Scientists claim they’ve found the oldest human remains outside of Africa

All rights reserved. These fragmented fossils, which were found mere inches apart, could be the skulls from two hominin species separated by tens of thousands of years—a ,year-old Neanderthal left and a ,year-old early modern human. Along the rugged coastline of southern Greece, our ancient human relatives may have sojourned in what was once a balmy refuge from the encroaching glaciers of the mid-Pleistocene. While most vanished without a trace, skulls from two individuals were somehow swept into a deep crack in the ground, where the bones became cemented in a jumble of earth. Hundreds of thousands of years later, analyses of these remains hint at an unexpected identity: One skull fragment may have belonged to an early modern human that lived at least , years ago, making it the oldest human fossil yet found outside of Africa. If confirmed, the discovery would help clarify the earliest movements of our species as anatomically modern humans spread out of Africa. But not everyone is convinced by the strength of this new evidence.

All of these methods measure the amount of radioactive decay of chemical elements; the decay occurs in a consistent manner, like a clock, over long periods of time. Thermo-luminescence , Optically stimulated luminescence , and Electron spin resonance. All of these methods measure the amount of electrons that get absorbed and trapped inside a rock or tooth over time.

The result is the oldest well-dated evidence of Homo sapiens, pushing a date of , years based on radiometric dating of a human tooth. teeth, and leg and arm bones from at least five individuals, including a child.

The pacific rat kiore spread with voyaging humans; therefore, its earliest presence in New Zealand indicates initial human contact. Radiocarbon dating of kiore bones suggests they were introduced to New Zealand c. However, these radiocarbon ages are controversial because there is no supporting ecological and archaeological evidence for the presence of kiore or humans until c. An international team of researchers, led by Dr Janet Wilmshurst from Landcare Research, spent 4 years on a study which shows conclusively that the earliest evidence for human colonisation is about AD, and no earlier.

They based their results on new radiocarbon dating of Pacific rat bones and rat-gnawed seeds. Their results do not support previous radiocarbon dating of Pacific rat bones. Their study is the first time that the actual sites involved in the original study have been re-excavated and analyzed. Furthermore, the reliability of the bone dating has been questioned, with explanations for their anomalously old ages ranging from variations in laboratory pre treatments to bone contamination through either post-mortem processes or dietary- related offsets.

Dr Wilmshurst and her team researchers re-excavated and re-dated bones from nearly all of the previously investigated sites. All of their new radiocarbon dates on kiore bones are no older than AD. As the Pacific rat or kiore cannot swim very far, it can only have arrived in New Zealand with people on board their canoes, either as cargo or stowaways.

Therefore, the earliest evidence of the Pacific rat in New Zealand must indicate the arrival of people. The dating of the rat bones was also supported by the dating of over a hundred woody seeds, many of which had distinctive tell-tale rat bite marks, preserved in peat and swamp sites from the North and South Islands.

Humans, as we understand them, actually have a fairly ancient legacy on this planet. Anthropologists typically refer to any species in the genus Homo as human. The oldest reliably classified fossils belonging to the genus Homo date back to a little over 2 million years ago. They belong to H. For the oldest fossils of H.

There are two very different theories regarding the origins of modern Southeast Asians. The viewpoints about the origins of these peoples are entangled with the wider debate regarding the origins of all modern humans. The fossil record is poor for dates from about , years ago to about 25, years ago – a key time span for the a presumed arrival, or evolution, of modern humans in this region.

Human bones were found in a Bulgarian cave dating back 45, years; It is the earliest direct evidence ever found for modern humans in.

Follow our live coverage for the latest news on the coronavirus pandemic. The child was no more than three years old when it died, but its tiny skull provides the earliest ever glimpse into the lineage that gave rise to us. Palaeoarchaeologists say the toddler’s skull, which was unearthed in South Africa, belonged to the earliest group of humans known as Homo erectus. While this ancient species had a smaller brain than us, it walked upright and was the first to wander out of Africa to settle large parts of the world, right through to Asia.

Professor Herries said the skull, described today in the journal Science and estimated to be 2 million years old, is now the oldest known Homo erectus fossil in the world. The discovery of the toddler’s skull could help us understand more about our ancestors. Professor Herries and his team first unearthed a thin fragment in in the Drimolen cave system near Johannesburg. Over the next five years the team, which included researchers from a number of Australian universities, excavated more than fragile fragments.

It wasn’t until they started to put the pieces together like a puzzle that they realised the skull was too big to be a baboon.

Skull of a toddler is the oldest known fossil of the earliest human, Homo erectus

Anthropologists have discovered the remains of the earliest known human ancestor in Ethiopia, dating to between 5. The previous discovery of the 4. The fossil finds, reported in the July 12 issue of Nature, were made by National Science Foundation NSF -funded scientists over a four-year period in Ethiopia’s Middle Awash study area, about miles northeast of the capital, Addis Ababa. To the team of scientists, the discovery represents more evidence to confirm Darwin’s conclusion that the earliest humans, or hominids, arose in Africa.

Researchers have found the earliest example of our species (modern humans) outside Africa. A skull unearthed in Greece has been dated to.

Anthony Sinclair receives funding from The British Academy, and the Wainwright Fund at the University of Oxford for research on the the dispersal of early hominins. A ,year-old human skull could provide new evidence that our species left Africa much earlier than previously thought. A new study published in Nature of two fossils found in Greece in the s shows that one of them is the oldest Homo sapiens specimen ever found outside Africa by more than 50, years.

The human skull was one of two cranial fossils found in Apidima Cave, one of a series of cave sites along the southwestern coast of the Peloponnese in Greece. The first, known as Apidima 1, comprised half of the rear of a skull case. Apidima 2 was a largely complete skull with a clear face, but had been heavily distorted during the fossilisation process.

For decades, scientists have speculated about when exactly the bipedal apes known as Homo sapiens left Africa and moved out to conquer the world. For many years, the consensus view among archaeologists placed the exodus at 60, years ago—some , years after the hominins first appeared. But now, researchers in Israel have found a remarkably preserved jawbone they believe belongs to a Homo sapiens that was much, much older. But this new discovery goes one step further: if verified, it would require reevaluating the whole history of human evolution—and possibly pushing it back by several hundred thousand years.

All of their new radiocarbon dates on kiore bones are no older than AD. This is consistent with other evidence from the oldest dated archaeological sites,​.

The artifacts have been dated to as far back as 16, years ago, making them the oldest radiocarbon dated evidence of humans in North America, according to research published Thursday in the journal Science. Together with dozens of other archaeological sites stretched across the continent, it helps decipher the story of when, and how, humans first arrived.

Those people supposedly brought the technology to make Clovis-type blades and spear points with them , and then spread their shared culture across the continent. That’s the model currently taught in most history books. Other early sites challenged this theory, but none were this old, and the oldest were dated with a method considered less precise than radiocarbon dating.

Ancient humans may have moved by boat down the coast, and turned left up the Columbia, following the river to its tributaries and their eventual home at Cooper’s Ferry. Braje supports an alternative theory to the ice-free corridor: one where instead of traveling to the New World by land, ancient Americans came by sea. They traveled from Asia to North America by island-hopping and hugged the shore, following a coastal “kelp highway” full of sheltered bays and rich with food. The idea was once controversial, but in recent years it’s gained support.

Just like the ice-free corridor model is supported by a shared technology and shared culture found across a region, the kelp highway hypothesis also has a uniting technology: stemmed points.
