How Many Species Are On Earth?
Scientists at Dalhouse University have a new prediction for the number of eukaryote species residing on Earth. If the numbers are correct, taxonomists have an elephantine amount of work to do to discover and catalogue the unknown organisms.
14.1 of eukaryotes on Earth are catalogued after 250 years of work by taxonomists.
Eukaryotes - organsims composed of cells with organelles contained in a membrane.
Predicted Eukaryotes: 8.7 million
What is Needed to Describe the unknown eukaryotes:
Number of eukaryotic species desribed per year: 6,200
Average number of eukaryotes described in a taxonomists's career: 24.8
Estimated cost of desribing a eukaryote $48,500 USD
