Question

A. invasive

B. pioneer
C. generalist
D. specialist
E. soil former
More than one million years ago, a single species of finch migrated to the Galapagos from the mainland of Central or South America. From this one migrant species at least thirteen species of finch would eventually evolve. This process in which one species gives rise to multiple species that exploit different niches is called adaptive radiation. In describing the four different finch species we see here, we could also say that filling these varied niches would classify the birds as
A) generalists.
B) endemics.
C) specialists.
D) invasives.

Answer 1

C) specialists.

Step-by-step explanation:

The finches of the Galapagos Islands would be considered specialists. This is because the finches have diversified in a way in which each species has uniquely evolved to perform a very specific task (eating a particular type of food). Moreover, this process is known as adaptive radiation, as a single lineage (the original finch) undergoes speciation events that eventually fill divergent ecological niches, creating many related species.
