The changes from extensive forests to more open habitats, which began 8 mya, are believed to be the main driver for the evolution of giraffes. [6] During this time, tropical plants disappeared and were replaced by arid C4 plants, and a dry savannah emerged across eastern and northern Africa and western India.
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).
The IUCN currently recognizes only one species of giraffe, with nine subspecies, one of which is the Nubian giraffe. [1] The Nubian giraffe, along with the whole species, were first known by the binomen Cervus camelopardalis described by Swedish zoologist Carl Linnaeus in the Systema Naturæ per regna tria naturæ, secundum classes, ordines, genera, species, cum characteribus, differentiis ...

Reticulated giraffes are a subspecies of giraffes. In fact, Kipekee is the first giraffe of her kind without spots since one that was born in Tokyo in 1972, according to David Bright.
Giraffomorpha is a clade of pecoran ruminants containing the superfamilies Palaeomerycoidea (Palaeomerycidae) and Giraffoidea (Giraffidae, Prolibytheriidae and Climacoceratidae), of which the giraffe and okapi of the Giraffidae are the only extant members of the once-diverse clade as a result of a decline in diversity after the Miocene as a result of declines in temperatures.
Giraffe tongues can be 20 inches long. Shrimp’s hearts are located in their heads. Interesting facts. The Burj Khalifa in Dubai is the world’s tallest building.
