Various scientists from Australia have managed to extract the oldest DNA from several fossils of two huge giant marsupials. It is believed that they inhabited the country about 40,000 years ago and as researchers have reported, the process has been truly difficult although they are happy because they have clarified the family tree of kangaroos and modern wallabies.
Bastien Llamas, a researcher at the Australian Center for Prehistoric DNA at the University of Adelaide, has stated that “The possibility of extracting DNA to analyze it has been something of great importance in this study, since previous work in Australia has not been able to be carried out in depth”.
A large amount of genetic material extracted from the remains of skulls and also from the teeth that have been found in a cave in the Tazmania area, which have turned out to be of a Sismostherenus occidentalis or giant kangaroo and a Protemmodon anak, of the giant wallabie, who lived about 40,000 years ago.
Llamas, an expert in genetic biology, assured that the problem in this country with which there are many investigations that have DNA extraction as one of their guidelines, are the high temperatures and also the humidity that exist in many areas of the country, which means that the genetic material is not preserved as in many other places in the world and it is a very difficult task and therefore, when results are obtained it is a joy for the scientific community.
He also wanted to add that many of Australia's prehistoric fauna species that have been extinct for a long time, today lack close relatives that can be known or simply, the true existence of possible ties is unknown.
In this research it has been found that the giant wallabie is directly related to modern kangaroos. It has also been confirmed that the giant kangaroos when they disappeared did not leave offspring, but it is known that their lineage could be related to the Lagostrophs fasciatus, a species of wallabie.
One of the objectives of studying these findings is that It will be possible to determine what or what were the reasons for the extinction of both the wallabies and the giant kangaroos. Llamas has confirmed that he will continue with his studies to investigate more about this finding, but he will take advantage of and also extend the research to other species of marsupials such as the marsupial lion or the diprotodon among others.
After studying History at the University and after many previous tests, Red Historia was born, a project that emerged as a means of dissemination where you can find the most important news of archeology, history and humanities, as well as articles of interest, curiosities and much more. In short, a meeting point for everyone where they can share information and continue learning.
