BIOWhat is so special about Tropics??? O Speciation is generally a function of time Tropical latitudes remained undistributed for millions of years, so more evolutionary time for species diversity g action fo Tropical environments-less seasonal, more constant and predictable than temperate... V Such constant environments promote niche specialization and lead to a greater species diversity. More solar energy in Tropics, so higher productivity, more diversity.
