Common Chimpanzee - Pan troglodytes
The common chimpanzee (Pan troglodytes), also known as the robust chimpanzee, is a species of great ape. Colloquially, the common chimpanzee is often called the chimpanzee (or 'chimp'), though technically this term refers to both species in the genus Pan: the common chimpanzee and the closely related bonobo, formerly called the pygmy chimpanzee. Evidence from fossils and DNA sequencing show that both species of chimpanzees are the sister group to the modern human lineage. The common chimpanzee is covered in course black hair but has a bare face, fingers, toes, palms of the hands and soles of the feet. It is considered more robust than the bonobo, weighing between 40 and 65 kg (88 and 140 lb) and measuring approximately 1.6 to 1.3 m (5 ft 3 in to 4 ft 3 in) from head to tail. Its gestation period is eight months. Infants are weaned when they are about three years old, but usually maintain a close relationship with their mother for several more years; it reaches puberty at the age of eight to ten, and its lifespan in captivity is about fifty years. The common chimpanzee lives in groups which range in size from 15 to 150 members, although individuals travel and forage in much smaller groups during the day. The species lives in a male-dominated, strict hierarchy, which means disputes can generally be settled without the need for violence. Nearly all chimpanzee populations have been recorded using tools, modifying sticks, rocks, grass, and leaves and use them for acquiring honey, termites, ants, nuts, and water. The species has also been found creating sharpened sticks to spear Senegal bushbabies out of small holes in trees.
Neanderthal - Homo neanderthalensis
Neanderthals were members of a now-extinct species, or species sub-group, closely related to modern humans that is known from Pleistocene specimens found in Europe and parts of western and central Asia. Like modern humans they are classified as part of the genus Homo. The term "Neanderthal", a shortening of "Neanderthal man", is sometimes spelled Neandertal, the modern spelling of the location in Germany where the species was first discovered. Neanderthals are classified alternatively as a subspecies of Homo sapiens (Homo sapiens neanderthalensis) or as a separate human species (Homo neanderthalensis). Genetic evidence suggests they are closer to non-African than African anatomically modern humans, which is probably due to interbreeding between Neanderthals and the ancestors of the Eurasians. This is thought to have occurred between 80,000 and 50,000 years ago, shortly after (or perhaps before) the proto-Eurasians emigrated from Africa, and while they were still one population. It resulted in 1–4% of the genome of people from Eurasia having been contributed by Neanderthals. were much stronger than modern humans, having particularly strong arms and hands. Males stood 164–168 cm (65–66 in) and females about 152–156 cm (60–61 in) tall as well with males weighing 80 kg (176 lbs) and females weighing 54 (119 lbs).
