Island in South East Asia May Hold the Key to Humanity is interbreeding

Those whose predecessors came from the eastern islands of Southeast Asia bear extensive evidence of interference with the Denisovans. However, three other members of the human family living in the area have not identified Homo erectus, Homo floresiensis and the recently discovered Homo luzonensis. 

Yet, the presence of these other human species has probably left an important legacy in the survival of some large animals. Some genes in most modern human Neanderthals sent shock waves through anthropological discoveries. Evidence of further local inheritance of the Denisovans then found, a branch of early humanity known only from a few fist bones and DNA preserved in cocoon sediments. 

The obvious question was whether any ancestral branch of the human family lived among us. Some evidence of this has found, but we know almost nothing about whom they or what happened. The most promising place to look for such a contribution to the human genome is on the islands that now comprise eastern Indonesia, the Philippines and New Guinea. Two human species, h. Fluorescence (nicknamed “Hobbits”) and h. luzonensis known only from the islands that give them their name and probably survived long enough to face the first modern human arrivals. Extensive travel h. Erectus once called Java man after the initial discovery site.

The fact that no surviving DNA has recovered from any of the fossils of this species hinders us from identifying their inheritance. These analyzed with human rights in search of sequences that could a branch of the human family that was distracted from modern humans much earlier than the Denisovans, before interbreeding brought it back.

In natural ecology and evolution, taxis and co-authors have declared this method that they have not revealed any sign of “super-archaeological” hominin DNA, for example no hobbit-DNA of the inhabitants of Flores. On the other hand, the study confirmed that the previous report found that the highest proportion of Denisovans genetics in the world was among Indigenous Australians and New Guineans, with the nearby islands not far behind.

Teixeira said in an emailed statement, “The level of Denisovans DNA in contemporary populations indicates that the island has reproduced significantly in Southeast Asia.”  “The mystery still remains, why have we not found their fossils along with other ancient peoples in the region? “Professor Chris Helgen, co-author of the Australian Museum Research Institute, told IFLScience that the Denisovans probably crossed the Wallace Line, where the island radically changed the flora and fauna of Southeast Asia.

When modern humans arrived in the region, they probably encountered several human species, but only bred successfully with the Denisovans. Perhaps others also seemed too alien as attractive mates, or were too biologically different for mating to produce fertile offspring. Nevertheless, Helgen thinks that the presence of humans before us can detect the large animals of these islands against these predatory techniques and give them the opportunity to adapt to less sophisticated technology.

This would explain why species such as the Komodo dragon and the Philippine buffalo survived the advent of modern humans without the Australian defense. Helgen told IFLScience that people on the island were not very likely to be detached from the Denisovan line because of physiological differences. Instead, the islands seem to have been the meeting place of many branches of humanity. He added that there is a lot of evidence that Sulawesi is the most likely place to find evidence of this kind of conflict, making the island one of the most interesting places in the world for paleoanthropology.
