Would we still see ourselves as ‘human’ if other hominin species hadn’t gone extinct?

Would we still see ourselves as ‘human’ if other hominin species hadn’t gone extinct?

Would we see Neanderthals (right) as human if they were around today? wikipedia, CC BY-SA Nicholas R. Longrich, University of Bath READER QUESTION: We now know from evolutionary science that humanity has existed in some form or another for around 2 million years or more. Homo sapiens are comparatively new on the block. There were also many other human species, some which we interbred with. The question is then inevitable – when can we claim personhood in the long story…

Evidence of northernmost Stone Age hunters found above the Arctic Circle

Evidence of northernmost Stone Age hunters found above the Arctic Circle

Live Science reports: Ancient cut marks on mammoth bones unearthed on a remote island in the frozen extremes of Siberia are the northernmost evidence of Paleolithic humans ever found, according to archaeologists. The bones from the woolly mammoth skeleton, dated to about 26,000 years ago, were excavated this summer by a Russian expedition to Kotelny Island, in the far northeast of Siberia — 615 miles (990 kilometers) north of the Arctic Circle. The team pieced together more than two-thirds of…

Gibraltar cave chamber discovery could shed light on Neanderthals’ culture

Gibraltar cave chamber discovery could shed light on Neanderthals’ culture

The Guardian reports: Researchers excavating a cave network on the Rock of Gibraltar have discovered a new chamber, sealed off from the world for at least 40,000 years, that could shed light on the culture and customs of the Neanderthals who occupied the area for a thousand centuries. In 2012, experts began examining Vanguard Cave, part of the Gorham’s Cave complex, to determine its true dimensions and to see whether it contained passages and chambers that had been plugged by…

23,000-year-old footprints suggest people reached the Americas early

23,000-year-old footprints suggest people reached the Americas early

Ars Technica reports: Footprints left behind in layers of clay and silt at New Mexico’s White Sands National Park may be between 23,000 and 21,000 years old. That’s based on radiocarbon dating of the remains of grass seeds buried in the layers of sediment above and below the tracks. If the dates are correct, the tracks are evidence that people walked beside the now-dry Lake Otero during the height of the last ice age, when kilometers of ice covered the…

DNA offers surprises on how Polynesia was settled

DNA offers surprises on how Polynesia was settled

Science reports: The peopling of Polynesia was a stunning achievement: Beginning around 800 C.E., audacious Polynesian navigators in double-hulled sailing canoes used the stars and their knowledge of the waves to discover specks of land separated by thousands of kilometers of open ocean. Within just a few centuries, they had populated most of the Pacific Ocean’s far-flung islands. Now, researchers have used modern DNA samples to trace the exploration in detail, working out what order the islands were settled in…

Fossils and ancient DNA paint a vibrant picture of human origins

Fossils and ancient DNA paint a vibrant picture of human origins

Erin Wayman writes: In The Descent of Man, published in 1871, Charles Darwin hypothesized that our ancestors came from Africa. He pointed out that among all animals, the African apes — gorillas and chimpanzees — were the most similar to humans. But he had little fossil evidence. The few known human fossils had been found in Europe, and those that trickled in over the next 50 years came from Europe and from Asia. Had Darwin picked the wrong continent? Finally,…

Inflammatory responses to pathogens changed dramatically during the Neolithic period

Inflammatory responses to pathogens changed dramatically during the Neolithic period

Science reports: When early farmers of the Vinca culture first sowed barley and wheat 7700 years ago in the rich soil of the Danube River and its tributaries, they changed more than their diet: They introduced a new way of life to the region. They crowded together in mud huts, living cheek by rump with aurochs, cows, pigs, and goats—and their poop—in settlements that eventually swelled to thousands of people. Togetherness brought a surge in diseases such as influenza, tuberculosis,…

Research reveals humans ventured out of Africa repeatedly as early as 400,000 years ago to visit Arabia

Research reveals humans ventured out of Africa repeatedly as early as 400,000 years ago to visit Arabia

Eleanor Scerri, Author provided By Julien Louys, Griffith University; Gilbert Price, The University of Queensland; Huw Groucutt, Max Planck Institute for the Science of Human History, and Michael Petraglia, Max Planck Institute for the Science of Human History If you stood in the middle of the Nefud Desert in central Arabia today, you’d be confronted on all sides by enormous sand dunes, some rising more than 100 meters from the desert floor. The few scraggly bushes make poor browse for…

For most of human history, equality was the norm. What happened?

For most of human history, equality was the norm. What happened?

Kim Sterelny writes: Most of us live in social worlds that are profoundly unequal, where small elites have vastly more power and wealth than everyone else. Very few of the have-nots find this congenial. As experimental economists have shown, we tend to enter social situations prepared to take a chance and cooperate in collective activities. But if others take more than their share, we resent being played for a sucker. We live in unequal worlds, and few of us are…

Humans started growing cannabis 12,000 years ago

Humans started growing cannabis 12,000 years ago

ZME Science reports: A new study traced back the origin of cannabis agriculture to nearly 12,000 years ago in East Asia. During this time cannabis was likely a multipurpose crop — it was only 4,000 years ago that farmers started growing different strains for either fiber or drug production. Although it’s largely understudied due to legal reasons, cannabis is one of the first plants to be domesticated by humans. Archaeological studies have found traces of cannabis in various different cultures…

As little as 1.5% of our genome is ‘uniquely human’

As little as 1.5% of our genome is ‘uniquely human’

Live Science reports: Less than 10% of your genome is unique to modern humans, with the rest being shared with ancient human relatives such as Neanderthals, according to a new study. The study researchers also found that the portion of DNA that’s unique to modern humans is enriched for genes involved with brain development and brain function. This finding suggests that genes for brain development and function are what really set us apart, genetically, from our ancestors. However, it’s unclear…

51,000-year-old bone carving suggests Neanderthals were true artists

51,000-year-old bone carving suggests Neanderthals were true artists

Gizmondo reports: Patterns deliberately etched onto a bone belonging to a giant deer are signs that Neanderthals possessed the capacity for symbolic thought. Neanderthals decorated themselves with feathers, drew cave paintings, and created jewelry from eagle talons, so it comes as little surprise to learn that Neanderthals also engraved patterns onto bone. The discovery of this 51,000-year-old bone carving, as described in Nature Ecology & Evolution, is more evidence of sophisticated behavior among Neanderthals. “Evidence of artistic decorations would suggest…

Discovery of ‘Dragon Man’ skull in China may add species to human family tree

Discovery of ‘Dragon Man’ skull in China may add species to human family tree

The New York Times reports: Scientists on Friday announced that a massive fossilized skull that is at least 140,000 years old is a new species of ancient human, a finding that could potentially change prevailing views of how — and even where — our species, Homo sapiens, evolved. The skull belonged to a mature male who had a huge brain, massive brow ridges, deep set eyes and a bulbous nose. It had remained hidden in an abandoned well for 85…

It looks like the real paleo diet often included lots of grains

Nature reports: On a clear day, the view from the ruins of Göbekli Tepe stretches across southern Turkey all the way to the Syrian border some 50 kilometres away. At 11,600 years old, this mountaintop archaeological site has been described as the world’s oldest temple — so ancient, in fact, that its T-shaped pillars and circular enclosures pre-date pottery in the Middle East. The people who built these monumental structures were living just before a major transition in human history:…

How did Neanderthals and other ancient humans learn to count?

How did Neanderthals and other ancient humans learn to count?

Nature reports: Some 60,000 years ago, in what is now western France, a Neanderthal picked up a chunk of hyena femur and a stone tool and began to work. When the task was complete, the bone bore nine notches that were strikingly similar and approximately parallel, as if they were meant to signify something. Francesco d’Errico, an archaeologist at the University of Bordeaux, France, has an idea about the marks. He has examined many ancient carved artefacts during his career,…
