How do we give a name to a new species?

We can represent the classification in a tree structure
For years the domestic dog was classified as a species, Canis familiaris. However, recent DNA analysis shows domestic dogs evolved from wolves, Canis lupus. This led scientists to reclassify the domestic dog as Canis lupus familiaris, a subspecies of the wolf rather than a separate species.

Kingdom Animalia
-Organisms are multicellular with no cell walls and are heterotrophs.
Phylum Chordata
-Organisms possess notochord, postanal tail and pharyngeal pouches at some point during their life cycle. Organisms have bilateral symmetry, segmented bodies, developed coelom, dorsal nerve cord, closed circulatory systems, complete digestive system and an endoskeleton.
Subphylum Vertebrata
-Organisms have a vertebral column or a backbone. They move due to muscles attached to their endoskeletons. These organisms also have a digestive system with large glands (pancreas and liver) and a ventral heart with 2-4 chambers.
Class Mammalia
-Organisms have 3 middle ear bones, hair, and produce milk from mammary glands.
Order Carnivora
-Organisms primarily eat meat. They have 4 to 5 toes on each leg or arm and have sharp canine teeth.
Family Canidae
-Organisms have elongated feet and legs, 5 toes on the forefeet and 4 toes on the hindfeet, non-retractile claws, and usually form packs with strict social hierarchy systems.
Genus Canis
-This includes wolves, coyotes, jackals and domestic dogs.
Subspecies Canis lupus familiaris
-Canis is the Latin word for dog.
