- Global biodiversity - Wikipedia
Insects make up the vast majority of animal species [14]Chapman, 2005 and 2009 [9] has attempted to compile perhaps the most comprehensive recent statistics on numbers of extant species, drawing on a range of published and unpublished sources, and has come up with a figure of approximately 1 9 million estimated described taxa, as against possibly a total of between 11 and 12 million
- How many species are there on Earth? Progress and problems
This paper has since become the “default” estimate of the number of living species on the plant (8 75 million), even though approximately 80% of those species are hypothetical Here, I discuss why this paper represented important progress and how we might continue to move forward in estimating this fundamental number in science
- How many species are there? - Our World in Data
One of the most widely cited figures comes from Camilo Mora and colleagues; they estimated that there are around 8 7 million species on Earth today 4 Costello et al (2013) estimate 5 ± 3 million species; Chapman (2009) estimate 11 million; and after reviewing the range in the literature, Scheffers et al (2012) choose not to give a concrete
- How Many Species Are There on Earth and in the Ocean?
Assessment of this pattern for all kingdoms of life on Earth predicts ∼8 7 million (±1 3 million SE) species globally, of which ∼2 2 million (±0 18 million SE) are marine Our results suggest that some 86% of the species on Earth, and 91% in the ocean, still await description
- How Many Animals Are In The World In 2024
The Estimated Number of Described Species in the World Is 2 16 Million, and the Total Species Population Is 8 7 Million (IUCN) Of the 8 7 million species that exist on earth, we would probably consider 2 16 million species (2,153,938 exactly) to be animals; however, the other 0 3 million species are made up of living animals, too—such as
- Number of Species on Earth - Current Results
The greatest species diversity exists among insects, which account for about one million of the earth's species known to science Mammals make up one of the smallest groups, with just 5,513 members Altogether the earth's oceans, lakes, continents and islands support over 66,000 identified species of vertebrate animals and more than 307,000
- How many species are there on Earth? Progress and problems
How many species exist on Earth? Projections range from millions to trillions A 2011 paper in PLOS Biology provided a comprehensive estimate of 9 million
