DENDROLOGY

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: -Scientists use a two-name system called a Binomial Naming System. Scientists name animals and plants using the system that describes the genus and species of the organism. The first word is the genus and the second is the species.

Detailed explanation-3: -Taxonomy is the study of relationships between living things and the formal classification of organisms into groups based upon those hypothesized relationships. Organisms are classified based upon their similarities and differences. Think about your own biological relatives.

Detailed explanation-4: -Every living creature has DNA, which has a lot of inherited information about how the body builds itself. Scientists can compare the DNA of two organisms; the more similar the DNA, the more closely related the organisms. This method can also help when looks are deceptive.
