By Carol Clark, Emory University It's been a puzzle why our two closest living primate relatives, chimpanzees and bonobos, have widely different social traits, despite belonging to the same genus. Now, a comparative analysis of their brains shows neuroanatomical differences that may be responsible for these behaviors, from the aggression more typical of chimpanzees to the social tolerance of bonobos. "What's remarkable is that the data appears to match what we know about the human brain and...

Experiment stresses consequences of placing newly discovered fossils on human family tree Someday a future intelligent organism could sweep away a million years of dust and find the bones of a Homo sapiens and wonder what he was. Further research would show Homo sapiens walked upright, lived in communities and buried their dead. But this future intelligent organism might be faced with an old puzzle--determining where Homo sapiens came from. "If their cognitive world induced them to ask the...

Long-term planning for chimpanzee rescue and care Every year throughout Africa, primate rescue centers are flooded with chimpanzee orphans, primarily victims of the bushmeat trade. When adults are killed for meat the surviving infants are often offered for sale as pets, and those that get confiscated by law enforcement are taken to sanctuaries for care. A new study, published in the International Journal of Primatology, examines 11 Pan African Sanctuary Alliance (PASA) member facilities,...

Chimpanzees, gorillas and other primate, including humans, share similar aging rates and mortality gender gap A new study says chimps, gorillas and other primates grow old gracefully much like humans. The findings come from the first-ever multi-species comparison of primate aging patterns reported in the March 11 issue of Science. It was long thought that humans, who have relatively long life spans, age more slowly than other animals. But new research funded by the National Science...

Humans share 98.7 percent of our DNA with chimpanzees, but we share one important similarity with one species of chimp, the common chimpanzee, that we don't share with the other, the bonobo. That similarity is violence. While humans and the common chimpanzee wage war and kill each other, bonobos do not. "There has never been a recorded case in captivity or in the wild of a bonobo killing another bonobo," notes anthropologist Brian Hare. Hare is an assistant professor in evolutionary...

Cheryl Knott's NSF-supported work helps us understand why orangutans require protection and conservation For the last 18 years, Cheryl Knott of Boston University has been racing the clock. While she researches orangutans in the rainforests of Gunung Palung National Park in Borneo, the numbers of this magnificent ape steadily plummet. The outlook for orangutans--one of human's closest relatives--is dire because there are only a few tens of thousands of them currently left in the wild, and they...

How smart are copy cats? Maybe it depends on your species You know the saying "monkey see, monkey do?" How about "orangutan see, orangutan do?" If that holds true, the small orangutan peering over his mother's shoulder in an enclosure at Zoo Atlanta should learn how to get a tasty treat just by watching how she gets one. "One of the questions that we were looking at is how individuals learn from one another," says Marietta Dindo, a primatologist studying orangutans and their behaviors. With...

Puzzled scientists are debating if the shrinking brains of humans is a sign we are growing dumber or that evolution is making the key motor leaner and more efficient. The average size of modern human brains has decreased about 10 percent during the last 30,000 years -- from 1,500 to 1,359 cubic centimeters, the size of a tennis ball, reports the AFP news agency. The brains of females, which are on average smaller than those of men, have also experienced an equivalent drop in size. These...

According to a recently published genome analysis of orangutans, the two populations of the creatures in the forests of Borneo and Sumatra have similarities and differences between the Great Ape family and their human cousins. "As more information about primates becomes known, we find additional genes for which there is positive selection," said Dr. Kim Worley, associate professor in the Baylor College of Medicine Human Genome Sequencing Center and an author of the report that appears in the...

Finding adds to growing evidence of a biological basis for gender-specific play in humans The must-have gift for young female chimpanzees this holiday season might be in the Christmas tree, not under it. That's the finding of scientists at Harvard University and Bates College, who say female chimpanzees appear to treat sticks as dolls, carrying them around until they have offspring of their own. Young males engage in such behavior much less frequently. The new work by Sonya M. Kahlenberg and...

Homo sapiens
2013-09-24 13:55:52

Homo sapiens is the scientific name for the human species. Homo is the human genus, which also includes Neanderthals and various other extinct species of hominid. H. sapiens is the only surviving species of the genus Homo. Modern humans are the subspecies Homo sapiens sapiens, distinguished from their direct ancestor, Homo sapiens idaltu (http://en.wikipedia.org/wiki/Homo_sapiens_idaltu). Subspecies of H. sapiens include Homo sapiens idaltu, roughly translated as “elder wise human” and...

The Siamang (Symphalangus syndactylus), is an arboreal gibbon native to the forests of Malaysia, Thailand, and Sumatra. Its range overlaps with the Lar Gibbon and Agile Gibbon. While the illegal pet trade takes a toll on wild populations, the principal threat to Siamang is habitat loss in both Malaysia and Sumatra. Palm oil production is clearing large swathes of forest, reducing Siamang habitat, along with other species such as the Sumatran Tiger. The Siamang can be twice the size as...

The bonobo (Pan paniscus), until recently is usually called the pygmy chimpanzee and less often the dwarf or gracile chimpanzee. It is one of the two species of chimpanzees. Physical characteristics Its head is smaller than that of the Common Chimpanzee but has a higher forehead. It has a black face with pink lips, small ears, wide nostrils, and long hair on its head. Females have slightly prominent breasts in contrast to the flat breasts of other female apes, though not as prominent...

The common chimpanzee (Pan troglodytes), also known as the robust chimpanzee, is a great ape. Basic facts Common chimpanzees are found in the tropical forests and wet savannas of Western and Central Africa. They once inhabited most of this region, but their habitat has been dramatically reduced in recent years. Adults in the wild weigh between 88 and 143 lbs (40 and 65 kg). Males can measure up to 63 inches (160 cm) and females up to 51 inches (130 cm). They are lighter than humans...

The Sumatran orangutan (Pongo abelii) is the least common of the two species of orangutans. It lives on the Sumatra island of Indonesia. They are smaller than the Bornean orangutan. Baby Sumatran orangutans are often poached as highly prized Zoo Inhabitants. The poachers often kill the baby's mother for no apparent reason. The Sumatran Orangutan is only found north of Lake Toba.
