ludmilkaskok [199]

Species is the basic unit of classification denoted by a unique two-part scientific name.

<h3>What is meant by species? </h3>

Species is a name given to a group of organisms which have similar individuals. They are capable of reproducing among themselves and thus exchanging genes among themselves.

Species is the lowest of taxa and is thus the most basic unit of classification. Genus is the next taxonomic rank of the next taxa on the hierarchy of classification.

It is estimated that on earth, there are 8.7 million species living currently. This concept of species is from the times of Aristotle.
