What is the largest classification category?
1 Answer. Domain is the largest group in that it breaks all living things into three broad categories. Species is the smallest group in the classification system.
Is kingdom the largest classification?
Charles Linnaeus, a Swedish botanist, developed a hierarchical system of classification including seven levels called taxa. The Kingdom is the largest and most inclusive of the taxonomic categories. Species is the smallest and least inclusive of the taxonomic categories.
Which category is larger than a kingdom?
As scientists began to understand more about DNA, evolutionary biologists established a new taxonomic category—the domain. A domain is a larger and more inclusive category than a kingdom. There are three domains—Bacteria, Archaea, and Eukarya.
What are the 3 main domains of life?
According to this system, the tree of life consists of three domains: Archaea, Bacteria, and Eukarya. The first two are all prokaryotic microorganisms, or mostly single-celled organisms whose cells have no nucleus.
Which is the most advanced of the six kingdoms of life?
Archaebacteria are the most recent addition to the kingdoms of organisms.
What is the smallest category?
Species is the smallest and least inclusive of the taxonomic categories. Kingdom, Phylum, Class, Order, Family, Genus, Species.
What is a category classification?
Categorization is the human ability and activity of recognizing shared features or similarities between the elements of the experience of the world (such as objects, events, or ideas), organizing and classifying experience by associating them to a more abstract group (that is, a category, class, or type), on the basis …

Answer. Humans, chimpanzees, gorillas, orangutans and their extinct ancestors form a family of organisms known as the Hominidae. Researchers generally agree that among the living animals in this group, humans are most closely related to chimpanzees, judging from comparisons of anatomy and genetics.
Which two organisms are most closely related?
Brown algae and dinoflagellates. Explanation: In a phylogenetic tree, two species are considered as most closely related if they share a more common ancestor than the others. The nodes of tree represent the common ancestor, while the tips of branches represent species originated from that ancestor.
