if the total # of species is 1,413,000 what % of the total would humans be alone?
Answers
Explanation:
More than 99 percent of all species, amounting to over five billion species,[7] that ever lived on Earth are estimated to be extinct.[8][9] Estimates on the number of Earth's current species range from 10 million to 14 million,[10] of which about 1.2 million have been documented and over 86 percent have not yet been described.[11] According to another study, the number of described species has been estimated at 1,899,587.[12] 2000–2009 saw approximately 17,000 species described per year.[12] The total number of undescribed organisms is unknown, but marine microbial species alone could number 20,000,000.[12] The number of quantified species will ipso facto always lag behind the number of described species, and species contained in these lists tend to be on the K side of the r/K selection continuum. More recently, in May 2016, scientists reported that 1 trillion species are estimated to be on Earth currently with only one-thousandth of one percent described.[13] The total number of related DNA base pairs on Earth is estimated at 5.0 x 1037 and weighs 50 billion tonnes.[14] In comparison, the total mass of the biosphere has been estimated to be as much as 4 TtC (trillion [million million] tonnes of carbon).[15] In July 2016, scientists reported identifying a set of 355 genes from the Last Universal Common Ancestor (LUCA) of all organisms living on Earth.[16]
