Question

3. Provide an example of speciation and how it occurred.

Answer 1

The classical example of speciation involving the interplay of complex forces such as isolation, competation, adaptaion etc leading to adaptive radiation at the species level is provided by Darwin finches.

Often happen when organisms enter environments with unoccupied niches, such as a newly formed lake or an isolated island chain and also because of lack of resources and space.

Finches isolated from eachother beacuse of ocean they have different beak structures based on the type of food they eat eg: blunt beaks to crach hard shell and medium beak to feed on insects.
