Adaptive radiation
i just took the pennfoster test and the correct answer is, A adaptive radiation...hope i helped u out!!!
They are a classic example of adaptive radiation. Most of the animals on the Islands are from South America and came to the Islands, diversified into many species which inhabit different Islands in the chain. The finches and tortoises are the best example of this adaptive radiation; just evolution over time.
The finches beak sizes changed, depending on their environment and what kind of food they ate. The finches were relatively isolated on the islands, making them the perfect example of microevolution (change within a kind). This is not, however, evidence for macroevolution (change from one kind of animal to another), as the finches did not change into another animal, but simply had different sized beaks.
Galapagos tortoises eat grass and other plants which they acquire from grassy meadows.
The finches on Galapagos Islands. Marsupials provide another example.

The Galapagos finches were studied extensively by Charles Darwin and were instrumental in his theory of evolution. They show adaptive radiation, meaning they evolved to fit different niches in their habitat.
These special Birds called "Darwin's or Galapagos Finches" have special adaptations to various habitats were important evidence considered by Charles Darwin in formulating the theory of evolution; they are a striking example of adaptive radiation. They evolved because of their surroundings, the beaks their ancestors had couldn't function properly on the island.
Adaptive Radiation or Natural Selection (:
Darwin's finches were the result of adaptive radiation. One species coming to the Galapagos Islands radiated throughout all the Islands becoming many species fulling many different niches. Another example is the demise of the dinosaurs. Mammals radiated out from small, general beginnings to fill all the niches left by the extinct dinosaurs.

An example of adaptive radiation is Darwin finches, found in Galapagos Island. A large variety of finches is present in Galapagos Island that arose from a single species, which reached this land accidentally. As a result, many new species have evolved, diverged, and adapted to occupy new habitats. These finches have developed different eating habits and different types of beaks to suit their feeding habits.
Its the process where one common origin diverges into many different variations. For example. A finch from the mainland diverges into many types of finch on the galapagos islands due to different food sources. (large beak to break open seeds, narrow beak to eat grubs etc.)
Adaptive radiation is a rapid form of speciation that takes place when there is a mass immigration to new ecological niches, or a mass extinction of one dominant life form opening up niches for other life forms. Darwin's finches are examples of the former, as they reached the Galapagos Islands as one species and radiated from there into many different species of birds make there living in various ways that called for morphological changes, basically in beak size and shape. The death of the dinosaurs is an example of the latter radiation event. That is when several types of small mammals radiated out into all the niches left open bu the dinosaurs.
