Everything about Class Biology totally explained
A
class is the
taxonomic rank in the
biological classification of organisms in
biology below
phylum and above
order.
For example,
Mammalia is the class used in the classification of
dogs, whose phylum is
Chordata (animals with
notochords) and order is
Carnivora (mammals that eat meat).
History of the concept
The class as a distinct of biological classification having its own distinctive name (and not just called a
higher genus (genus summum)) was first introduced by a
French botanist Joseph Pitton de Tournefort in his classification of plants (appeared in his 1694
Eléments de botanique).
Carolus Linnaeus was the first to apply it consistently to the division of all three
kingdoms of Nature (
minerals,
plants, and
animals) in his
Systema Naturae (
1735, 1st. Ed.). Since then class had been considered the highest level of the taxonomic hierarchy until the
embranchements, now called
phyla, and
divisions were introduced in the nineteenth century.
