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 , an 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.

This conclusion seems oddly convenient, as a date range matching their age assumptions would have almost certainly been reported. Why haven't they tried basic carbon dating? Instead, it appears they assume the bones are simply too old to contain measurable amounts of carbon In contrast, detectable carbon would demonstrate a youthful age for the bones-but that would place Homo naledi alongside species of modern humans.

The researchers could also have used electron spin resonance ESR dating that other evolutionists use for tooth enamel in similar settings.

But no test was conducted. It seems they don't really want an absolute age for these bones. Why wouldn't a team of high-profile, cutting edge scientists use every dating and testing method at their disposal to help clarify exactly what these specimens are and therefore what they truly represent?

Instead, it appears the researchers are telling us what they think the fossils are.

Remarkable, rather homo naledi carbon dating answer

If the scientists determined an age in the thousands of years or even the ten-thousands of years ranges, it would keep naledi out of the larger evolutionary story and glorious spotlight of public attention-and especially funding, the holy grail of many research scientists. Worse, an age of thousands of years would clearly expose these fossils merely as man-made mosaics of different species, and not an evolutionary transition.

In other words, it would nullify their find.

In contrast, detectable carbon would demonstrate a youthful age for the bones-but that would place Homo naledi alongside species of modern humans.

May 09,   Recent dating of the geology of Rising Star places Homo naledi in a period roughly , years ago, when multiple other hominin species were alive-including archaic forms of Homo. Indeed, H. naledi has been described as having features "similar to early Homo species including Homo erectus, Homo habilis and Homo rudolfensis" 9. There are increasing numbers of evolutionary paleoanthropologists who today argue that these are arbitrary species designations of variations of . Homo naledi, (Latin and Sesotho mix: "star man") extinct species of human, initially thought to have evolved about the same time as the emergence of the genus Homo, some million to million years ago, during the Pliocene ( million to about million years ago) and Pleistocene (about million years ago to 11, years ago) epochs.

In the s, the names "Empire", "Westminster", and "Rising Star" were used interchangeably. The species name, naledi seSotho for "star"and the "Dinaledi Chamber" incorporating the Sotho word for "stars" [4] were so named by members of the Rising Star Expedition in reference to the species and chamber's location in Rising Star Cave. A portion of the cave, used by the excavation team en route to the Dinaledi Chamber, is called "Superman's Crawl" because most people can fit through only by holding one arm tightly against the body and extending the other above the head, in the manner of Superman in flight.

The Superman Crawl opens into the "Dragon's Back Chamber," which includes an approximately 15 m 49 foot exposed climb up a ridge of a sharp-edged dolomite block that fell from the roof sometime in the distant past.

This block is the so-called Dragon's Back, so named because the climbing route appears to progress from the tail to the head along the spiked spine of a mythical beast. Geologists think the cave in which the fossils were discovered is no older than three million years.

The arrangement of bones, as well as several survey pegssuggested "someone had already been there" as recently as a few decades earlier. Berger organized an expedition to excavate the fossils, which started on 7 November More than 1, fossil elements were recovered and catalogued in November[16] representing at least a dozen individuals. The layered distribution of the bones [in clay-rich sediments] suggests that they had been deposited over a long period of time, perhaps centuries.

The bones of both old and young individuals, as well as infants, were found. The 15 partial skeletons, which were found in a small underground chamber, invite speculation on the circumstances of their location.

Paleoanthropologist John D. Hawksfrom the University of Wisconsin-Madison, who is a member of the team, has stated that the scientific facts are that all the bones recovered are hominin, except for those of one owl; there are no signs of predation, and there is no predator that accumulates only hominins this way; the bones did not accumulate there all at once.

The age of the original Homo naledi remains from the Dinaledi Chamber has been revealed to be startlingly young in age. Homo naledi, which was first announced in Septemberwas alive sometime between and thousand years ago. This places this population of primitive small-brained hominins at a time and place that it is likely they lived alongside Homo sapiens. A collaborative workshop involving 54 local and international scientists took place in May at the University of the Witwatersrand, [2] [19] [32] On 10 Septemberthe fossils were publicly unveiled and given the name Homo naledi.

The fossils of the Dinaledi chamber have been dated to betweenan years ago, long after much larger-brained and more modern-looking hominins had appeared. The Rising Star cave system lies in the Bloubank River valley, 2.
