"Not only do proteins survive, but they survive in sufficient quantities to enable resolving the evolutionary relationships between Giganto and extant great apes," Welker added, referring to the group that includes orangutans, gorillas, bonobos and chimpanzees.
|
|
The minders take pains not to be overly affectionate with their adorable charges: The orangutans need to learn to avoid humans and not be accustomed to their presence, in preparation for their return to the jungle.

Dwarfed by today's gorillas, chimpanzees and orangutans, the miniature ape was possibly a casualty of natural selection, unable to compete with colobine monkeys that dined on the same leaves in trees some 12.5 million years ago.
|
|
In this lesson, we present students with an environmental quandary to discuss and debate — a case study about the best way to protect orangutans given the wave of deforestation shrinking their natural habitat in Southeast Asia.
|
|
Of course, I got the dragon bit totally wrong and we'd soon learn that the other wildlife we'd encounter — the orangutans, the scops owls, the unjustly athletic gibbons and hypnotizing manta rays — was infinitely more interesting.
|
|
In the same period, approximately three quarters of Borneo's rain forests have been converted for human purposes, mainly into industrial agriculture or coal mining areas, leaving orangutans little choice other than starvation or eating from human plantations.
|
|
The zoo near the Dutch border said its entire ape house burned down and more than 30 animals — including five orangutans, two gorillas, a chimpanzee and several monkeys — were killed, as well as fruit bats and birds.
|

But environmentalists fear the move will hasten the destruction of forests that are home to orangutans, sun bears and long-nosed monkeys, as well as increasing pollution already on the rise from coal mining and palm oil industries.
|
|
" Apparently all the lady orangutans have to do is just pick someone attractive and then the mate arrives at their door without any fuss or dating, giving an entirely new meaning to the phrase "monkey see, monkey do.

Environmental groups raced to the scene in West Kalimantan province, on the island of Borneo, to find a charred wasteland: smoldering fires, orangutans driven from their nests, and signs of an extensive release of carbon dioxide into the atmosphere.
|
|
Sabah's government says it is committed to striking a balance between economic development and preserving Borneo's extraordinary natural heritage, including by designating extensive areas of forest as nature reserves for threatened orangutans and creating Malaysia's largest marine protected area.
|
|
It was not until 2013, when the adult male skeleton became available, that scientists realized how unique the population was, which sparked the largest genomic study of wild orangutans ever carried out to provide further evidence of a third orangutan species.
|
|
Through research out of the Tuanan Orangutan Research Station in the Mawas Conservation Area on wild orangutan behavior, a curriculum was developed to help the orphans learn the same behaviors that wild orangutans use to survive in the forests of Borneo.
|

Mr. Stiles knew what Tom was hoping for: to sell the infant orangutans to a private collector or unscrupulous zoo, where they are often beaten or drugged into submission and used for entertainment like mindlessly banging on drums or boxing one another.
|

"The roughly 2.6 million-hectare Leuser Ecosystem in Sumatra is renowned around the world by scientists, conservationists and wildlife lovers as the only place left where critically-endangered orangutans, tigers, elephants and rhinos still exist in the same forest," RAN said in its report.
|
|
"The decline in population density was most severe in areas that were deforested or transformed for industrial agriculture, as orangutans struggle to live outside forest areas," said a lead researcher for the study, Maria Voigt of the Max Planck Institute for Evolutionary Anthropology in Germany.
|
|
"Orangutans are flexible and can survive to some extent in a mosaic of forests, plantations and logged forest, but only when they are not killed," said Serge Wich, a professor at Liverpool John Moores University in Britain and a member of the research team.
|
|
Next, they should decide what they would do in this situation if they were environmentalists trying to protect orangutans and address these key questions: • Should the Borneo Orangutan Survival Foundation accept funding from a major Indonesian palm oil company to support its orangutan refuge?
|

"If we want a world with orangutans and puffins, clean air and enough food for everyone, we need urgent action from our leaders and a new global deal for nature and people that kick starts a global program of recovery," Steele said in her statement.
|
|
Correction: An earlier version of this article implied that chimpanzees ran the government depicted in 1968's Planet of the Apes and its sequels when in fact political authority was vested in orangutans and chimpanzees served as a kind of scientist and intellectual caste.
|
|
The research is based on analysis of the skeleton of an adult male killed in a conflict with villagers, a genetic study indicating the population&aposs evolutionary split from other orangutans occurred about 20063 million years ago, and analysis since 2006 of behavioral and habitat differences.
|

"Orangutans, in some instances, also exhibit annual cyclicity in the rate at which they acquire developmental defects of tooth enamel—areas of deficient enamel that result from physiological stress, such as undernutrition or disease, occurring during the period of tooth formation," she told Gizmodo in an email.
|
|
Forest cover on Indonesia's Sumatra island, home to endangered tigers, orangutans and elephants, had declined by more than half to 11 million hectares in 2016 from the 25 million hectares it had in 1985, as palm oil and other plantations have expanded and encroached on protected areas.
|
|
They were surprised to find singular characteristics that consistently differed from other Sumatran orangutans, including in the measurements and overall shape of its skull, jaw and teeth, said Matthew G. Nowak, a conservation biologist with the Sumatran Orangutan Conservation Program, an organization involved in the research.
|
|
"They say there is a moratorium, but I can see with my own eyes that land is being lost every day," said Krisna, a coordinator for the Human Orangutan Conflict Response Unit, a group based on Sumatra that has rescued more than 170 injured orangutans since 2012.
|
|
The series presents a lot of no-brainer solutions to show how populations can bounce back, like developing marine reserves to solve overfishing and restoring jungles where orangutans that have evolved to use tools like sticks (for finding and eating their food) are now at risk.
|
|
The Southeast Asian rain forests orangutans call home are challenging environments, with unpredictable booms and busts in fruit, the animals' most important food, said Tanya Smith, an associate professor in the Australian Research Center for Human Evolution at Griffith University and an author of the paper.

Or one particularly crafty mammal from the annals of history: the Harry Houdini of orangutans, with the unassuming name of Ken Allen, who rose to fame in the 1980s for escaping the San Diego Zoo not once, not twice, but thrice — sometimes colluding with other primates.
|

The discovery suggests that bipedalism originated in a common ancestor of humans and the great apes - a group that includes chimpanzees, bonobos, gorillas and orangutans - that inhabited Europe rather than an ancestor from Africa, the continent where our species Homo sapiens first appeared roughly 300,000 years ago, the researchers said.
|
|
The findings, which were published in the journal Scientific Reports, challenge the notion that orangutans — an endangered species that shares about 97 percent of it DNA with humans — make noises simply in response to something, sort of like how you might scream when you place your hand on a hot stove.
|
|
As research continues to reveal the breadth of our genetic, emotional and cognitive kinship with the world's four great apes — gorillas, chimpanzees, bonobos and orangutans — many primatologists admit to feeling frankly uncomfortable at the sight of a captive ape on display, no matter how luxe or "natural" the zoo exhibit may be.
|
|
"Wild chimpanzees, gorillas, bonobos and orangutans all use gestures to communicate their day-to-day requests, but until now there was always one ape missing from the picture—us," explained Catherine Hobaiter, a senior author of the paper and a scientist at the School of Psychology and Neuroscience at the University of St Andrews.

If John is savvy enough to look up ape-related stories on the Internet, such as how mother orangutans teach their babies to avoid poisonous fruit and, more ominously, how a pet chimpanzee escaped and was shot by the police, how could he not run across information on the dangers of keeping apes in the house?
|
|
According to The Telegraph, the Borneo Orangutan Survival Foundation, a non-profit group dedicated to conserving the Bornean orangutan population, is caring for 37 young orangutans "suspected to have contracted a mild respiratory infection" from air pollution caused by the fire, at their rehabilitation center located near the capital city of the Indonesian province of Central Kalimantan.
|

However, when experienced field workers who follow apes around in the tropical forest tell me about the concern chimpanzees show for an injured companion, bringing her food or slowing down their walking pace, or report how adult male orangutans in the treetops vocally announce which way they expect to travel the next morning, I am not averse to speculations about empathy or planning.
|

From Rutherford's myriad examples — leaf-cutter ants that produce a "pesticide" to protect the leaves they rely on to nourish their food source; Australian "firehawks" that spread bush fires to flush out prey from burning grasses; orangutans that use branches as sex toys — it becomes apparent that much of what we may think to be uniquely human is, in fact, not.
|
|
Previously, researchers estimated that orangutans wean off maternal milk between 6 to 8 years old, but they could never be sure because field surveys of the animals are tricky: Offspring often suckle inconspicuously, high up in trees or at night, and even when suckling is observed, it's hard to know whether the animals are consuming milk or just comfort nursing, with no milk transfer.
|
