The female's home range's size can depend on the prey base. Cheetahs in southern African woodlands have ranges as small as 34 km 2 (13 sq mi), while in some parts of Namibia, they can reach 1,500 km 2 (580 sq mi). Female cheetahs can reproduce at 13 to 16 months of age and with a typical age of sexual maturity between 20 and 23 months. [40]
However, it is the darkest in fur color. This cheetah has the most widespread and separated black dorsal spots, but smaller than that of the East African cheetah's. [9] [10] In contrast to the East African cheetah, the Northeast African cheetah has no spots on the hind feet, although some among the Chadian population have spotted hind legs. [4]
Cheetahs can go from 0 to 97 km/h (0 to 60 mph) in less than 3 seconds. [106] There are indirect ways to measure how fast a cheetah can run. One case is known of a cheetah that overtook a young male pronghorn. Cheetahs can overtake a running antelope with a 140 m (150 yd) head start.
The earliest African cheetah fossils from the early Pleistocene have been found in the lower beds of the Olduvai Gorge site in northern Tanzania. [7]Not much was known about the East African cheetah's evolutionary story, although at first, the East and Southern African cheetahs were thought to be identical as the genetic distance between the two subspecies is low. [13]
In Mali, cheetahs were sighted in Adrar des Ifoghas and in the Kidal Region in the 1990s. [7] In 2010, a cheetah was photographed in Niger's Termit Massif by a camera trap. [8] No cheetah was recorded in the North Province, Cameroon during a survey carried out between January 2008 and May 2010. [9]
Adaptationism is an approach to studying the evolution of form and function. It attempts to frame the existence and persistence of traits, assuming that each of them arose independently and improved the reproductive success of the organism's ancestors.
In behavioral ecology, adaptive behavior is any behavior that contributes directly or indirectly to an individual's reproductive success, and is thus subject to the forces of natural selection. [1] Examples include favoring kin in altruistic behaviors , sexual selection of the most fit mate, and defending a territory or harem from rivals.
This adaptation means irreversible, long-term physiological responses to high-altitude environments associated with heritable behavioral and genetic changes. While the rest of the human population would suffer serious health consequences at high altitudes, the indigenous inhabitants of these regions thrive in the highest parts of the world.
