Cheetahs in the Sahara and Maasai Mara in Kenya hunt after sunset to escape the high temperatures of the day. [129] Cheetahs use their vision to hunt instead of their sense of smell; they keep a lookout for prey from resting sites or low branches. The cheetah will stalk its prey, trying to conceal itself in cover, and approach as close as ...
Two camera trapping surveys in the Ahaggar massif revealed that cheetahs in this area exhibit several behavioral adaptations to this harsh climate: they are predominantly nocturnal and active between sunset and early mornings; they travel larger distances and occur at a lower density than cheetahs living in savannas.

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]
Cheetahs might be fast, but they aren't the smartest of felines around. The cheetah population is declining in large part because of human influences like climate change and habitat destructions.
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.

Miracinonyx (colloquially known as the "American cheetah") is an extinct genus of felids belonging to the subfamily Felinae that was endemic to North America from the Pleistocene epoch (about 2.5 million to 16,000 years ago) and morphologically similar to the modern cheetah (Acinonyx jubatus), although its apparent similar ecological niches have been considered questionable due to anatomical ...
In contrast, maladaptive behavior is a type of behavior that is often used to reduce one's anxiety, but the result is dysfunctional and non-productive coping. For example, avoiding situations because you have unrealistic fears may initially reduce your anxiety, but it is non-productive in alleviating the actual problem in the long term.
In evolutionary biology, an evolutionary arms race is an ongoing struggle between competing sets of co-evolving genes, phenotypic and behavioral traits that develop escalating adaptations and counter-adaptations against each other, resembling the geopolitical concept of an arms race. These are often described as examples of positive feedback. [1]
