The classification of living beings
Given the number of living beings in the world and their diversity, the taxonomy was created. This is the way that biology found to classify these beings and be able to study them. Therefore, it consists of a descending classification in:
- Kingdom;
- phylum;
- class;
- ]order;
- family;
- gender;
- species.
This means that the kingdom is the most comprehensive classification, which is specified with each classification until it reaches the species, which are the most specific. In the case of the human being, the species is Homo sapiens, and this is the only one still existing of the genus Homo, all others being extinct.
