BIO What is so special about Tropics???ON Speciation is generally a function of time o Tropical latitudes remained undistributed for millions of 1g years, so more evolutionary time for species diversity Tropical environments-less seasonal, more constant and predictable than temperate... Such constant environments promote niche specialization and lead to a greater species diversity.
