A pair of ancient skeletons represent the same kinds of human ancestor, scientists confirm

A couple of ancient skeletons thought to represent two different humanity ancestors are actually of the same kind, scientists acknowledge

  • Old male and female female bones were found in Malapa in 2008
  • They were the first thought to be the same, but later suggested they were not
  • New research on 135 fossils has now confirmed that they are of the same kind
  • Researchers say they represent different stages of growth in both species of sedi

New research on a couple of million-year-old skeletons is helping to strengthen the timeline of human evolution.

After two partial skeletons were found at a South African site known as the humankind's cradle a decade ago, the debate raised whether they were of the same kind, or represented two different human ancestors.

Now, a series of studies meticulously analyzing the remains of this issue.

Despite clear differences in some bone structures, researchers say that these two skeletons are, in fact, the same species – they simply represent two different stages of growth.

According to the researchers, these discrepancies were noted in the lumbar vertebrae of the two promoters as one was an individual and the adult was quite mature.

Research from several universities published a total of nine papers in a special issue published by the Paleoanthropology magazine this month investigating the two ancient skeletons.

Juvenile male bones (MH1) and adult females (MH2) were found in the Malapa fossil site back in 2008.

At that time, Lee Burger and colleagues named a new huminin, discovered at the find: Australapapathecus Sediba.

Several years later, however, a research group suggested the two men could not be of the same species, due to differences in their lumbar vertebrae.

An elusive 135-fossil analysis has now allowed researchers to outline the body's proportions and walk the two long-assembled human ancestors along with their skull, verbal, and other parts.

And, they say the two people are both types of sedi.

Our interpretations in this paper suggest that Ye Sediba was adapted to terrestrial bipedalism, but also spent significant time climbing in trees, perhaps for predators and protection of predators, says New Anthropologist New York Scott Williams, who focused on On the axial skeleton – the vertebrae, ribs, and sternum.

The larger image was transmitted lightly to a sedibody's livelihood, as well as a major transition to huminine evolution, including the vast majority of IIPE-like in the Australopithecus garden in former members of our own family, Homo.

The Bones of the Youth (MH1) and Adult Female (MH2) were found in the fossilized site of Malapa back in 2008. The South African site is within an area known as the Cradle of Humankind.

When one of the first emerald people dies?

The timeline of human evolution can be traced back to millions of years. Experts estimate that the family tree goes as follows:

55 million years ago – First primitive primates evolve

15 million years ago – Jininidae (Great Apes) evolve from the ancestors of the gibbons

Seven million years ago – First Galilee Evolve. Later, chimp and human lines are diverse

5.5 million years ago – Ardipithecus, Free & # 39; Prototype & # 39; Shares traits with chimps and gorillas

4 million years ago – Ape as early as humans, the Australopithesines appeared. They have no intelligence more than a chimpanzee's but other people like features

3.9-2.9 million years ago – Australoipithecus afarensis lived in Africa.

2.7 million years ago – Paranthropus, lived in the woods and has massive jaws for chewing

2.6 million years ago – Hand axes become the first major technological innovation

2.3 million years ago – Homo habilis first thought to be in Africa

1.85 million years ago – the first & # 39; modern & # 39; Hand emerges

1.8 million years ago – Homoergaster begins to appear in fossil record

800,000 years ago – Early humans control fire and make herds. Brain number increases rapidly

400,000 years adOh – First-time renegades begin to appear and spread across Europe and Asia

300,000 to 200,000 years ago – Homo sapiens – modern humans – appear in Africa

50,000 to 40,000 years ago – Modern humans reach Europe

According to the researchers, these discrepancies in the lumbar vertebrae of the two promoters were noted because one was an individual and the other was a fully-grown adult.

& # 39; the differences in the verbs can simply be attributed to their development of the older differences: Youth's Youth & # 39; Verbrae's growth is not yet complete, but growth in viral growth is complete, Williams said.

"As it happens, the two Homo Erectus skeletons are Juvenile, so Mh1 looks more like them because it is also a jewel."
