21 Which of the following is an example of founder effect:

A A species of darker-colored mice survive predation from owls & falcons, causing the population as a whole to shift to a darker color.

B A group of migratory birds stop on an island and never leave. They cease their migration & evolve into their own species.

C A group of horses with long necks randomly survive a brush fire that wipes out much of the population. These long-necked horses eventually evolve into giraffes

23 Which of the following is an example of macroevolution:

B Over many generations an off-shoot of catfish changes from a bottom-feeder to an aggressive hunter, no longer able to reproduce with the former catfish

C Over many generations a species changes in size from large to small to better fit in with the environment

D Over many generations a species of fish changes its scale color from yellow to blue

24 Consider a coral reef in the Atlantic Ocean: a species of clown fish are known to live all throughout this reef. During fishing season a large trawling net smashes the reef into three small pieces, all of which are separated by a large distance. After many generations the clown fish on the three different sections of reef become different species. This is an example of:

A Allopatric speciation

B Sympatric speciation

C Parapatric speciation

D Convergent speciation
