Question: Who developed the first widely used system for naming plants and animals?

Disambiguated questions and answers:
context: The first part of the name – the "generic name" – identifies the genus to which the species belongs, while the second part – the specific name or specific epithet – identifies the species within the genus. For example, humans belong to the genus "Homo" and within this genus to the species "Homo sapiens". "Tyrannosaurus rex" is probably the most widely known binomial. The "formal" introduction of this system of naming species is credited to Carl Linnaeus, effectively beginning with his work "Species Plantarum" in 1753. But Gaspard Bauhin, in as early as 1622, had introduced in his book "Pinax theatri botanici" (English, "Illustrated exposition of plants") many names of genera that were later adopted by Linnaeus.

He is known as the "father of modern taxonomy".[4]

content: The Bauhins, in particular Caspar Bauhin (1560–1624), took some important steps towards the binomial system, by pruning the Latin descriptions, in many cases to two words.[8]

long_answer: The individuals who introduced many names of genera that were later adopted in the first widely used system for naming plants an animals were Caspar Bauhin, who is known for pruning the Latin descriptions, and Gaspard Bauhin, who is known for his book Pinax theatri botanici that featured many names of genera that were later adopted by Carl Linnaeus. Carl Linnaeus is credited with the formal introduction of the first widely used system for naming plants and animals, as he was a Swedish botanist, zoologist, taxonomist, and physician who formalized binomial nomenclature, which is the modern system of naming organisms. He is known as the "father of modern taxonomy".
