Common chimpanzee - Wikipedia. The common chimpanzee (Pan troglodytes), also known as the robust chimpanzee, is a species of great ape. ![]() The 17 Day Diet (2011) by Mike Moreno: Food list Colloquially, the common chimpanzee is often called the chimpanzee (or . Evidence from fossils and DNA sequencing shows both species of chimpanzees are the sister group to the modern human lineage. The common chimpanzee is covered in coarse 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 4. Its gestation period is eight months. The infant is weaned at about three years old, but usually maintains a close relationship with its mother for several more years; it reaches puberty at the age of eight to 1. The common chimpanzee lives in groups which range in size from 1. 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 using 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. The common chimpanzee is listed on the IUCN Red List as an endangered species. Between 1. 70,0. 00 and 3. West and Central Africa.
The biggest threats to the common chimpanzee are habitat loss, poaching, and disease. The common chimpanzee was named Simia troglodytes by Johann Friedrich Blumenbach in 1. Figure 1 Relationships between Changes in Food and Beverage Consumption and Weight Changes Every 4 Years, According to Study Cohort. Study participants included. Learn the three major reasons why you should feed your pet a healthy, homemade diet, which comes at a fraction of the cost of high end commercial pet food. 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.Lorenz Oken moved it to the new genus Pan in 1. The species name troglodytes is a reference to the Troglodytae (literally . Blumenbach first used it in his De generis humani varietate nativa liber (. It is derived from a Tshiluba language term kivili- chimpenze, with a meaning of . Existing chimpanzee populations in West and Central Africa do not overlap with the major human fossil sites in East Africa. However, chimpanzee fossils have now been reported from Kenya. This would indicate that both humans and members of the Pan clade were present in the East African Rift Valley during the Middle Pleistocene. Taxonomy. Because no species other than Homo sapiens has survived from the human line of that branching, both chimpanzee species are the closest living relatives of humans. The lineage of humans and chimpanzees diverged from that of the gorilla about seven million years ago. A 2. 00. 3 study argues the common chimpanzee should be included in the human branch as Homo troglodytes, and notes experts say many scientists are likely to resist the reclassification, especially in the emotionally- charged and often disputed field of anthropology. Their bodies are covered by coarse, black hair, except for the face, fingers, toes, palms of the hands, and soles of the feet. Both its thumbs and big toes are opposable, allowing a precise grip. The common chimpanzee is both arboreal and terrestrial, and spends its nights in the trees, while most daylight hours are spent on the ground. The common chimpanzee is a 'knuckle walker', like the gorilla and the bonobo. It lives in a variety of habitats, including dry savanna, evergreen rainforest, montane forest, swamp forest and dry woodland- savanna mosaic. It prefers fruit above all other food items and even seeks out and eats them when they are not abundant. It also eats leaves and leaf buds. Seeds, blossoms, stems, pith, bark and resin. Insects and meat make up a small proportion of their diet, estimated as 2%. Other mammalian prey include red- tailed monkeys, yellow baboons, blue duikers, bushbucks, and common warthogs. This also varies from troop to troop and year to year. However, in all cases, the majority of their diet consists of fruits, leaves, roots, and other plant matter. Chimpanzees have complex social relationships and spend a large amount of time grooming each other. Males remain in their natal communities, while females generally emigrate at adolescence. As such, males in a community are more likely to be related to one another than females are to each other. Among males is generally a dominance hierarchy, and males are dominant over females. This is mainly due to chimpanzees having a high level of individual autonomy within their fission- fusion social groups. Also, communities have large ranges that overlap with those of other groups. As stated, these smaller groups also emerge in a variety of types, for a variety of purposes. For example, an all- male troop may be organized to hunt for meat, while a group consisting of lactating females serves to act as a . Due to the varying frequency at which chimpanzees associate, the structure of their societies is highly complicated. Male chimpanzees exist in a linear dominance hierarchy. Top- ranking males tend to be aggressive even during dominance stability. With this, a dominant male is unsure if any . Thus, a large amount of aggression occurs 5. Coalitions can also give an individual male the confidence to challenge a dominant male. The more allies a male has, the better his chance of becoming dominant. However, most changes in hierarchical rank are caused by dyadic interactions. Low- ranking males benefit from an unstable hierarchy and have increased sexual opportunities. Social hierarchies among adult females tend to be weaker. Nevertheless, the status of an adult female may be important for her offspring. A study published in 2. Patrol parties from large groups even take over a smaller group's territory, gaining access to more resources, food, and females. Oestrous females exhibit sexual swellings. Chimps tends to be promiscuous, and during estrus females mate with several males in her community. However, other forms of mating also exist. A community's dominant males sometimes restrict reproductive access to females. A male and female can form consortship and mate outside their community. In addition, females sometimes leave their communities and mate with males from neighbouring communities. Male chimps practice infanticide on unrelated young to shorten the interbirth intervals in the females. Also, accounts of infanticide by females have been reported; cases of female infanticide may be related to the dominance hierarchy in females or simply isolated pathological behaviours. The survival and emotional health of the young is dependent on maternal care. Newborn chimps are helpless; their grasping reflex is not strong enough to support them for more than a few seconds. Infants are unable to support their own weight for their first two months and need their mothers' support. They remain in continual contact for the rest of their first year. When they reach two years of age, they are able to move and sit independently. By four to six years, chimps are weaned and infancy ends. Juveniles remain close to their mothers, but they also have more interactions with other members of their community. Adolescent females move between groups and are supported by their mothers in agonistic encounters. Adolescent males spend time with adult males in social activities like hunting and boundary patrolling. Other facial expressions include the . When in an aggressive mode, a chimp swaggers bipedally, hunched over and arms waving, in an attempt to exaggerate its size. The most common and important call in adults is the . These calls are made when individuals are excited. They modify sticks, rocks, grass, and leaves and use them when foraging for honey, termites, ants, nuts, and water. Despite the lack of complexity, forethought and skill are seen in making these tools and should be considered such. For hives of the dangerous African honeybees, chimps use longer and thinner sticks to extract the honey. West African chimps crack open hard nuts with stones or branches. Nut cracking is also difficult and must be learned. Chimps may also hunt as a coordinated team, so that they can corner their prey even in a continuous canopy. In Gombe, the chimpanzee also fears adult female colobus monkeys, and prefers to snatch infants from their mother's bellies without harming the mothers. When caught and killed, the meal is distributed to all hunting party members and even bystanders. They were even thought to have kidnapped and raped women. The Gio people of Liberia and the Hemba people of the Congo have created blocky and crude masks of the animals. The mask may have a smile which suggests drunken anger, insanity or horror. They wear these masks when teaching young people how not to act; performing rituals where they act wildly and uncivilized. They may also act out these rituals during funerals, representing the . Accordingly, entertainment acts featuring chimpanzees dressed up as humans have been traditional staples of circuses and stage shows. Other long- term study sites begun in 1. A. Kortlandt in the eastern Democratic Republic of the Congo and Junichiro Itani in Mahale Mountains National Park in Tanzania. The numbers in this diagram are branch lengths, a measure of evolutionary distinctness. Based on protein electrophoresis data of Goldman et al. After the completion of the Human Genome Project, a Chimpanzee Genome Project was initiated. In December 2. 00. P2transcription factor which is involved in speech development, have undergone rapid evolution in the human lineage. A draft version of the chimpanzee genome was published on September 1, 2. Chimpanzee Sequencing and Analysis Consortium. Typical human and chimp protein homologs differ in only an average of two amino acids. About 3. 0% of all human proteins are identical in sequence to the corresponding chimp protein. Duplications of small parts of chromosomes have been the major source of differences between human and chimp genetic material; about 2. Results from human and chimp genome analyses, currently being conducted by geneticists including David Reich, should help in understanding the genetic basis of some human diseases.

It goes by many names, but the fat that lies under your belly and surrounds your intestines is also referred to as omental or visceral fat by health professionals. While nobody enjoys carrying around excess fat, this type of fat is especially harmful because it may increase your risk of heart disease, dementia, asthma and certain types of cancer, including breast and colon. No one diet can help you lose omental fat specifically, but a healthy, reduced- calorie diet that promotes overall weight loss can certainly help decrease abdominal fat. To lose weight, and help lose some of your omental fat, you need to eat fewer calories than you burn. In general, most women can lose weight by limiting intake to 1,0. National Heart, Lung and Blood Institute. If you're losing weight too quickly - - such as more than 2 pounds a week - - increase your daily calorie intake by 1. Losing weight too quickly can lead to a slower metabolism and cause your body to store fat more efficiently later on down the line, according to the Harvard Medical School. When trying to lose weight, eating a balanced diet that includes a variety of foods from all the food groups - - including fruits, vegetables, grains, proteins and dairy - - is the way to go. Your meal plan to help you lose omental fat should include three meals of about the same size, plus one snack each day. Eating regularly helps keep energy levels up and hunger away. Try to include as many food groups as possible at each meal to up your nutrient intake. Including certain types of foods and nutrients on your diet to reduce omental fat may make it easier for you to lose the unwanted fat. Replacing refined carbs - - white bread and soda - - with complex carbs - - whole grains, fruits and vegetables - - can make it easier for you to lose weight. Eating more polyunsaturated fats - - salmon, tuna, nuts, seeds and soy oil - - instead of saturated and trans fats may also help prevent your belly from growing larger. Upping your intake of calcium- rich foods - - milk, yogurt and tofu - - may also help whittle your waist. For breakfast on your diet to reduce omental fat, you might enjoy oatmeal topped with fresh berries and walnuts with a cup of nonfat milk. A healthy lunch might include a bowl of lentil soup, mixed greens tossed with diced chicken, balsamic vinegar and soy oil, a fresh orange and a container of nonfat yogurt. A satisfying dinner meal might include broiled salmon with a baked sweet potato and steamed broccoli. For snack, a bowl of unsweetened whole- grain cereal with nonfat milk makes a good choice.
