Species diversification requires a fairly suitable and sustainable environment for the species to live and thrive. Environmental stress will result in less species diversification and survival. As tropical regions have the same environmental conditions from a length of time they have more widespread species diversion and more amount of species as compared to the temperate region as they have hard life conditions and severe temperature fluctuations. Temperate regions underwent glaciations that lead to destructions.
So, the correct option is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'
