What are the basic hierarchical classification groups for living things?

The hierarchical system of classification places organisms in various taxa. All taxa are divided into smaller and larger groups. Hierarchically the existing system includes Kingdom; Phylum, Class; Order; Family; Genus; and Species.

What is the binomial system used in the nomenclature of organisms?

The binomial system of naming species involves two names in Latin called scientific names. The scientific name of organisms is derived from their genus and species level. eg. Genus: Homo Species: Sapiens is called Homo Sapiens.

Why do classification systems constantly change?

Millions of plants, animals, and microorganisms remain undiscovered or unclassified. Discovering new species and new data on existing species is a major factor in reclassification. Some discovered organisms do not fit in existing systems and require change. Therefore new classification systems have to be devised now and then to accommodate all of them.

What are the benefits of recent advancements in taxonomy?

The emergence of molecular phylogenetic tools enables us to compare the DNA of different organisms. This has resulted in classification at the genetic and proteomic levels. This helps in directly comparing evolutionary relevance (phylogeny).

How living organisms are classified?

Living things are divided into five kingdoms: animal, plant, fungi, protist and monera.
