On All Species Day

Looking back and looking forward to the challenges of affirming and protecting diversity of life in the midst of the "Sixth Extinction"

In the city of 'Santa Fe' named in memory of the 'holy faith' of St Francis, the patron saint of animals and ecology

History of the concept

The early Greeks and Romans had a well established set of taxonomic names for species of animals and plants, based upon the macroscopically observable characteristics of organisms, with Aristotle being the chief architect of this codification; even earlier, the Egyptians and Cretans developed basic symbols and names for species important in farming and culture. It was not until the year 1686 when English naturalist John Ray introduced the concept that species were distinguished by inevitably producing the same species, though considerable morphological variation was observed within a species.[1] Carl Linnaeus (1707–1778) formalized the taxonomic rank of species, and developed the two part naming system of binomial nomenclature that survives to current times, with genus and species names in Latin form.

Estimation of species numbers

Since most of the planet's species are deemed to be undiscovered, it is exceedingly difficult even to estimate the total number of species on Earth. An 2011 innovative study estimated the total number of species to be about 8.7 million, with around 86 percent of which are presently undiscovered.[2] The following represents a rough approximation of the number of species by taxonomic group, with ranges given for varying estimates of the species total numbers:

Total species: 7,000,000 to 100,000,000 (the lower number reflecting described species and the higher based upon estimates of Earth's species):

Bacteria: 5,000,000 to 10,000,000[3]

Archaea: 20,000 (based upon only marine species) [4]

Eukarya: 1,660,000

Of the described eukarya species 1,600,000 based on described species, including:

297,326 plants, including:

15,000 mosses

12,000 ferns

1,025 fern allies

980 gymnosperms

258,650 angiosperms

199,350 dicotyledons

59,300 monocotyledons

9,671 red and green algae

2,849 brown algae

100,000 fungi (of an estimated total 1,500,000 other non-animals) including:

25,000 lichens,

16,000 mushrooms

30,000 red, brown and blue-green molds

17,000 conidial fungi

1,260,000 animals, including:

1,203,375 invertebrates:

950,000 insects

81,000 mollusks

50,000 crustaceans

2175 corals

130,200 others

59,811 vertebrates:

29,300 fish

6199 amphibians

8240 reptiles

9956 birds

5416 mammals
