Dritte Orang-Utan-Art beschrieben



my name is Michael Hudson I'm professor for evolutionary anthropology and genomics at the University of Zurich and I've been working on orangutans since my arrival here in Zurich which was you know more than a decade ago my group but also with collaborators you know from from multiple international institutions from Indonesia from the u.s. from the okay from Spain and other countries revealed you know that they're actually not two orangutan species but three orangutan species when you look at the animals just you know if you look at the fur there they seem to be slightly different but that probably would not be enough to call them a novel species so there are significant differences in the skull morphology and in the dental morphology of these orangutans when we brought together the genomic evidence and the morphological evidence it became clear that the orangutans from bottom to go from this isolated population constitute a new great ape species some very complex modeling based on whole genome data showed that they're actually three independent evolutionary lines the new species is called Huang would happen early enza's it occurs at the southern tip you know where orangutans live in in Sumatra in a place called button too-hoo it's a small isolated population of only about eight hundred individuals orangutans came to what's now Sumatra from from mainland Asia and the button to rule population was a new species Pongo tapa new lenses they are direct descendants of the first orangutans that settled in this area the new species occurs in a special habitat it's a Highland a habitat it's quite isolated very hard to get to as a researcher it's you know dense rainforest canopy but it's unusual because lots of orangutans in Sumatra occur in in swamp forests the bernoulli orangutan does not occur in swamp it's mountainous rugged area and it's very hard for researchers actually to go and study these individuals and this is also one of the reasons why I guess that population was fog has been forgotten for a long time there were reports of this population in the 1930s but then kind of got forgotten and it was only rediscovered in 1997 we also have to keep in mind there's only 800 individuals left of these orangutans so I really do hope that with our work we will be able to provide enough information for non-governmental organizations but also you know for for governments in local governments in in northern Sumatra and in Indonesia to protect the species
