Assertion : Tropical latitudes have greater biological diversity then temperate latitudes. Reason : Tropical regions remain relatively undisturbed for millions of years.

Both assertion and reason are true Assertion is true but reason is false Assertion is false but reason is true Both assertion and reason are false

Both assertion and reason are true

Tropical latitudes have greater biological diversity. It is true. A forest in a tropical region like Equator has up to 10 times as many species of vascular plants as a forest of equal area in a temperate region like the Midwest of the USA. Speciation is generally a function of time and unlike temperate regions, subjected to frequent glaciations. In the past, tropical latitudes remained undisturbed for millions of years, where species continued to flourish.
