I LOVE DOG by Scrum Zoo

Scientific Name of Dogs:

 

The evolution of the gray wolf occurred over a geologic time scale of 800,000 years, transforming the first Middle Pleistocene wolf specimen that is recognized as being morphologically similar to Canis lupus into today's dog, dingo and gray wolf. Ecological factors including habitat type, climate, prey specialization and predatory competition will greatly influence the wolf's genetic population structure and cranio-dentalplasticity. Wolves went through a population bottleneck 20,000 years before present (YBP), which indicates that many wolf populations had gone extinct at a time that coincided with the Last Glacial Maximum and the expansion of modern humans worldwide with their technology for capturing large game. The domestic dog is the most widely abundant large carnivore and a descendant from one of those now-extinct wolf populations. Today, the wolf is represented by the many extant subspecies of Canis lupus, which includes the dog and dingo.

 

1. Primary Species: Canis lupus familiaris

The domestic dog is a domesticated canid which has been selectively bred over millennia for various behaviours, sensory capabilities, and physical attributes.

 

1. Sub Species

 

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

Domain Eukarya

-Organisms have cells with a true nucleus and membrane-bound organelles.

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. Domestic dogs are ancestors of the grey wolf.
