Males are considered the most solitary of the orangutans. The Bornean orangutan has a lifespan of 35–45 years in the wild; [2] in captivity it can live to be about 60. [25] Despite being arboreal, the Bornean orangutan travels on the ground more than its Sumatran counterpart. This may be in part because no large terrestrial predators could ...
A 2017 genome study found that the Bornean and Tapanuli orangutans diverged from Sumatran orangutans about 3.4 mya, and from each other around 2.4 mya. Millions of years ago, orangutans travelled from mainland Asia to Sumatra and then Borneo as the islands were connected by land bridges during the recent glacial periods when sea levels were ...
Orangutans have a median life expectancy of 37.6 years in professional care, according to the zoo. Reaching the half-century milestone makes Dumplin the third-oldest Bornean female orangutan in ...
The researchers also published less complete copies from ten wild orangutans, five from Borneo and five from Sumatra. The genetic diversity was found to be lower in Bornean orangutans (Pongo pygmaeus) than in Sumatran ones (Pongo abelii), despite the fact that Borneo is home to six or seven times as many orangutans as Sumatra. The comparison ...
"Bornean Orangutans decreased by more than 60% between 1950 and 2010, and a further 22% decline is projected to occur between 2010 and 2025," the organization explains, which "equates to a loss of ...
A century ago, there were probably more than 230,000 orangutans in total, but now, the organization states the Bornean orangutan is estimated at about 104,700 (classified as endangered) and the ...
Until well into the 19th century, juvenile orangutans were taken from the wild and died within short order, eventually leading naturalists to mistakenly assume that the living specimens they briefly encountered and skeletons of adult orangutans were entirely different species. [5]
However, the discovery of a previously unknown orangutan population in Malaysian Borneo is reason to hope. Threats. Human actions have reduced orangutan habitats by more than 80% over the past 20 ...
