Prehistoric humans invented stone tools multiple times, study finds

Comments 0 Comment

The Independent reports: Prehistoric humans invented tools on multiple occasions, according to researchers who have found a collection of 327 stone weapons carved more than 2.58 million years ago. This is the first evidence of ancient hominids sharpening stones to create specific tools, according to new research led by Arizona State University and George Washington University. The collection of “Oldowan” tools – which are created by chipping off bits of stone – were found in the Afar region of north-eastern…

The dancing species: How moving together in time helped make us human

By Kimerer LaMothe Dancing is a human universal, but why? It is present in human cultures old and new; central to those with the longest continuous histories; evident in the earliest visual art on rock walls from France to South Africa to the Americas, and enfolded in the DNA of every infant who invents movements in joyful response to rhythm and song, long before she can walk, talk or think of herself as an ‘I’. Dancing remains a vital, generative…

Stucco frieze from Placeres, Campeche, Mexico, Early Classic period, c. 250-600 AD. Wolfgang Sauber/Wikimedia, CC BY-SA By Kenneth Seligson, California State University, Dominguez Hills Carbon dioxide concentrations in Earth’s atmosphere have reached 415 parts per million – a level that last occurred more than three million years ago, long before the evolution of humans. This news adds to growing concern that climate change will likely wreak serious damage on our planet in the coming decades. While Earth has not been…

Hippos at Gorongosa National Park. Brett Kuxhausen, Author provided, Author provided By René Bobe, University of Oxford and Susana Carvalho, University of Oxford What triggered the decline and eventual extinction of many megaherbivores, the giant plant-eating mammals that roamed the Earth millions of years ago, has long been a mystery. These animals, which weighed 1,000kg or more and included the ancient relatives of modern elephants, rhinos, hippos and giraffes, reached a peak of diversity in Africa some 4.5m years ago…

Why speech is a human innovation

Why speech is a human innovation

By Tom Siegfried Except for various cartoon characters, the Geico Gecko and Mr. Ed, animals can’t speak. Yet they have a lot to say to scientists trying to figure out the origins of human language. Speaking isn’t the only avenue for language. After all, linguistic messaging can be transmitted by hand signals. Or handwriting. Or texting. But speech is the original and most basic mode of human communication. So understanding its origins ought to generate deeper comprehension of language more…

A jawbone shows Denisovans lived on the Tibetan Plateau long before humans

A jawbone shows Denisovans lived on the Tibetan Plateau long before humans

Comments 0 Comment

Science News reports: Denisovans reached what’s now called “the roof of the world” at least 160,000 years ago. Found in a Tibetan Plateau cave, a partial lower jawbone represents a Denisovan who is the oldest known hominid to reach the region’s cloud-scraping heights, researchers report online May 1 in Nature. The fossil suggests that these perplexing, extinct members of the human lineage weathered the plateau’s frigid, thin air long before humans did. Many researchers have assumed that, as far as…

A 3D recreation of a recently discovered Neanderthal tooth. Joshua Lindal, Author provided By Mirjana Roksandic, University of Winnipeg and Joshua Allan Lindal, University of Winnipeg In 2015, our Serbian-Canadian archaeological research team was working at a cave site named Pešturina, in Eastern Serbia, where we had found thousands of stone tools and animal bones. One day, an excited Serbian undergrad brought us a fossil they had uncovered: a small molar tooth, which we immediately recognized as human. A single…

How culture works with evolution to produce human cognition

How culture works with evolution to produce human cognition

Comments 0 Comment

Cecilia Heyes writes: The conventional view, inside and outside academia, is that children are ‘wired’ to imitate. We are ‘Homo imitans’, animals born with a burning desire to copy the actions of others. Imitation is ‘in our genes’. Birds build nests, cats miaow, pigs are greedy, while humans possess an instinct to imitate. The idea that humans have cognitive instincts is a cornerstone of evolutionary psychology, pioneered by Leda Cosmides, John Tooby and Steven Pinker in the 1990s. ‘[O]ur modern…

Non-modern humans were more complex — and artistic — than we thought

Marc Kissel writes: Not surprisingly, claims of symbolic artifacts made by non-modern humans have been met with intense scrutiny. Part of this is due to the fragmentary nature of the early archaeological record, but there is also a deeply held assumption that only Homo sapiens could produce such artifacts. Rather than fetishizing the ability to make symbols, we should instead concentrate on how our ancestors found novel and innovate ways to create and share meaning. My colleague, Agustín Fuentes, and…

  Science magazine reports: A strange new species may have joined the human family. Human fossils found in a cave on Luzon, the largest island in the Philippines, include tiny molars suggesting their owners were small; curved finger and toe bones hint that they climbed trees. Homo luzonensis, as the species has been christened, lived some 50,000 to 80,000 years ago, when the world hosted multiple archaic humans, including Neanderthals and Denisovans, and when H. sapiens may have been making…

Pro-social religions didn’t kick-start complex social systems

Scientific American reports: About 12,000 years ago human societies went big; tribes and villages grew into vast cities, kingdoms and empires within just a few millennia. For such large and complex societies to take root, people needed to maintain social cohesion and cooperation, even among complete strangers. What enabled this, many researchers have argued, was religion. Such a religion, the idea goes, would work particularly well if it established standards of morality and behavior—and enforced them with the threat of…

The rise of farming altered our bite and changed how people talk

The rise of farming altered our bite and changed how people talk

Comments 0 Comment

Science News reports: Humankind’s gift of gab is not set in stone, and farming could help to explain why. Over the last 6,000 years or so, farming societies increasingly have substituted processed dairy and grain products for tougher-to-chew game meat and wild plants common in hunter-gatherer diets. Switching to those diets of softer, processed foods altered people’s jaw structure over time, rendering certain sounds like “f” and “v” easier to utter, and changing languages worldwide, scientists contend. People who regularly…

Rebecca Wragg Sykes writes: Who were the Neanderthals? Even for archaeologists working at the trowel’s edge of contemporary science, it can be hard to see Neanderthals as anything more than intriguing abstractions, mixed up with the likes of mammoths, woolly rhinos and sabre-toothed cats. But they were certainly here: squinting against sunrises, sucking lungfuls of air, leaving footprints behind in the mud, sand and snow. Crouching to dig in a cave or rock-shelter, I’ve often wondered what it would be…

Sy Montgomery writes: The two old friends hadn’t seen each other lately. Now one of them was on her deathbed, crippled with arthritis, refusing food and drink, dying of old age. Her friend had come to say goodbye. At first she didn’t seem to notice him. But when she realized he was there, her reaction was unmistakable: Her face broke into an ecstatic grin. She cried out in delight. She reached for her visitor’s head and stroked his hair. As…

By Leah Shaffer In January 2016, Cathryn Townsend set out to live among “the loveless people.” So named by anthropologist Colin Turnbull, the Ik are a tribe of some 11,600 hunter-gatherers and subsistence farmers living in an arid and harsh mountainous region of Uganda. Turnbull studied the Ik in the 1960s and famously characterized them as “inhospitable and generally mean” in his book The Mountain People. He documented how young children were abandoned to starve and how people would snatch…

JuliusKielaitis / shutterstock By Mark Maslin, UCL Human society rewards individuals who can handle complex social interactions and control large groups of people. Extreme examples of this power are comedians who can fill stadiums entertaining 70,000 people, or politicians who, through their rhetoric and charm, convince millions of us to vote for them so they can run our lives. Intelligence, humour, and charisma are used to co-opt a greater share of resources for themselves and their family. In fact, many…
