Explanation:

The article is about the origin of iguanas in Fiji. Option D states a new theory explaining their existence there, which is central to the article's topic. Option A is about a desert iguana's adaptation (not relevant to Fiji iguanas' origin). Option B mentions extinct ancient iguanas in East Asia (not related to Fiji's iguanas).

Answer:

D. A new theory has been proposed to explain the existence of iguanas in Fiji.
