Both organisms' DNA is sequenced, and then compared to one another. The number of nucleotide changes is literally counted (though with a computer). It is an estimate because of genetic diversity within a species

Ecologists estimate the total number of species in the world using various methods, including extrapolation from known species counts, statistical modeling, and biodiversity surveys. They often utilize sampling techniques in diverse ecosystems to gather data on species richness, which can then be extrapolated to estimate total biodiversity. Additionally, molecular techniques and genetic analyses help identify cryptic species that may not be easily categorized through traditional methods. Overall, these approaches aim to account for both described and yet-undiscovered species.

Charles Darwin is the scientist who proposed the theory of evolution by natural selection in his book "On the Origin of Species" published in 1859.

There are around 10,000 living species according to scientist's estimates, making them the most varied tetrapod (having four appendages) vertebrates. Not all these species are described and the exact number is impossible to estimate because there is no clear cut definition of a species. Taxonomists are constantly redefining species and subspecies.

Figures vary greatly - a conservative estimate puts the number of individual species at around 2,500.
There are currently about 1.4 million identified animal species, and about 1 million of them are insects. Biologists estimate the number of animal species could be as many as 5 million.The total of living plant and animal species is estimated as 8.7 million species. This does not include bacteria which could number in the hundreds of millions of species and subspecies.

Although the exact number of centipedes on earth is unknown, there is an estimate of the number of species. Worldwide there are estimated to be about 8,000 species living today.
