What is so special about tropics that might account for their greater biological diversity?
The specialty about tropics that might account for their greater biological diversity is as follows: a) Speciation is a function of time, unlike temperate regions which are subjected to frequent glaciations in the past, tropical latitude has remained relatively undisturbed for millions of years and thus they had a long evolutionary time for species diversification. b) Tropical environments are less seasonal, more constant, and predictable too. c) More solar energy is available in the tropical region is contributing to high productivity which is leading to greater diversity.
