4.2.2-.4 Causes of Extinction
... Rates of extinction are very difficult to estimate, because we don't even know within an order of magnitude how many species there are. Fossil records can reveal the average "lifetimes" of species, or how long different classes of plants and animals generally exist on the earth before going exti ...
