Between about 700,000 years in the past and 60,000 years in the past, a diminutive early human walked the island of Flores, in what’s now Indonesia. Homo floresiensis, nicknamed the “hobbit” as a result of it stood solely about 3 toes, 6 inches (106 centimeters) tall, was a small-brained, large-footed toolmaker, and nobody is aware of the place it developed from.
Now, one anthropologist is arguing that nobody actually is aware of that H. floresiensis went extinct — and that it could survive into the fashionable day. In a brand new e-book, Gregory Forth, an anthropologist retired from the University of Alberta, argues that reviews of an “ape-man” on Flores may very well be sightings of the traditional human ancestor, nonetheless kicking right now.
“We simply don’t know when this species became extinct or indeed dare I say — I did dare say — we don’t even know if it is extinct,” Forth instructed Live Science. “So there is some possibility that it is still alive.”
Needless to say, it is a dramatic declare, and consultants who examine H. floresiensis are skeptical.
“Flores is an island that has about the same area of Connecticut and has two million people living on it today,” stated John Hawks, a paleoanthropologist on the University of Wisconsin, Madison. The inhabitants is unfold out throughout the island, he added.

“Realistically, the idea that there’s a large primate that is unobserved on this island and surviving in a population that can sustain itself is pretty close to zero,” Hawks instructed Live Science.
An extended-lost relative
Forth sees it in a different way. He has been doing anthropological fieldwork on the island since 1984, and since that point has heard native tales of small, furry, humanoid creatures dwelling within the forest. He wrote about these tales in his analysis till 2003, when H. floresiensis was found. It was then, he instructed Live Science, that he made the connection.
“I heard about these similarly small humanlike creatures in a region called Lio, which were said to still be alive, and people were giving accounts of what they looked like,” Forth stated. In one excerpt from his new e-book, “Between Ape and Human: An Anthropologist on the Trail of a Hidden Hominoid,” (Pegasus Books, 2022), Forth describes an interview with a person who says he disposed of the corpse of a creature that would not have been a monkey however that was additionally not human, with straight light-colored hair on its physique, a well-formed nostril, and a stub of a tail. Over the years, Forth collected 30 eyewitness accounts of comparable creatures that, he stated, match the outline of H. floresiensis.
Of course, there are various eyewitness accounts of cryptic creatures world wide, resembling Sasquatch within the Pacific Northwest and British Columbia, stated Mark Collard, an evolutionary anthropologist based mostly at Simon Fraser University in Canada. Humans are adept at telling and believing tales, Collard instructed Live Science, and people tales can simply grow to be central to folks’s beliefs.
The tales of those “ape-men” on Flores are completely different from these of Bigfoot within the Pacific Northwest, Forth argued, as a result of there have by no means been non-human apes in North America. But in Flores, he stated, H. floresiensis indubitably did exist.
But how lengthy did they exist? H. floresiensis bones had been first present in Liang Bua cave on Flores in 2003. The youngest proof of the hobbits utilizing the cave dates again to 50,000 years in the past, stated Elizabeth Veatch, a zooarchaeologist at Emory University who research the species. Modern people do not seem on Flores till 47,000 years in the past, Veatch instructed Live Science, and there’s no proof that the 2 species overlapped at Liang Bua cave. In reality, H. floresiensis wasn’t utilizing the location a lot after 60,000 years in the past, she stated.
“Based on faunal evidence, there was likely an environmental change that occurred around 60,000 years ago that altered the landscape around Liang Bua which caused Homo floresiensis to migrate elsewhere on the island to forage in more suitable habitats,” Veatch stated.
In 2014, archaeologists found one other website on Flores, Mata Menge, with a fossil mandible and tooth from a hominin relationship again to about 700,000 years in the past. These bones are regarded as from a far older inhabitants of H. floresiensis. Stone instruments had been additionally discovered on the website.
These findings recommend that H. floresiensis had a protracted historical past on Flores (the species has not been discovered on every other island). But anthropologists and archaeologists have seen no indication that the hobbit lived alongside trendy people.
It is feasible that they did, for a time, Thompson stated. And if that’s the case, maybe the tales within the Lio area of Flores are a really deep cultural reminiscence. In Australia, Indigenous folks have tales that clearly correspond to actual occasions that occurred hundreds of years prior, together with a dramatic meteor strike. Something related could be taking place on Flores, Thompson stated.
“What we might have is a situation where [H. floresiensis] potentially persisted in mythology for a really long time,” she instructed Live Science.
But Thompson, too, was skeptical {that a} 3-foot-tall primate may go largely undetected on Flores till the fashionable day.
“We do turn up species that we think are extinct in science, it happens,” she stated, “But it’s small things. It’s not something that would be so noticeable.”
Collard agreed. “I just think we have to be very cautious with oral history,” he stated. “I think it has value, but it has to be approached skeptically.”
Mysterious ancestor
That’s to not say that H. floresiensis is not mysterious. The two websites containing bones and instruments from the primate date tons of of hundreds of years aside from one another, leaving an enormous hole in historical past. Researchers do know that hobbit used cobbles to make sharp stone flakes, knifelike instruments that would have been used to chop crops or meat or carve different instruments out of wooden, Hawks stated. It’s unknown whether or not H. floresiensis used fireplace or hunted massive prey.
Perhaps the most important query about H. floresiensis is the place the species got here from. Anatomically, the “hobbit” has tooth that look very similar to these of different Homo species resembling Homo erectus and Homo sapiens. H. floresiensis’ presence in Indonesia some 700,000 to 800,000 years in the past predates H. sapiens’ arrival by an enormous margin.
H. erectus, although, left Africa 1.8 million years in the past, and popped up on what’s right now the island of Java earlier than H. floresiensis within the fossil file. This raises the chance that the hobbit descended from H. erectus and maybe that it developed a small physique measurement because of island dwelling, a phenomenon referred to as island dwarfism.
But there are issues with that speculation. For one, Thompson instructed Live Science, H. erectus survived on different islands in Southeast Asia at its typical measurement till about 115,000 years in the past, and it will be odd for island dwarfism to happen solely on Flores and nowhere else over tons of of hundreds of years. And H. floresiensis has many anatomical options, resembling its shoulders and wrists, that look much less like its Homo cousins and extra like earlier human ancestors resembling Australopithecus.
“The anatomy doesn’t make it clear,” Hawks stated.
The anatomical proof means that H. floresiensis may have been the descendent of a human ancestor that left Africa earlier than H. erectus, Collard stated. If so, scientists have not but discovered archaeological proof for who that ancestor may need been or once they left.
Whatever the story of the journey, it will need to have been unbelievable. Tiny H. floresiensis or its ancestors in some way made it throughout continents and tough open water to land on the island of Flores. (There was all the time open water there, Collard stated, at the same time as sea ranges rose and fell over tons of of hundreds of years.) Evidence of different early hominins, such because the Philippines’ Homo luzonensis, found in 2019 on the island of Luzon, means that human ancestors had been doing way over anthropologists and archaeologists ever believed attainable.
“Was it an accidental rafting situation? Was it a deliberate rafting situation?” Collard stated. “It seems unlikely, but were they able to use boats?”
Overlapping populations?
What researchers in human origins are actually studying is that the interactions between early populations of Homo species had been terribly advanced. It’s now widespread information that Homo sapiens and Neanderthals interbred, and that Neanderthal DNA persists in trendy people. Humans in Oceania and East Asia additionally interbred with one other human ancestor, Denisovans, about which little is thought. Remarkably, Hawks stated, Denisovan genes persist in east Indonesian populations, suggesting that these human kin had been additionally dwelling on these islands. No fossil file has been discovered of Denisovans in jap Indonesia to this point, nevertheless.
The oldest cave artwork on file additionally comes from Indonesia, within the type of a crimson pig painted on the island of Sulawesi 45,500 years in the past.This artwork could have been made by Homo sapiens.
There is not any proof that people and H. floresiensis ever interbred. Scientists have not discovered any unknown genes within the trendy Indonesian genome that would hail again to the little hominin. The timing of the fossils which have been discovered recommend that the hobbit may have been dwelling fortunately on Flores till trendy people confirmed up and wiped it out, inadvertently or not, Hawks stated.
“It’s very plausible that modern humans are responsible for its extinction,” he stated.
Or maybe there are newer H. floresiensis fossils ready to be discovered that can show that the 2 Homo species overlapped. The final decade has been a golden age for Indonesian archaeology and worldwide collaborations between native scientists and the remainder of the world, Hawks stated. It’s virtually sure that extra discoveries are to come back.
“The fact that we only have a handful of sites that represent almost a million years of habitation of some of these places tells us that there’s a whole lot that we haven’t found,” Hawks stated.
