One of the new Homo naledi skulls unearthed by Hawks, Berger, and their colleagues. The materials were found deep in a South African cave system in , adding H. Last year, scientists performed phylogenetic analyses that pegged the age of the H. Since then, the scientists who originally unearthed the fossils have suggested that the remains could be hundreds of thousands of years younger. The findings suggest that H. They also throw a wrench into theories that modern humans alone left behind a rich record of stone tools in Africa as their large brains developed new technologies and techniques for making a living in a harsh environment.
Meet Homo naledi, our long-lost human cousin
A recent paper published in the journal eLife shows that this new species lived between , and , years ago in South Africa. Yesterday 9th of May , the journal eLife published the results of a multidisciplinary dating work revealing for the first time that Homo naledi lived between , and , years ago in South Africa. Based on the combination of a wide range of methods such as Luminescence, Palaeomagnetism, Electronic Spin Resonance ESR and Uranium-Thorium Series, this work enables for the first time to obtain a reliable date for this new species discovered and published by the paleoanthropologist Lee R.

New ages for flowstone, sediments and fossil bones from the Dinaledi Chamber are presented. We combined optically stimulated luminescence dating of sediments with U-Th and palaeomagnetic analyses of flowstones to establish that all sediments containing Homo naledi fossils can be allocated to a single stratigraphic entity sub-unit 3b , interpreted to be deposited between ka and ka. This result has been confirmed independently by dating three H. We consider the maximum age scenario to more closely reflect conditions in the cave, and therefore, the true age of the fossils.
By combining the US-ESR maximum age estimate obtained from the teeth, with the U-Th age for the oldest flowstone overlying Homo naledi fossils, we have constrained the depositional age of Homo naledi to a period between ka and ka. These age results demonstrate that a morphologically primitive hominin, Homo naledi, survived into the later parts of the Pleistocene in Africa, and indicate a much younger age for the Homo naledi fossils than have previously been hypothesized based on their morphology.

Homo naledi: Another Failed Evolutionary Ape-Man
Dating of Homo naledi fossils from the Dinaledi Chamber of the Rising Star cave system, South Africa, shows that they were deposited between about , and , years ago. Species of ancient humans and the extinct relatives of our ancestors are typically described from a limited number of fossils. However, this was not the case with Homo naledi. More than 1, fossils representing at least 15 individuals were unearthed from the Dinaledi Chamber of the Rising Star cave system in After the discovery was reported, a number of questions still remained.
The material was undated, and predictions ranged from anywhere between 2 million years old and , years old.

The newly discovered species, Homo naledi, is believed to have lived alongside early humans known as Homo sapiens. The latest specimens include remains of two adults and a child. One of the adults’ skull is reportedly complete. The new discovery comes barely a year and and a half after scientists announced in South Africa the discovery of the richest fossil hominin site on the continent, unveiling a new species named Homo naledi.
Although they had primitive small-brains, an extensive dating process has found that the Homo naledi species were alive as early as , years ago. Professor Paul Dirks of James Cook University said in a statement that dating the existence of these Homo naledi was extremely challenging. With 19 other scientists from laboratories and institutions around the world, he managed to date it to a period known as the late Middle Pleistocene. Two years ago, researchers found that Homo naledi people had deliberately disposed of their dead in a private chamber in caves, a behavior which until now was thought to be exclusive to modern humans.
The new discovery and research was conducted by a team of researchers from the University of the Witwatersrand in South Africa, James Cook University in Australia, the University of Wisconsin Madison in the United States, and more than 30 additional international institutions.

Dizzying New Evidence In Human Evolution Provokes Debates
New discoveries and dating of fossil remains from the Rising Star cave system, Cradle of Humankind, South Africa, have strong implications for our understanding of Pleistocene human evolution in Africa. Direct dating of Homo naledi fossils from the Dinaledi Chamber Berger et al. Hawks and colleagues Hawks et al. Previously, only large-brained modern humans or their close relatives had been demonstrated to exist at this late time in Africa, but the fossil evidence for any hominins in subequatorial Africa was very sparse.
It is now evident that a diversity of hominin lineages existed in this region, with some divergent lineages contributing DNA to living humans and at least H.

Discovered in a South African cave, H. Though the remains were undated at the time, estimates put them at anywhere from , to several million years old. This was based on a physical analysis of the bones, which contained a curious mixture of modern and archaic traits. Now, after putting the remains through a rigorous series of tests, Berger and his coauthors have shown that these individuals lived between , and , years ago, co-existing, at least for a time, with modern humans.
Homo Naledi Likely Coexisted With Humans
The CENIEH participates in the first dating study which demonstrates that this new species lived between , and , years ago in South Africa.

A meticulous dating process showed that Homo naledi nah-LEH-dee , which had a mix of human-like and more primitive characteristics such as a small brain, existed in a surprisingly recent period in paleontological terms, said Prof. Lee Berger of the University of the Witwatersrand in Johannesburg. Berger led the team of researchers, which also announced that it had found a second cave with more fossils of the Homo naledi species, including a relatively well-preserved skull of an adult male.
The research was also published in the journal eLife. The fossils were found in the Rising Star cave system, which includes more than 2 kilometres 1. The second chamber containing the more recent fossil discoveries is more than metres feet from the cave where the original discoveries were made, and publicly announced in Some experts who were not involved in the research also marvelled at the age of the fossils, determined by dating Homo naledi teeth and cave sediments.
Berger, the research team leader, said the discovery of a second chamber with Homo naledi remains gives more credence to the idea that the species deliberately disposed of its dead in pitch-black caves that are extremely difficult to reach. However, some experts who were not on the research team questioned whether the small-brained species was capable of such behaviour and speculated that other ways to access the chambers may have existed in the past.
So far, there is no evidence that Homo naledi used stone tools or harnessed fire for its own uses. The new discoveries offer a unifying message that counters populism, intolerance and ethnic prejudice sweeping many parts of the world, said Adam Habib, vice-chancellor of the University of the Witwatersrand.

Amazing haul of ancient human finds unveiled
The remains of at least 15 individuals were found in the Rising Star cave system in South Africa and announced as a new human species in The remains are the largest assemblage of a single hominin species yet discovered in Africa. Homo naledi combines primitive with modern features and is not a direct ancestor of modern humans. The remains date to between about , and , years ago. This does not represent the timespan for this species, merely the age for a limited number of fossils.
It is likely that this species first appeared much earlier, possibly as even 2 million years ago.
Newly obtained dating of the fossil hominin species Homo naledi, which was first discovered in , significantly alters its position in the overall.
All rights reserved. A year and a half after adding a puzzling new member to the human family tree , a team of researchers working in South Africa have offered an additional twist: the species is far younger than its bizarrely primitive body would suggest, and may have shared the landscape with early Homo sapiens. In papers published Tuesday in eLife , the team—led by University of the Witwatersrand Wits paleoanthropologist Lee Berger —provides an age range for the remains first reported in between , and , years old.
The team also describes a second chamber within Rising Star that contains yet-undated H. If these dates hold, it could mean that while our own species was evolving from other, large-brained ancestors, a little-brained shadow lineage was lingering on from a much earlier period, perhaps two million years ago or more. When Homo naledi made its public debut in , several key details about the species still lurked in the shadows. How was H. And as National Geographic reported at the time , the initial announcement frustrated scientists because of what it was missing.

New fossils found in the Rising Cave system show Homo naledi lived alongside Homo sapiens. Advanced dating techniques suggest Homo naledi was much younger than thought and may have lived.
The claims surrounding this discovery have been extolled, criticized, and debated by both evolutionists and creationists. In fact, a science news piece in The Guardian highlighted the raging controversy among secular academics over H. Since the first journal publication describing H. As a result, we can now step back and take a fresh look at all the data and conclude that yet another false ape-man story has been perpetrated upon the public to prop up a failed paradigm of human evolution.
The story told by Berger in his book Almost Human reveals that a former student mysteriously showed up and convinced him to support an effort to explore caves in the area of South Africa where he was working. Fortuitously for Berger, the amateur explorers were able to penetrate the nearly inaccessible lower reaches of the Rising Star cave system and find a remote chamber littered with fossils. As the Rising Star cave system progresses downward, two extremely narrow passages connect the two lowest chambers Figure 1.
This mysterious human species lived alongside our ancestors, newly dated fossils suggest
In , a deep, at some points very narrow cave system called Rising Star in South Africa produced bones that would be identified as a new addition to the Homo genus, named Homo naledi. The over 1, bones found, belonging to at least 15 individuals of varying ages, shared many traits with ourselves, such as the structure of their hands, wrists and feet, while also having many stark differences, including a much smaller brain that is closer to the Homo habilis Hendry This mix of primitive and more modern features is curious, by not that surprising by itself, considering how complex the family tree is and how different members of the genus evolved in different ways.
The more surprising aspect of Homo naledi discovery is the age and location of the bones.

They were identified as a new human species with a surprising combination of features. Human evolution expert Prof Chris Stringer outlines some of the mysteries and contradictions presented by Homo naledi , and the fascinating possibilities it raises. Since this article was published, another new human relative has been described: Homo luzonensis.
Read the April news. The discovery of hundreds of Homo naledi fossils was the largest such find ever made on the African continent. The fossils display a unique mix of modern and archaic traits and are shaking up our understanding of the origins and diversity of our human lineage. Homo naledi highlights, once again, that we can’t think of human evolution in terms of ape-like ancestors gradually evolving more modern features in a linear fashion.
Instead, multiple human species evolved in parallel and coexisted, sometimes side-by-side.
Ancient human cousin found in South Africa is surprisingly young
October, , updated July an artist’s reconstruction of Homo Naledi But if you understand evolution, Homo naledi’s mix of traits is not at all surprising. There are plans to use radiocarbon dating on the fossils themselves, but since.
Furthermore, it raises significant questions regarding the pattern of human evolution more generally. Initially, the researchers who discovered and analyzed the skeletal remains of at least 15 individuals of this previously unknown species, which were found deep in a cave located roughly 50 km 30 miles northwest of Johannesburg, South Africa, thought that it was a very early member of the genus Homo. Based on evolutionarily primitive characteristics, including a small brain, but also some more progressive features, such as long leg bones, the scientists thought that the fossils could date to as much as 2.
This would place H. However, the lack of an independent dating method was problematic. Another discordant note was the condition of the bones, which were barely fossilized. Remains of individuals who died over 2 million years ago would be expected to have undergone a high degree of fossilization i. Now, one of three articles on H. The assays were run separately by several independent laboratories, thus supporting the validity of the results.
This finding indicates that primitive members of the genus Homo continued to exist alongside more advanced forms for hundreds of thousands of years, contemporaneous with not only Homo erectus , but even Neanderthals and, possibly, early Homo sapiens our own species. Along with the late persistence of another primitive species of Homo , H. This is contrary to the predominant pattern of evolution in which organisms tend to differentiate physically in order to adapt to particular ecological niches as they spread geographically.
Increasingly, however, the discovery of these and other human variants e.
