Research into the development of human language. By Matt Phillips Introduction Picture a human being before the dawn of language. They are returning to camp one afternoon. Walking along the beach, they stop to listen to the sounds of waves. Maybe they’ve never stopped like this before, or maybe it’s the tenth or the hundredth time,[…]
Our biggest evolutionary advantages are an ability to walk on two legs and our big brains. By Dr. Evan SimonsPostdoctoral Research Associate in AnthropologyUniversity at BuffaloState University of New York Introduction Everything that is alive today has evolved, including human beings. Our ancestors evolved many traits that helped them survive in their environments, and we still[…]
Bonobos may help explain how humans evolved the capacity to be nice – at least some of the time. Introduction It’s feeding time at Lola ya Bonobo, a sanctuary for bonobos in the Democratic Republic of the Congo. “Allez,” caretaker Bernard Nsangu shouts in French as he gets ready to distribute a morning snack. The[…]
The longest known trackway of ancient human fossil footprints, offering evidence of interactions between an adult and a child. Introduction Every parent knows the feeling. Your child is crying and wants to go home, you pick them up to comfort them and move faster, your arms tired with a long walk ahead—but you cannot stop[…]
Early Neanderthals likely benefited from an ingression of H. sapiens Y chromosomes some-time between 370,000 and 100,000 years ago. An international team led by Martin Petr and Janet Kelso of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, has succeeded in sequencing the Y chromosomes of two Denisovans and three Neanderthals. The surprising[…]
Scientists discovered a living microbial mat that uses arsenic instead of oxygen for photosynthesis and respiration. Introduction Billions of years ago, life on Earth was mostly just large slimy mats of microbes living in shallow water. Sometimes, these microbial communities made carbonate minerals that over many years cemented together to become layered limestone rocks called[…]
Examining the lifestyle of these early humans, their distinctive characteristics, and what they were like. By Lisa Hendry Introduction We know more facts about Neanderthals than any other extinct humans. Many thousands of their artefacts and fossils have been found, including several nearly complete skeletons. We also know about their genetic make-up, as several Neanderthal[…]
2.6-million-year-old tools from Olduvai Gorge in Tanzania. Introduction The appearance of simple stone tools, widely known as Oldowan tools or the Oldowan industry, marked the beginning of our technological revolution. To our knowledge, these artifacts appeared around 2.6 million years ago in the savannahs of Eastern Africa. Today, the Oldowan is still the earliest, universally acknowledged stone tool[…]
Larger brains lead to a broader social network. 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[…]
The footprints of over 20 different prehistoric people show possible evidence for sexual division of labor in this ancient community. Introduction When it comes to reconstructing how ancient creatures lived, palaeontologists like us are as much detectives as we are scientists. We’re used to partial evidence, dead ends and red herrings. It’s especially hard to[…]
Key human adaptations evolved in response to environmental instability. Climate Fluctuation Paleoanthropologists – scientists who study human evolution – have proposed a variety of ideas about how environmental conditions may have stimulated important developments in human origins. Diverse species have emerged over the course of human evolution, and a suite of adaptations have accumulated over[…]
The skull of Oculudentavis provides new clues into the transition from dinosaurs to birds and may be smallest of either ever found. Introduction In 2016, our colleague Xing Lida held up a small piece of polished, deeply yellow amber. As sunlight shone through the ancient resin, Lida saw the outline of a pristinely preserved, amazingly[…]
The taxon Dinosauria was formally named by the English palaeontologist Richard Owen in 1842. Introduction Dinosaurs are an extinct, diverse, largely terrestrial group of vertebrate animals of the Sauropsid orders Saurischia (lizard-hipped) and Ornithischia (bird-hipped) and were the dominant land reptiles for over 160 million years, during the Mesozoic era. Dinosaurs first appeared approximately 230[…]
The discovery of a new species related to dinosaurs, an iguana-sized reptile whose genus name, Antarctanax, means “Antarctic king.” Introduction Antarctica wasn’t always a frozen wasteland. About 250 million years ago, it was covered in forests and rivers, and the temperature rarely dipped below freezing. It was also home to diverse wildlife, including early relatives[…]
It is clear that a major extinction event occurred around Antarctica in the period 2–3 million years ago. Introduction Life has been on earth for about 3.5 billion years. Until about 575 million years ago, all life was microscopic plant life. Before that time, life in the Antarctic was very different from the way it[…]
Our own species — Homo sapiens — lived alongside other groups that split off from the same genetic family tree at different times. About 50,000 years ago, ancient humans in what is now West Africa apparently procreated with another group of ancient humans that scientists didn’t know existed. There aren’t any bones or ancient DNA[…]
According to folklore, such tiny, hairy people as her once roamed the tropical forests alongside modern humans. An ancient legend from the Indonesian island of Flores speaks of a mysterious, wild grandmother of the forest who eats everything: the ‘ebu gogo’. According to folklore, such tiny, hairy people as her once roamed the tropical forests[…]
Dioramas have a powerful explanatory power as tangible reconstructions. Introduction His eyes were vacant—glassy, even. Blood flowed from his head and his hands dragged next to him, fingers rolling lifelessly in the brown African dirt. His mouth was frozen open in terror, his head firmly clenched between a leopard’s jaws. The cat’s snarl was practically[…]
We have more neurons in our cortices than any other species, courtesy of an early technology – and along with them came our long, slow lives. Here’s something new to consider being thankful for at the dinner table: the long evolutionary journey that gave you your big brain and your long life. Courtesy of our[…]
Researchers say it’s time to finally discard a decades-old theory about the origins of human language. Introduction Sound doesn’t fossilize. Language doesn’t either. Even when writing systems have developed, they’ve represented full-fledged and functional languages. Rather than preserving the first baby steps toward language, they’re fully formed, made up of words, sentences and grammar carried[…]
Studying animal tooling can provide clues to the mysteries of human evolution. Human beings used to be defined as “the tool-maker” species. But the uniqueness of this description was challenged in the 1960s when Dr. Jane Goodall discovered that chimpanzees will pick and modify grass stems to use to collect termites. Her observations called into[…]
Lately, much news from the field of paleoarchaeology and anthropology has centered on Neanderthal bedfellows. By Dr. Anna GoldfieldArchaeologist In a cave tucked into the limestone hills of the Asturias region of Spain, there lie the remains of a group of 13 Neanderthals that date to between 50,600 and 47,300 years ago. The site is[…]
At the very least, in order for spoken language to be a possibility, a species has to have the right anatomical equipment. By Dr. Anna GoldfieldArchaeologist The first two pages of Claire Cameron’s novel The Last Neanderthal contain a glossary—a handful of words used by the family of Neanderthals at the center of the story.[…]
Was there something about the Neanderthals’ cognitive capacity that didn’t measure up? By Dr. Anna GoldfieldArchaeologist One of the most tantalizing topics about Neanderthals is their cognition: how it developed and whether it was much different from patterns of thought in Homo sapiens. We know from the archaeological record that much of Neanderthal hunting, foraging,[…]
Understanding their population has helped us to understand what it is to be human. By Anna GoldfieldArchaeologist In 1856, a scattered collection of bones was found in the Feldhofer Cave of the Neander Valley in Germany. Scientists had never seen anything like it. The skull resembled that of a human, but it had a low,[…]
Paleoanthropologist Carol Ward explains how walking upright marked a milestone in hominin history. By Dr. Tom GarlinghouseArchaeologist/Anthropologist Bipedality, the ability to walk upright on two legs, is a hallmark of human evolution. Many primates can stand up and walk around for short periods of time, but only humans use this posture for their primary mode[…]
Some populations of Neanderthals were definitely more carnivorous than others. By Dr. Anna GoldfieldArchaeologist One of the more tenacious misconceptions about Neanderthals is that they were exclusively meat eaters. Sure, in some of the colder regions of Europe plant food would have been very seasonally limited, so meat was almost certainly a large part of[…]
Even genetics support the idea that Neanderthals were better sprinters than runners. By Dr. Anna GoldfieldArchaeologist If you’re like me, you view long-distance running as a somewhat unrealistic aspiration and see those people who do it well as remarkable creatures. The truth, though, is that Homo sapiens are well-designed for loping along for long distances[…]
The bones show interbreeding Neanderthal and Denosivan humans. This article reprinted from RFE/RL. A piece of bone from a cave in Russia has yielded what may be the biggest archaeological find of the year, media reported on August 30. The bone belonged to an ancient human who had a Neanderthal mother and a Denisovan father.[…]
If you go by editorial cartoons and T-shirts, you might have the impression that evolution proceeds as an orderly march toward a preordained finish line. But that’s not right at all. Introduction Evolution doesn’t follow a preordained, straight path. Yet images abound that suggest otherwise. From museum displays to editorial cartoons, evolution is depicted as[…]
