They can keep a lookout for predators, but there is another reason they may have such long necks. Some scientists think giraffes evolved such long necks to fight other giraffes.
Thus, these nerve cells have a length of nearly 5 m (16 ft) in the largest giraffes. [78] Despite its long neck and large skull, the brain of the giraffe is typical for an ungulate. [80] Evaporative heat loss in the nasal passages keep the giraffe's brain cool. [54] The shape of the skeleton gives the giraffe a small lung volume relative to its ...
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 ...
The giraffe weevil (Trachelophorus giraffa) is a species of small weevil endemic to Madagascar. [2] They are black-bodied and have bright red elytra covering their wings. . Giraffe weevils are known for their elongated necks, with the males having necks 2 to 3 times the size of their female counte
The okapi's neck is long compared to most ruminants, but not nearly so long as the giraffe's. Male giraffes are the tallest of all mammals: their horns reach 5.5 m (18 ft) above the ground and their shoulder 3.3 m (11 ft), whereas the okapi has a shoulder height of 1.7 m (5 ft 7 in). [9]
The sauropods and giraffes independently evolved long necks. [74] The horned snouts of ceratopsian dinosaurs like Triceratops have also evolved several times in Cenozoic mammals: rhinos, brontotheres, Arsinoitherium, and Uintatherium. [75] Rhynchosaur teeth resemble that of the extant rodents.

It is characterised by its long, slender neck and limbs, the flat, wedge-like head and the large, round eyes. Males are nearly 89–105 cm (35– 41 + 1 ⁄ 2 in) tall, and the shorter females 80–100 cm (31–39 in); the head-and-body length is typically between 140 and 160 cm (55 and 63 in). Males weigh between 31 and 52 kg (68 and 115 lb ...
