GIRAFFE PALAEONTOLOGY AND EVOLUTIONARY BIOCHEMISTRY Palaeontological research directed towards the understanding of the evolution of giraffes began several years before Darwin & Wallace (1858) announced their discoveries. It seems to have been initiated as early as 1838 by Cautley. He found an elon- 2021-04-20 · NATURAL HISTORY. GIRAFFE} Giraffa camelopardalis Family: Giraffidae. Description: The tallest land mammal, with a neck as long as 6 feet, the giraffe is also well known for the unique brown and white pattern on its coat (“pelage”) and its lengthy eyelashes and legs.

The sequences, published on 17 May in Nature Communications 1, reveal clues to the age But in fact they result from history: the fact that at any given point natural selection has no choice but to work from what is already available. More than most animals, giraffes reflect the fact that organisms have not been created from scratch (or if they were, the Special Creator was notably inept). They’re closely related to the okapi, and more loosely to the pronghorn. Other than that, nothing is closely related to them, although they are distantly related to other cloven-hoofed ungulates such as sheep, goats, deer, antelope, cattle etc.

The origins of Giraffidae are hazy. DNA analysis Their affiliation with living giraffes was quickly realized, and their evolutionary significance became apparent.

Habitat: Giraffes use both semi-arid savannah and savannah woodlands in Africa. Giraffe "horns" are different from most animal horns. They are just bony bumps covered with skin and hair, and are called ossicones.
