Camelops is an extinct genus of camel that lived in North and Central America from the middle Pliocene (from around 4-3.2 million years ago) to the end of the Pleistocene (around 13-12,000 years ago). It is more closely related to living camels than to lamines (llamas, alpacas, vicuñas, and guanacos), making it a true camel of the Camelini tribe.
Along with many other megafauna in North America, the original wild camels were wiped out during the spread of the first indigenous peoples of the Americas from Asia into North America, 10 to 12,000 years ago; although fossils have never been associated with definitive evidence of hunting. [73] [74] Most camels surviving today are domesticated.
The family diversified and prospered, with the two living tribes, the Camelini and Lamini, diverging in the late early Miocene, about 17 million years ago, but remained restricted to North America until about 6 million years ago, when Paracamelus crossed the Bering land bridge into Eurasia, giving rise to the modern camels, and about 3-2 ...
Camels got better at closing their noses to keep out sand and lock in moisture. They learned to drink saltwater, eat toxic plants and position their bodies in the coolest possible angles to the sun.
By the Oligocene, camels were the size of sheep and had only two toes. [144] Gradually over time horses also lost toes, but unlike camels, horses' were reduced to a single digit. [145] By the Oligocene their teeth had adapted to endure abrasion from silica in their increasingly grassy diets. [145] Horses gradually became common throughout the ...
The dromedary (Camelus dromedarius), also known as the dromedary camel, Arabian camel and one-humped camel, is a large camel of the genus Camelus with one hump on its back. It is the tallest of the three camel species; adult males stand 1.8–2.4 m (5 ft 11 in – 7 ft 10 in) at the shoulder, while females are 1.7–1.9 m (5 ft 7 in – 6 ft 3 in) tall.

Where Do Camels Belong? is a book by biologist Ken Thompson. [1] [2] [3] [4]The book examines the science and history of invasive species.The book describes itself as "an examination of the whole question of native and alien species, and what might be called an alien invasions industry—and its implications".
