Describe the modern system of classification. The modern system classifies organisms into eight levels: domain, kingdom, phylum, class, order, family, genus, and species. The scientific name given to an organism is based on binomial nomenclature. Artificial system of classification which is mainly based on the morphological characters, non-evolutionary features e. Linnaeus attempted a natural classification but did not get far.
His concept of a natural classification was Aristotelian; i. An artificial system of classification is based upon one or a few easily observable characteristics,and is devised and used for a limited purpose where convenience and speed are important. A natural system of classification is based on a large number of characters. The main difference between Natural Classification and Artificial Classification is that Natural Classification is based on the important points of similarities, whereas Artificial Classification is according to the some less important or unimportant points of likeness.

The six basic animal groups include amphibians, birds, fish, invertebrates, mammals, and reptiles. Animals are then broken down into two types: vertebrates and invertebrates. Animals with a backbone are vertebrates. Three different types of animals exist: herbivores, omnivores, and carnivores.
Herbivores are animals that eat only plants. Carnivores are animals that eat only meat. Omnivores are animals that eat both plants and meat. Omnivores are a diverse group of animals. Examples of omnivores include bears, birds, dogs, raccoons, foxes, certain insects, and even humans. Animals that hunt other animals are known as predators, while those that are hunted are known as prey.
Since omnivores hunt and are hunted, they can be both predators and prey…. Humans are carnivores. A carnivore is an organism mostly animals that derives its food and energy requirements exclusively or nearly so from the tissue and meat of other animals….
The science of classifying living things is called taxonomy. Linnaeus introduced the classification system that forms the basis of modern classification. Taxa in the Linnaean system include the kingdom, phylum, class, order, family, genus, and species. The Greek scientist, Aristotle B. Aristotle developed the first classification system, which divided all known organisms into two groups:. For example, frogs are born in water and have gills like fish, but when they grow up they have lungs and can live on land.
So how would Aristotle classify frogs? But the penguin is a bird that cannot fly. So Aristotle would not have classified them as birds. Linnaeus, like Aristotle, classified organisms according to their traits. The classification systems of both Aristotle and Linnaeus started with the same two groups: Plants and Animals. Linnaeus called these groups, kingdoms. But, unlike Aristotle, Linnaeus divided kingdom into five levels: class, order, genus, species, and variety.
