NEET BIOLOGY

Detailed explanation-1: -In the eighteenth century, a scientist named Carl Linnaeus first proposed organizing the known species of organisms into a hierarchical taxonomy. In this system, species that are most similar to each other are put together within a grouping known as a genus.

Detailed explanation-2: -There are seven obligate categories in taxonomic hierarchy: Kingdom, Phylum or Division, Class, Order, Family, Genus and Species. As we go from Kingdom towards Species, the number of similar characters increases. For example, organisms in a genus will have more common characters than all the organsims in a Kingdom.

Detailed explanation-3: -Genus. The genus (plural, genera) is the taxonomic rank between family and species. The groups of organisms in a genus share many structural similarities and are very closely related. Members of a genus are more closely related to each other than they are to other genera in the same family.

Detailed explanation-4: -Organisms of the same species will have similar genomes and a similar proteome, or makeup of proteins. Looking at these molecular signatures can help scientists determine if two organisms are the same species.
