Question

What are the seven ranks in the Linnaean classification system, beginning with the smallest?

Answer 1

Hint: To understand the diversity and evolutionary history of life on earth, classification is the most important step. Many scientists have given their classification based on their own concepts and ideas but the most acceptable one was proposed by Carolus Linnaeus.

Complete answer:
Carolus Linnaeus was a Swedish botanist who developed his classification in 1700 was known as the Linnaean classification system. He classified all the living things known at that time into seven groups on the basis of physical traits, such as the number of legs or shape of leaves. The Linnaean classification system consists of a hierarchy of groupings, called taxa. This texa ranges from the species to the kingdom beginning with the smallest.
Species: These are the smallest and the most exclusive grouping. These include organisms that can produce fertile offspring together.
-Genus: In a genus, closely related species are grouped together.
-Family: After order, the organisms are classified into a family. Within the order of primates, families include Hominidae that includes great apes and humans, Cercopithecidae which includes old-world monkeys such as baboons, and hylobatidae that includes gibbons and lesser apes.
-Order: These are subdivisions of class. Within the class Mammalia, let's take the examples of an order cetacea. The order cetacea is including whales and dolphins, Carnivora is including carnivores, primates is including monkeys, apes, and humans, and also Chiroptera including bats.
-Class: The classes are the subdivision of the phylum. The classes included in the phylum Chordata are Mammalia includes mammals, reptilia includes different reptiles and Osteichthyes includes different fish, among others.
-Phylum: It is just below the kingdom in the hierarchy of Linnaean classification. The major phyla include Chordata having animals with a backbone, Arthropoda includes insects, and Molluscs such as snails within the animal kingdom.
-Kingdom: It is the largest and the most inclusive grouping. It includes the organisms that share just a few basic similarities. For example plants and animals.

Note:
-Carolus Linnaeus is known as the “father of taxonomy” for his contribution.
-All modern classification systems have their roots within the Linnaean classification system.
-The Linnaean system is predicated on similarities in obvious physical traits. It contains the hierarchy of taxa, from the kingdom to the species.
-Each species is given a singular two-word Latin name.
