Approximately 8 million Species of Life

There are about 8.7 million (give or take 1.3 million) is the new, estimated total number of species on Earth — the most precise calculation ever offered — with 6.5 million species on land and 2.2 million in oceans. Announced by the Census of Marine Life, the figure is based on a new analytical technique. The number of species on Earth had been estimated previously at 3 million to 100 million.

That is a new, estimated total number of species on Earth — the most precise calculation ever offered — with 6.5 million species found on land and 2.2 million (about 25 percent of the total) dwelling in the ocean depths.

Announced today by Census of Marine Life scientists, the figure is based on an innovative, validated analytical technique that dramatically narrows the range of previous estimates. Until now, the number of species on Earth was said to fall somewhere between 3 million and 100 million.

Furthermore, the study, published by PLoS Biology, says a staggering 86% of all species on land and 91% of those in the seas have yet to be discovered, described and catalogued.

Says lead author Camilo Mora of the University of Hawaii and Dalhousie University in Halifax, Canada: “The question of how many species exist has intrigued scientists for centuries and the answer, coupled with research by others into species’ distribution and abundance, is particularly important now because a host of human activities and influences are accelerating the rate of extinctions. Many species may vanish before we even know of their existence, of their unique niche and function in ecosystems, and of their potential contribution to improved human well-being.”

“When applied to all five known eukaryote* kingdoms of life on Earth, the approach predicted:

  1. ~7.77 million species of animals (of which 953,434 have been described and cataloged)
  2. ~298,000 species of plants (of which 215,644 have been described and cataloged)
  3. ~611,000 species of fungi (moulds, mushrooms) (of which 43,271 have been described and cataloged)
  4. ~36,400 species of protozoa (single-cell organisms with animal-like behavior, eg. movement, of which 8,118 have been described and cataloged)
  5. ~27,500 species of chromista (including, eg. brown algae, diatoms, water moulds, of which 13,033 have been described and cataloged)


Considering the number of different species estimated to exist, and the few that have been catalogued, we have a long way to go to learn about all of them.

How long ago did live show up in the fossil record?

The answer is 3.9 billion years ago when simple life forms appeared and fossilized.

This timeline of the evolutionary history of life represents the current scientific theory outlining the major events during the development of life on planet Earth. In biology, evolution is any change across successive generations in the heritable characteristics of biological populations. Evolutionary processes give rise to diversity at every level of biological organization, from kingdoms to species, and individual organisms and molecules, such as DNA and proteins. The similarities between all present day organisms indicate the presence of a common ancestor from which all known species, living and extinct, have diverged through the process of evolution. More than 99 percent of all species, amounting to over five billion species,[1] that ever lived on Earth are estimated to be extinct.[2][3] Estimates on the number of Earth’s current species range from 10 million to 14 million,[4] of which about 1.2 million have been documented and over 86 percent have not yet been described.[5] However, a May 2016 scientific report estimates that 1 trillion species are currently on Earth, with only one-thousandth of one percent described.

3900–2500 Ma

Cells resembling prokaryotes appear.[24] These first organisms are chemoautotrophs: they use carbon dioxide as a carbon source and oxidize inorganic materials to extract energy. Later, prokaryotes evolve glycolysis, a set of chemical reactions that free the energy of organic molecules such as glucose and store it in the chemical bonds of ATP. Glycolysis (and ATP) continue to be used in almost all organisms, unchanged, to this day.


Religion and Life on Earth

Religion based on the Old Testament creation story, claims that all the millions of species of life – aquatic and terrestrial were created in three days of 12 hours each. So in 36 hours, all the approximately 8 million species and subspecies with different physiology and characteristics came into existence:

Creative Day Three – plants (approximately 298,000)

Creative Day Five – aquatic (approximately 2.2 million) and flying creatures

Creative Day Six – land animals (approximately 6.5 million including birds)  

Creative Day Six – man

As discussed on the page “Bible History and Real History”, all life forms (species and subspecies) appeared only six thousand years ago based on the genealogy or history of Adam.
