Neanderthals ‘self-medicated’ for pain

Neanderthals dosed themselves with painkillers and possibly penicillin, according to a study of their teeth. One sick Neanderthal chewed the bark of the poplar tree, which contains a chemical related to aspirin. He may also have been using penicillin, long … Continue reading

We Are All Africans

Every person’s DNA contains part of the human story: how our ancestors — lanky, tool-using apes — spread across the planet, colonizing environments as varied as the Himalayas, Arctic and Amazon Basin. Millions of people have had at least part … Continue reading

Scottish fossils tell story of first life on land

Fossils of what may be the earliest four-legged backboned animals to walk on land have been discovered in Scotland. The lizard-like creatures lived about 355 million years ago, when the ancestors of modern reptiles, birds and mammals emerged from swamps. … Continue reading

Anatomically Modern Humans

The term anatomically modern humans (AMH) refers in paleoanthropology to individual members of the species Homo sapiens with an appearance consistent with the range of phenotypes in modern humans. Anatomically modern humans evolved from archaic humans in the Middle Paleolithic, … Continue reading

Humans settled earlier in Australia’s remote outback

Humans started to settle inland Australia 10,000 years earlier than previously believed, scientists said Thursday, after discovering thousands of artefacts and bones in a rock shelter in the remote outback. People are thought to have arrived in Australia around 50,000 … Continue reading

New technique offers glimpse at human evolution in action

In research published in Science, a Stanford-led international team used a new analytic technique to map recent evolution. The technique relies exclusively on the DNA sequences of modern humans, yet it can reveal rapid changes in the prevalence of different … Continue reading

Guide to the Châtelperronian

The Châtelperronian period refers to one of five stone tool industries identified within the Upper Paleolithic period of Europe (ca 45,000-20,000 years ago). Once thought the earliest of the five industries, the Châtelperronian is today recognized as roughly coeval with … Continue reading

Biochronology

In paleontology, biochronology is the correlation in time of biological events using fossils. In its strict sense, it refers to the use of assemblages of fossils that are not tied to stratigraphic sections (in contrast to biostratigraphy, where they are). … Continue reading

Neanderthal diet like early modern human’s

Natural History Museum scientists, working as part of the Gibraltar Caves Project, excavated and studied remains of shell fish and other marine animals such as dolphins from two caves in Gibraltar where Neanderthals once lived and have discovered that Neanderthal … Continue reading

Physicists confirm there’s a second layer of information hidden in our DNA

DNA folding is an incredibly important control mechanism. That’s because every single cell in our body contains around 2 metres of DNA, so to fit inside us, it has to be tightly wrapped up into a bundle called a nucleosome – like … Continue reading

Rise of mammals ‘began well before dinosaur extinction’

Mammals began to flourish well before the end of the dinosaur age, a new study has found. The study saw hundreds of mammal fossil teeth analysed by the Universities of Southampton and Chicago. The findings showed those with varied diets … Continue reading

New Evidence Shows Peppered Moths Changed Color in Sync With the Industrial Revolution

Want to learn more about natural selection? Just look for a black peppered moth—Biston betularia. During the early 19th century in Britain, the moths used to have salt-and-pepper coloring. But over the years black versions of the moth began to prevail. … Continue reading

New insights on Late Pleistocene modern human diversity in Africa

Cover image Journal of Human Evolution

Although questions of modern human origins and dispersal are subject to intense research within and outside Africa, the processes of modern human diversification during the Late Pleistocene are most often discussed within the context of recent human genetic data. This … Continue reading

​​Neanderthals built complex underground structures 176,000 years ago – and no one knows why

Turns out we know a whole lot less about Neanderthals than we thought, because our cave-painting, tool-wielding, fire-conquering cousins were sophisticated enough to build complex subterranean structures as far back as 176,500 years ago, according to new archaeological evidence. Deep … Continue reading

Rare evolutionary event detected in the lab

DNA HardDrive

It took nearly a half trillion tries before researchers at The University of Texas at Austin witnessed a rare event and perhaps solved an evolutionary puzzle about how introns, non-coding sequences of DNA located within genes, multiply in a genome. … Continue reading

Life forms ‘went large’ a billion years ago

Life was already organising itself into large communities of cells more than a billion years ago, according to evidence from China. The centimetre-scale life forms were preserved in mudstones from the Yanshan area in the country’s north and are dated … Continue reading

The oldest human genome ever has been sequenced, and it could rewrite our history

Scientists have sequenced the oldest human DNA ever, extracted from 430,000-year-old samples of fossilised tooth and a thigh bones, found in Spain’s Sima de los Huesos, which translates to “pit of bones”. In doing so, the team from Germany has … Continue reading
