Two bonobos adopted infants outside their group, marking a first for great apes

Two bonobos adopted infants outside their group, marking a first for great apes

Science News reports: Attentive parenting appears across the animal world, but adoption is rarer, especially when youngsters taken in aren’t kin. Now researchers have witnessed bonobos adopting infants from outside of their own communities. Two females, each from a different bonobo group, in the Luo Scientific Reserve in Congo took charge of orphans — grooming them, carrying them and providing food for at least a year. Two instances of adopted outsiders are known in other nonhuman primates, but this is…

How scientific taxonomy constructed the myth of race

How scientific taxonomy constructed the myth of race

By Brittany Kenyon-Flatt, SAPIENS As a graduate assistant in biological anthropology at the University at Buffalo, I was tasked with curating the primate skeletal collection. The collection of skeletons—taken from cadavers studied during a primate anatomy class—had been neglected for a few years. Most of the specimens had lost their labels. So, when I began re-cataloguing the collection in 2016, I ran into trouble. I knew that the skeletons were from three different species of macaques, but I didn’t know…

Neanderthals helped create early human art, researcher says

Neanderthals helped create early human art, researcher says

The Guardian reports: When Neanderthals, Denisovans and homo sapiens met one another 50,000 years ago, these archaic and modern humans not only interbred during the thousands of years in which they overlapped, but they exchanged ideas that led to a surge in creativity, according to a leading academic. Tom Higham, a professor of archaeological science at the University of Oxford, argues that their exchange explains “a proliferation of objects in the archaeological record”, such as perforated teeth and shell pendants,…

What fueled humans’ big brains? Controversial paper proposes new hypothesis

What fueled humans’ big brains? Controversial paper proposes new hypothesis

Stephanie Pappas writes: Over the course of the Pleistocene epoch, between 2.6 million years ago and 11,700 years ago, the brains of humans and their relatives grew. Now, scientists from Tel Aviv University have a new hypothesis as to why: As the largest animals on the landscape disappeared, the scientists propose, human brains had to grow to enable the hunting of smaller, swifter prey. This hypothesis argues that early humans specialized in taking down the largest animals, such as elephants,…

Evolution: lab-grown ‘mini brains’ suggest one mutation might have rewired the human mind

Evolution: lab-grown ‘mini brains’ suggest one mutation might have rewired the human mind

The brains of humans are subtly different from those of Neanderthals. Petr Student/Shutterstock By Itzia Ferrer, Lund University and Per Brattås, Lund University How we humans became what we are today is a question that scientists have been trying to answer for a long time. How did we evolve such advanced cognitive abilities, giving rise to complex language, poetry and rocket science? In what way is the modern human brain different from those of our closest evolutionary relatives, such as…

The origin of modern humans cannot be traced to any one single point of time or place

The origin of modern humans cannot be traced to any one single point of time or place

Science Alert reports: Homo sapiens today look very different from our evolutionary origins, the microbes wriggling about in the primordial mud. But our emergence as a distinct species cannot, based on the current evidence, be conclusively traced to a single location at any single point in time. In fact, according to a team of scientists, who have conducted a thorough review of our current understanding of human ancestry, there may never even have been such a time. Instead, the earliest…

Not all early human societies were small scale egalitarian bands

Not all early human societies were small scale egalitarian bands

Manvir Singh writes: The Harvard Kalahari Project propelled the !Kung into anthropological stardom. By 1976, researchers on the team had published more than 100 academic articles, on topics as varied as infant care, trance healing, and blood pressure. The research sparked more interest, which drew in more anthropologists, which produced more research. In a video for the Annual Review of Anthropology in 2012, DeVore speculated that there was no culture ‘outside the West that has as much fine-grained data on…

In ice age Siberia, a meeting of carnivores may have given us dogs

In ice age Siberia, a meeting of carnivores may have given us dogs

The New York Times reports: Twenty-three thousand years ago, in the cold of the last ice age, some humans found a place where the climate was marginally better: Siberia. While many people associate the region that is now in Russia with forbidding cold today, climate data as well as archaeological and DNA evidence show that this was where horses, mammoths and other prey animals found enough to eat, which attracted humans and other carnivores. Hemmed in by worse conditions, the…

What do we know about the lives of Neanderthal women?

What do we know about the lives of Neanderthal women?

Rebecca Wragg Sykes writes: The first Neanderthal face to emerge from time’s sarcophagus was a woman’s. As the social and liberal revolutions of 1848 began convulsing Europe, quarry workers’ rough hands pulled her from the great Rock of Gibraltar. Calcite mantling her skull meant that, at first, she seemed more a hunk of stone than a once warm-blooded being, and obscured her decidedly odd anatomy – massive eyes, heavy brow ridges and a low, long cranium. While monarchies fell and…

What new science techniques tell us about ancient women warriors

What new science techniques tell us about ancient women warriors

Annalee Newitz writes: Though it’s remarkable that the United States finally is about to have a female vice president, let’s stop calling it an unprecedented achievement. As some recent archaeological studies suggest, women have been leaders, warriors and hunters for thousands of years. This new scholarship is challenging long-held beliefs about so-called natural gender roles in ancient history, inviting us to reconsider how we think about women’s work today. In November a group of anthropologists and other researchers published a…

Could Covid-19 have wiped out the Neandertals?

Could Covid-19 have wiped out the Neandertals?

John Hewitt writes: Everybody loves Neandertals, those big-brained brutes we supposedly outcompeted and ultimately replaced using our sharp tongues and quick, delicate minds. But did we really, though? Is it mathematically possible that we could yet be them, and they us? By the same token, could not the impossibly singular Mitochondrial Eve, her contemporary Y-chromosome Adam, and even the “Out of Africa” hypothesis simply be convenient fictions paleogeneticists tell each other at conferences to give their largely arbitrary haplotype designations…

How civilization broke our brains

How civilization broke our brains

Derek Thompson writes: Several months ago, I got into a long discussion with a colleague about the origins of the “Sunday scaries,” the flood of anxiety that many of us feel as the weekend is winding down and the workweek approaches. He said that the culprit was clear, and pointed to late-stage capitalism’s corrosive blend of performance stress and job insecurity. But capitalism also exists Monday through Saturday, so why should Sunday be so uniquely anxiety-inducing? The deeper cause, I…

Is anyone on Earth not an immigrant?

Is anyone on Earth not an immigrant?

Kelly Slivka writes: Human beings tend to be fascinated with their beginnings. Origin stories are found across cultures, religions, ethnicities and nationalities — and they are all deeply important. These stories tell people where they come from, how they fit in and how everyone fits together. One of these stories, of course, is the story of human genes, and it’s a story anyone with human DNA shares. As scientists find more ancient human DNA, sample more modern DNA and develop…

Homo erectus, not humans, may have invented bone tools at least 800,000 years ago

Science News reports: A type of bone tool generally thought to have been invented by Stone Age humans got its start among hominids that lived hundreds of thousands of years before Homo sapiens evolved, a new study concludes. A set of 52 previously excavated but little-studied animal bones from East Africa’s Olduvai Gorge includes the world’s oldest known barbed bone point, an implement probably crafted by now-extinct Homo erectus at least 800,000 years ago, researchers say. Made from a piece…

Turbulent environment set the stage for leaps in human evolution and technology 320,000 years ago

Drilling 139 meters down to volcanic rock provided scientists with a million-year environmental record. Human Origins Program, Smithsonian By Richard Potts, Smithsonian Institution People thrive all across the globe, at every temperature, altitude and landscape. How did human beings become so successful at adapting to whatever environment we wind up in? Human origins researchers like me are interested in how this quintessential human trait, adaptability, evolved. At a site in Kenya, my colleagues and I have been working on this…
