Given what we know about evolutionary biology, we expect to find the largest number of endemic species in which of the following geological features, which have existed for at least a few million years?
A) an isolated ocean island in the tropics
B) an extensive mountain range
C) a grassland in the centre of a large continent, with extreme climatic conditions
D) a shallow estuary on a warm-water coast

Question

Quizplus · Accepted Answer

Isolated ocean islands in the tropics are known to have a high number of endemic species because they are geographically isolated and have unique environmental conditions. This isolation allows for unique genetic diversification due to lack of gene flow with mainland species. Additionally, the tropical climate and complex topography create microhabitats that are suitable for a wide range of species to evolve and adapt to.
