By utilizing historical protein sequencing, researchers have retrieved genetic data from a 1.9 million-year-old extinct, enormous primate that used to live in a subtropical area in southern China. The genetic data permits the researchers to uncover the evolutionary place of Gigantopithecus blacki, a 3-meter tall and probably 600 kg primate, revealing the orangutan as its closest living relative.
It’s the first time that such outdated genetic materials have been retrieved from warm, humid surroundings. The examine is revealed within the scientific journal Nature, and the outcomes are ground-breaking inside the area of evolutionary biology, based on Frido Welker, Postdoc on the Globe Institute on the Faculty of Health and Medical Sciences and first author of the research.
“Primates are comparatively close to humans, evolutionary speaking. With this examine, we present that we will use protein sequencing to retrieve historic genetic info from primates living in subtropical areas even when the fossil is two million years outdated. Till now, it has only been potential to retrieve genetic data from as much as 10,000-year-old fossils in heat, humid areas. That is interesting, as a result of historic stays of the supposed ancestors of our species, Homo sapiens, are additionally primarily present in subtropical areas, particularly for the early a part of human evolution. This means that we can potentially retrieve related data on the evolutionary line resulting in people,” says Frido Welker.
Today, scientists know that the human and the chimpanzee lineages split around seven or eight million years in the past. With the earlier methodologies although, they might only retrieve human genetic info not older than 400,000 years.
