Question 2
Which of the following is an example of how biogeography can
lead to the formation of new species?
A
A population of birds on an isolated island develops
distinct physical characteristics over time.
B
C
A group of monkeys in a rainforest adapts to a chang-
ing climate by altering their feeding habits.
A herd of deer migrates to a different region and un-
dergoes genetic changes.
D
Two species of fish in neighboring rivers display similar
behaviors due to their shared ecological niche.



Answer :

Final answer:

Allopatric speciation occurs when a population is physically divided, leading to new species through adaptive radiation, as evidenced by Darwin's finches on the Galápagos Islands.


Explanation:

Allopatric speciation occurs when a population of one species is physically divided into isolated subpopulations, leading to different selection pressures and eventual divergence, resulting in new species. One example of this is seen in the finches studied by Darwin on the Galápagos Islands, where a single seed-eating bird species evolved into multiple finch species adapted for different food sources, showcasing adaptive radiation.
