What is Species:
The term species comes from the Latin species, which means class, type, category or characteristic aspect. Therefore, a species is a set of people or things that are similar because they have one or more attributes or characteristics in common, which allow them to be classified in the same category.
In biology and taxonomy, the biological species is the set or natural population of individuals (human beings, animals, plants, minerals) that have similar or common characteristics and are capable of reproducing among themselves, creating fertile offspring, therefore they proceed of common ancestors.
For example, if two dogs of different breeds are crossed, they would have a fertile dog, while if a horse and a donkey are crossed, they would have a sterile animal called mule or mule, therefore, the horse and the donkey are two different species and not two races of the same species.
The species is a basic category of the classification of living beings, is part of the genus or subgenus and contains varieties or races. It is written with two words, the first is the name of the genus to which the species belongs, and the second is the specific name, for example, Homo sapiens or Praying mantis. There are several million different biological species in the world that are part of the biodiversity necessary for balance in the ecosystems of planet Earth.
The so-called endemic species or microareal species are those that only survive in a certain geographical location and are not found elsewhere outside of this location. These species are not necessarily rare, threatened or endangered species, although this is often the case. If an endemic species is transported to another site outside its natural range, it is called an exotic species.
