interactions with one another

Answer 2

Reciprocal Selection

Question 3

A theory that proposes that the geographic structure of populations is central to the dynamics of coevolution.

Answer 3

Geographic Mosaic Theory of Coevolution

Question 4

Species interact antagonistically in a way that results in each species exerting reciprocal directional selection on the other. as one species evolves to overcome the weapons of the other, it, in turn, selects for new weaponry in its opponent.

Answer 4

Coevolutionary Arms Race

Question 5

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

Answer 5

Mullerian Mimicry

Question 6

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

Answer 6

Batesian Mimicry

Question 7

An increase in genetic diversity causes by the heterogeneity of coevolutionary processes across the range of ecological partners

Answer 7

Diversifying Coevolution

Question 8

Mutualistic organisms that live within the body or cells of another organism

Answer 8

Endosymbionts

Question 9

an RNA virus that uses an enzyme called reverse transcriptase to become part of the host cells DNA.

Answer 9

Retrovirus
