Match the Evolutionary Concepts Correctly with the Descriptions or Examples

Question 61

Matching

Match the evolutionary concepts correctly with the descriptions or examples of the concepts. Matches are not necessarily equal.

Premises:

Responses:

the genitals of snakes are analogous to a lock and key mechanism- the "keys' will only fit in certain "locks"

temporal isolation

this type of isolation is most closely related to allopatric speciation

mechanical isolation

homozygous dominant black mice are camouflaged by dark rocks and homozygous recessive light-colored mice are camouflaged by light colored rocks. Heterozygous grey mice have no camouflage and are easily picked off and eaten by hawks.

exaptation

prairie grouse females choose males to mate with that have the most intricate dance and make the loudest thumping noise with their chests

gene flow

the migration of bison from one herd to another results in this

behavioral isolation

a small population of humans colonize a deserted island and most of them have attached earlobes. One hundred years later, the colony consists of 550 people all with attached earlobes.

sexual selection

the ear bones of mammals were adapted from the jaw bones of reptiles

founder effect

two species of hawk are able to mate successfully, but one hunts in the morning and the other hunts at night. Mating between the two species does not occur

directional selection

this type of isolation is most closely related to sexual selection

ecological isolation

genetic drift

disruptive selection
