Document Summary
Terry erwin found a certain number of species on earth and used that to estimate the total number of species on earth (between 30 to 100 million species on earth). Model a: 3. 7 million and model b: 2. 5 million. There are 2/3 arthropods still waiting discovery: mora in 2011 estimated the total number of species to be about 8. 7 mullion species. Theres a correlated pattern where they can estimate the total number of species in any one taxa. Today its try and figure out how many years it will take to describe all these species. Hamilton: 3. 7 million (would take 600 years to discover all species) Erwin: 30 million (would take 1400 years to discover all species) **know for test (would take 4800 years to discover all species) Take the __ million and divide by 6200 (which is the number of species discovered each year)
