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 name "giraffe" has its earliest known origins in the Arabic word zirāfah (زِرَافَةْ), of an ultimately unclear Sub-Saharan African language origin. [2] The Middle English and early Modern English spellings, jarraf and ziraph, derive from the Arabic form-based Spanish and Portuguese girafa. [3]
The northern giraffe (Giraffa camelopardalis), also known as three-horned giraffe, [2] is the type species of giraffe, G. camelopardalis, and is native to North Africa, although alternative taxonomic hypotheses have proposed the northern giraffe as a separate species. [3] [1]
A Penn State researcher has been trying to get to the bottom of the age-old question of why giraffes have long necks. Focus on research: Female giraffes drove the evolution of long necks, new ...
This small hornless ancestor resembled a tapir or small horse more than a rhino. Three families, sometimes grouped together as the superfamily Rhinocerotoidea, evolved in the late Eocene: Hyracodontidae , Amynodontidae and Rhinocerotidae , thus creating an explosion of diversity unmatched for a while until environmental changes drastically ...

Our very ancient animal ancestors had tails. “We found a single mutation in a very important gene,” said Bo Xia, a geneticist at the Broad Institute and co-author of a study published ...
Living giraffes were originally classified as one species by Carl Linnaeus in 1758, under the binomial name Cervus camelopardalis. Morten Thrane Brünnich classified the genus Giraffa in 1772. [ 6 ] Once considered a subspecies of the conglomerate Giraffa camelopardalis species, recent studies proposed the southern giraffe as a separate species ...
