The coat patterns of modern giraffes may also have coincided with these habitat changes. Asian giraffes are hypothesised to have had more okapi-like colourations. [6] The giraffe genome is around 2.9 billion base pairs in length, compared to the 3.3 billion base pairs of the okapi. Of the proteins in giraffe and okapi genes, 19.4% are identical.
Additionally, their feet do not have the small claws and digits of rodents or lagomorphs, instead resembling miniature elephant-feet, with toenails specially adapted for climbing rocks. The hare, for chewing the cud without having cloven hooves. [2] [5] The pig, for having cloven hooves without chewing the cud. [6] [7]
The hoof (pl.: hooves) is the tip of a toe of an ungulate mammal, which is covered and strengthened with a thick and horny keratin covering. [1] Artiodactyls are even-toed ungulates, species whose feet have an even number of digits; the ruminants with two digits are the most numerous, e.g. giraffe, deer, bison, cattle, goat, pigs, and sheep.

Cloven hooves of roe deer (Capreolus capreolus), with dewclaws. The hoof is the tip of the toe of an ungulate mammal, strengthened by a thick horny covering. The hoof consists of a hard or rubbery sole, and a hard wall formed by a thick nail rolled around the tip of the toe. Both the sole and the edge of the hoof wall normally bear the weight ...
Giraffes, just like humans, have seven cervical vertebrae. Unlike humans, giraffe cervical vertebrae are attached to each other with ball and socket joints, making them able to bend their necks in ...
The Giraffidae are a family of ruminant artiodactyl mammals that share a recent common ancestor with deer and bovids.This family, once a diverse group spread throughout Eurasia and Africa, presently comprises only two extant genera, the giraffe (between one and eight, usually four, species of Giraffa, depending on taxonomic interpretation) and the okapi (the only known species of Okapia).
Suina (including pigs) have been around since the Eocene. In the late Eocene or the Oligocene, two families stayed in Eurasia and Africa; the peccaries, which became extinct in the Old World, exist today only in the Americas. [citation needed] Sivatherium was a relative of giraffes with deer-like forehead ossicones.
Giraffes actually fight using this same technique to establish dominance during mating season. Raw Tribe explains more about this neck-to-neck combat, "Giraffe fights involve a unique behavior ...
