How the Largest Primate Ever Went Extinct

The largest primate in our family tree went extinct hundreds of thousands of age ago , and its existence has been cognise to humankind for less than a hundred . Now , a team of researchers has reviewed the ancient records and devised a more specific defunctness window for our huge fallen relative , Gigantopithecus blacki , and pointed out a few potential causes for its death .

The aper function out between 295,000 and 215,000 days ago , according to the unexampled sketch . As the climate of southeast Asia vary , G. blacki could not change its eating habit or home ground . Its geographical footprint diminished , and before long , only fossilized teeth remained . The novel enquiry ispublishedtoday in Nature .

“ The story of G. blacki is an enigma in palaeontology — how could such a mighty creature go out at a prison term when other primate were adapting and hold out ? ” enunciate lead author Yingqi Zhang , a paleontologist at the Institute for Vertebrate Paleontology and Paleoanthropology at the Chinese Academy of Sciences , in a affirmation . “ The unresolved case of its disappearance has become the Holy Grail in this discipline . ”

The search for the largest archpriest to ever exist begin in 1935 , when a German palaeontologist happened upon a “ dragon ’s tooth ” in a Hong Kong apothecary . It was a grinder — not of a dragon , obviously , but an extinct ape , one that is estimated to have endure nigh 10 feet ( 3 measure ) improbable and weighed up to 661 pounds ( 300 kilograms ) .

short grounds of G. blacki remains , tucked aside in caves in southeasterly Asia . The ape ’s fossil record is comprised of four lower jaw and 2,000 dentition , the recent squad reports . But their work thrive the fossil record , drawing on newly hear corpse turn up from cave between 2017 and 2020 . Prior to that , Zhang had encounter six caves contain G. blacki remains over the course of a decennary . Twenty - two cave were taste for the recent paper , and six dating techniques were used to corroborate the timeline of the aper ’s extinction .

Besides the fossil remains , the team look at ancient pollens , sediments , and isotopes shut up off in the cave flooring , to understand the changing climate G. blacki was facing . Other emulator face it , too , include one of the giant anthropoid ’s closest relatives , Pongo weidenreichi , an ancient species of orangutan .

The research worker determined that , as the clime change , G. blacki did n’t adapt like its congener in the region . As its food rootage became unavailable due to the alter climate — the forest and grass ecosystem gave agency to an capable wood environment — G. Blacki resorted to less nutrient foods .

“ G. blacki was the ultimate specialist , compared to the more agile adapters like orangutang , and this ultimately led to its demise , ” Zhang said .

Though P. weidenreichi also depart extinct , it did soaround 60,000 years ago — much more latterly than the giant copycat with which it share southern Asia . And of course , three orangutan species stay extant , althoughall are critically menace .

“ realize the causes of primate extinction is of the essence with the terror of a sixth mass extermination event looming over the planet , ” said co - lead generator Kira Westaway , a geochronologist at Macquarie University , in an electronic mail to Gizmodo . “ kick the bucket back to preceding unresolved extinction and determining the causes helps us understand specie responses to environmental stresses . This has massive implications for our animation order Primates such as New orangutang and mountain gorillas . ”

The climate is interchange , and expectant apes are lose habitat due to human activities — husbandry , excavation , and logging amongst them , according to the World Wildlife Fund . The orangutan is the only great anthropoid left in Asia , and it is being promote to extinction bypalm oil producers .

It ’s light to rue to loss of G. blacki , an animal of tremendous weighing machine , but it will be even more sore to lose metal money we ’re conversant with — which is why a global reply to clime change is so all important .
