<h3>What are species?</h3>
A species is a unit of biodiversity as well as the fundamental classification and taxonomic rank of an organism in biology. The biggest group of organisms in which any two individuals of the right sexes or mating types can conceive a fertile offspring, usually by sexual reproduction, is referred to as a species. A species can also be identified by its karyotype, DNA sequence, anatomy, behavior, or ecological niche. In addition, since fossil reproduction cannot be studied, paleontologists use the chrono species idea.
