The lunar cycle can also influence the cheetah's routine—activity might increase on moonlit nights as prey can be sighted easily, though this comes with the danger of encountering larger predators. [ 58 ] [ 114 ] Hunting is the major activity throughout the day, with peaks during dawn and dusk. [ 63 ]
The first stage of the insect life cycle is the egg, or embryo, for all developmental strategies. The egg begins as a single cell which divides and develops into the larval form before hatching. Some insects reproduce by parthenogenesis or may be haplodiploid, and produce viable eggs without fertilization. The egg stage in most insects is very ...
In July 2020, marine biologists reported that aerobic microorganisms (mainly), in "quasi-suspended animation", were found in organically poor sediments, up to 101.5 million years old, 68.9 metres (226 feet) below the seafloor in the South Pacific Gyre (SPG) ("the deadest spot in the ocean"), and could be the longest-living life forms ever found ...
The cheetah population is declining in large part because of human influences like climate change and habitat destructions. But some research has suggested that cheetahs are contributing to their ...
In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of stages of the life of an organism, that begins as a zygote, often in an egg, and concludes as an adult that reproduces, producing an offspring in the form of a new zygote which then itself goes through the same series of stages, the ...
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 ...
