Even some hobbits. A new species of human

In a cave in the Philippines found a new kind of man

Homo luzonensis combine features of several types of people, as well as more ancient hominin – Australopithecus and paranthropus.

On the Philippine island of Luzon found the remains of at least three extinct humans unknown species called Homo luzonensis. They lived over 50 thousand years ago and combines as a progressive traits of the modern man and the ancients, typical of Australopithecus.

As Homo luzonensis appeared on the island and what types of extinct humans was their closest relatives remains to be seen. Корреспондент.net tells details.

 

Contradictory kind of person

A group of scientists under the leadership of Florent Detroy from the National Museum of natural history in Paris and Armand Salvador Mijares of the University of the Philippines presented a number of findings in the publication Nature.

They said the new species of man based on the remains of the feet, hands, teeth and upper thigh. These skeletal fragments are fundamentally different from other remains of ancient man.

People have lived on Luzon in the Pleistocene. Last year scientists reported the discovery on the island of stone tools and bones of a rhinoceros with signs of butchering with stone tools about 700 thousand years ago. Prior to that, the oldest inhabitants of the island were regarded as people who lived in a cave Callao at least 67 thousand years ago.

Morphologically, the remains of the combine features of several types of people, as well as more ancient hominin – Australopithecus and paranthropus. In particular, the premolars of H. luzonensis in size and shape resembled as the molars of the Australopithecines and paranthropus.

Scientists have tried to extract from the remains of DNA to determine the sequence of the genome. But, as in the case with the skeletons of other ancient people, found in the tropics, attempts have not crowned success.

Its small size and primitive they strikingly resemble the skeleton of representatives of human Florensky (Homo floresiensis) from the Indonesian island of Flores, which got its informal name based on the novel by J. R. R. Tolkien’s the Hobbit.

But in terms of the anatomical parts the Luzon and Floresti hobbits differ from each other so that they cannot be defined as members of the same species, the researchers note. In General, Detroi, Mijares and colleagues were unable to answer the question of how both findings fit into the family tree of mankind.

Some parts of the skeleton are suitable even more reasonable person than another possible relatives, which really can not be, because at that time modern man has not made it to Flores island or Luzon.

The remains of autralopithecus person lessonsare and human Florensky resemble various species of Australopithecus that many millions of years ago inhabited Asia and South Africa. In addition, there are similarities with massive fossil paranthropus and Homo habilis. People lysonski a bit, but could climb trees, this is indicated by the curved hand and foot.

Leave Africa, Homo erectus had lost many of their ancient characteristics.

It can be concluded that this representative of the genus homo moved from South Africa and reached Asia. It is possible that his ancestors, existed until the latest time as contemporaries of the Asian Homo erectus, denisovans, and, eventually, anatomically modern humans. And of course, the representatives of all those populations who are still waiting to be discovered.

In order to go a long journey and settle in the new world, apparently, did not have pronounced the current behavior, and apparently were not Homo erectus. For anthropologists this means that we have to rethink the old model of interpretation of human history.

 

The riddle of the hobbits of Flores

In 2015, scientists have found that the controversial hominids from the Indonesian island are a separate species of people, not CRO-magnons degenerate with developmental defects as previously thought.

The remains of ancient people, which the press almost immediately called “hobbits”, found on the Indonesian island of Flores in 2003. In October 2004, the team of Michael Morwood introduced the world to the skull and nearly complete skeleton of an ancient man the height in meters.

The lack of new fossils has led many scientists to believe that hobbits were ordinary people who turned into dwarfs because of these abnormalities, such as microcephaly, Laron syndrome, cretinism and other disabilities.

But, as shown by their analysis, the teeth of Homo floresiensis have been arranged much simpler than ours. Some of them klyovye premolars – were more similar in structure to what looked like the same teeth late erectus people who lived in Asia and Europe in the late Pleistocene.

Overall, the hobbit was closer to the device’s teeth to Homo erectus than to CRO-magnons, and put them in a separate type generated by the “island dwarfism”.

In 2018, scientists described in the journal Science that people of small stature appeared on the Indonesian island of Flores at least twice, independently from each other. It was hobbits and modern pygmies.

It turned out that Florensky pygmies are genetically similar to Neanderthals and denisovans, but traces of other kinds of people in their DNA, scientists have not identified.

In addition, the researchers found snips in the genes FADS1 and FADS2, coding Germany metabolism of fatty acids. It is known that mutations in these genes have repeatedly and independently appeared in modern populations in different parts of the world.

According to the researchers, this suggests that the ancient hobbits and modern pygmies evolved twice, independently from each other.
