Question

Quizplus · Accepted Answer

India was a separate continent until 45 million years ago, which allowed for a unique set of plant and animal species to evolve in isolation from nearby southeast Asia. This is known as biogeographical isolation and can result in speciation and distinct evolutionary paths. This is further supported by the fact that India is known for its high biodiversity and endemism, with many species found only on the Indian subcontinent. The other options (A, B, C, D) do not adequately explain the drastic differences in species between India and southeast Asia.
