Give three hypotheses for explaining why tropics show greatest levels of species richness.
1. Tropical latitudes have remained undisturbed for millions of years and thus, had a long evolutionary time for species diversification.

3. There is more solar energy available in the tropics, which leads to more productivity and hence species diversity.
