OMG POINTS!!!!!!!!!!! SO MANY!!! HURRY FOR 45 POINTS JUST READ AND ANSWER - NO STEALING OR I'LL REPORT!!!
Read the passage from Darwin's journal. We will now turn to the terrestrial species (A. Demarlii), with a round tail, and toes without webs. This lizard, instead of being found like the other on all the islands, is confined to the central part of the archipelago. . . . It would appear as if it had been created in the centre of the archipelago, and thence had been dispersed only to a certain distance. Some of these lizards inhabit the high and damp parts of the islands, but they are much more numerous in the lower and sterile districts near the coast. I cannot give a more forcible proof of their numbers than by stating that when we were left at James Island, we could not for some time find a spot free from their burrows on which to pitch our single tent. Like their brothers the sea-kind, they are ugly animals of a yellowish orange beneath and of a brownish red colour above: from their low facial angle they have a singularly stupid appearance. They are, perhaps, of a rather less size than the marine species; but several of them weighed between ten and fifteen pounds. In their movements they are lazy and half torpid. When not frightened, they slowly crawl along with their tails and bellies dragging on the ground. They often stop, and doze for a minute or two with closed eyes and hind legs spread out on the parched soil. What observation led Darwin to believe that the A. Demarlii is terrestrial? They slowly crawl along the ground. They weigh between ten and fifteen pounds. They have yellow-orange bellies. They are found only in the center of the island.

Respuesta :

I think the answer is D.

Terrestrial can mean something living on Earth. (THEY ARE FOUND ONLY IN THE CENTER OF THE ISLAND) can back up that they live on Earth.

(THE MEANING OF TERRESTRIAL)

For animal that live on LAND it means they live predominantly or ENTIRELY on LAND.

For aquatic animals

They live predominantly or ENTIRELY in the OCEAN.

More information:

The term terrestrial is typically applied for species that live primarily on the ground, in contrast to arboreal species, which live primarily in trees.

There are other less common terms that apply to specific groups of terrestrial animals:

Saxicolous creatures are rock dwelling. Saxicolous is derived from the Latin word "saxum," meaning a rock.

Arenicolous creatures live in the sand.

Troglofauna predominantly live in caves.

Answer:

They are found only in the center of the island.

Explanation:

The most convincing proof that this is true is that when Darwin compares this species of lizard to the others, he notes that they differ in their location in the center of the island.

Logically, it makes sense: if they live in the center, they must not need to live regularly in water, or else their habitat would be closer to the coasts.

The other answers are not features that would differentiate marine lizards, so D is correct.
