The chimpanzee (/ tʃ ɪ m p æ n ˈ z i /; Pan troglodytes), also simply known as the chimp, is a species of great ape native to the forests and savannahs of tropical Africa.It has four confirmed subspecies and a fifth proposed one.
The International Commission on Zoological Nomenclature adopted Pan as the only official name of the genus in 1895, [9] though the "cave-dweller" connection was able to be included, albeit at the species level (Pan troglodytes – the common chimpanzee) for one of the two species of Pan.
The trophic level of an organism is the number of steps it is from the start of the chain. A food web starts at trophic level 1 with primary producers such as plants, can move to herbivores at level 2, carnivores at level 3 or higher, and typically finish with apex predators at level 4 or 5. The path along the chain can form either a one-way ...
Top-down control, therefore, refers to situations where the abundance, diversity or biomass of lower trophic levels depends on effects from consumers at higher trophic levels. [10] A trophic cascade is a type of top-down interaction that describes the indirect effects of predators. In a trophic cascade, predators induce effects that cascade ...
A pyramid of biomass shows the relationship between biomass and trophic level by quantifying the biomass present at each trophic level of an ecological community at a particular time. It is a graphical representation of biomass (total amount of living or organic matter in an ecosystem) present in unit area in different trophic levels.
Humans and chimpanzees are 99.1% identical at the codingl level, with 99.4% similarity at the nonsynonymous level and 98.4% at the synonymous level. [15] The alignable sequences within genomes of humans and chimpanzees differ by about 35 million single-nucleotide substitutions.
The aquatic ape hypothesis (AAH), also referred to as aquatic ape theory (AAT) or the waterside hypothesis of human evolution, postulates that the ancestors of modern humans took a divergent evolutionary pathway from the other great apes by becoming adapted to a more aquatic habitat. [1]
The western chimpanzee or West African chimpanzee [1] (Pan troglodytes verus) is a Critically Endangered subspecies of the common chimpanzee. It inhabits western Africa, specifically Côte d'Ivoire , Guinea , Liberia , Mali , Senegal , Ghana , Guinea-Bissau , but has been extirpated in three countries: Benin , Burkina Faso , and Togo .
