Lecture 27: Coevolution

Question 1

Define coevolution

Answer 1

Change in the genetic make up of one species in response to an evolutionary change in another species.

Question 2

Define batesian mimicry

Answer 2

mimicry in which an edible animal is protected by its resemblance to a noxious one that is avoided by predators.

Question 3

Befine mullerian mimicry

Question 4

Understand the coevolutionary arms race

Answer 4

“You have to run to stay in place”

Question 5

Concordant phylogenies and discordant phylogenies support or refute cospeciation?

Answer 5

• Concordant phylogenies supports co-speciation hypothesis

- Discordant phylogenies refutes co-speciation hypothesis
