The newly discovered excavations revealed

Researchers discovered excavations belonging to an old, old, unknown relative. Perhaps they lived at the same time and the location of the well -known members HomoAnd from which modern humans developed, according to a new study.

A team of archaeologists working in the Lidaro Research Project in Ethiopia has discovered a set of fossilized teeth that are likely to belong to an unknown type inside Australopithecus Sex, known as human and monkey -like features. The results are published in nature.

To date, scientists have discovered six Australopithecus Types in sites in Africa, including the famous Lucy fossil. But not all of these types intersect with our oldest human ancestors Homo.

The history of the newly found teeth, from two people, dates back to 2.6 to 2.8 million years. While they share some characteristics with others Australopithecus Species and comparisons with nearby fossils and other hominin samples indicate that they are distinct enough to be considered a new type.

On the same location, scientists have also discovered three other teeth that are likely to belong to members of the oldest species HomoWhich dates back to 2.59 million years. This type was first determined in 2013 through the jaw bone in the same study site.

These discoveries indicate that up to four early human strains-Homoand paranoiaand Australopithecus garhiAnd the newly identified species – have coexisted in East Africa between 2.5 and 3.0 million years.

“This new research indicates that the image that many of us possess in our minds from the monkey to Neanderthal for modern man – the development does not work like this,” said Kay Reed, an old doctor at Arizona State University. statement. “We have two types of hominin together. Human development is not written, it is a dense tree, and there are forms of life that is extinct.”

Researchers need more fossils of species to give them an official name. But now Australopithecus.

It is still ambiguous that these first grandparents are still a mystery, but they can eat different things and did not compete for the same resources. Scientists are currently studying the newly discovered teeth enamel to know what these types may have.

“Whenever you have an exciting discovery, if you are a field doctor, you always know that you need more information,” Reid said in a statement. “You need more fossils. For this reason, it is an important field for training people on people, finding their own sites, and finding places that we have not yet found.”
