Answer

Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime—such as greater development of an organ or a part through increased use—could be transmitted to their offspring.

Lamarck believed that the stretching elongated the giraffe's neck, which became a useful characteristic and was passed onto future generations. This resulted in the length of the giraffe's neck increasing over time. It is now commonly accepted that Lamarck's ideas were wrong.

Answer:

C) specialists.

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.
