Nature reports: A fossilized jawbone discovered in a cave in eastern China bears a curious mix of ancient and modern features, according to a detailed analysis that compares it with dozens of other human specimens. The finding, published in the Journal of Human Evolution, indicates that the 300,000-year-old bone could have belonged to an as-yet… Read More »
Live Science reports: Archaeologists have discovered the oldest evidence yet of a wooden structure crafted by the hands of a human ancestor. Two tree trunks, notched like Lincoln Logs, were preserved at the bottom of the Kalambo River in Zambia. If the logs’ estimated 476,000-year-old age is correct, it means that woodworking might predate the… Read More »
Michael Segalov writes: “We might not know much about Neanderthals,” [says Ludovic Slimak], “but through what they created, we can see something incredible. When you take Home Sapien tools made of flint, spanning tens of thousands of years, in different parts of the world, they’re always the same. Standardised. It can’t be cultural.” There was… Read More »
The Cambrian explosion, about 530 million years ago, was when most of the major groups of animals first appear in the fossil record. canbedone/Shutterstock By Matthew Wills, University of Bath and Marcello Ruta, University of Lincoln Depending upon how you do the counting, there are around 9 million species on Earth, from the simplest single-celled… Read More »
Ars Technica reports: Multiple lines of evidence indicate that modern humans evolved within the last 200,000 years and spread out of Africa starting about 60,000 years ago. Before that, however, the details get a bit complicated. We’re still arguing about which ancestral population might have given rise to our lineage. Somewhere about 600,000 years ago,… Read More »
Live Science reports: An ape fossil found in Turkey may controversially suggest that the ancestors of African apes and humans first evolved in Europe before migrating to Africa, a research team says in a new study. The proposal breaks with the conventional view that hominines — the group that includes humans, the African apes (chimps,… Read More »
The New York Times reports: It’s often viewed as a given: Men hunted, women gathered. After all, the anthropological reasoning went, men were naturally more aggressive, whereas the slower pace of gathering was ideal for women, who were mainly focused on caretaking. “It’s not something I questioned,” said Sophia Chilczuk, a recent graduate of Seattle… Read More »
The New York Times reports: Of all the long-running disputes in archaeology, few roil scholars more than the question of when humans arrived in the Americas. For much of the past century, the reigning theory was that in or around 11,500 years ago big-game hunters from Asia trudged to North America across a land bridge… Read More »
Live Science reports: Since its discovery in 2008, the skeleton of a high-ranking individual buried inside a tomb in the Iberian Peninsula between 3,200 and 2,200 years ago was thought to be the remains of a man. However, a new analysis reveals that this person was actually a woman. Archaeologists in Spain dubbed the woman… Read More »
Carl Zimmer reports: In 2015, scientists reported an astonishing discovery from deep inside a South African cave: more than 1,500 fossils of an ancient hominin species that had never been seen before. The creatures, named Homo naledi, were short, with long arms, curved fingers and a brain about one-third the size of a modern human’s.… Read More »
Neanderthals were evolutionary cousins to our species, Homo sapiens. Chettaprin.P / Shutterstock By Bethan Linscott, University of Oxford The region of Estremadura in Portugal was home to a band of Neanderthals – an ancient evolutionary relative of modern humans – about 95,000 years ago. They made use of the patchwork of limestone caves, crags and… Read More »
Shutterstock By Ray Tobler, Australian National University; Shane T Grey, Garvan Institute, and Yassine Souilmi, University of Adelaide Most scientists agree modern humans developed in Africa, more than 200,000 years ago, and that a great human diaspora across much of the rest of the world occurred between perhaps 60,000 and 50,000 years ago. In new… Read More »
The Guardian reports: Prehistoric humans in Europe might have been sitting round campfires built to toast snacks as early as 250,000 years ago – 50,000 years earlier than originally thought, researchers have suggested. Human species have a long association with fire, with some sites suggesting its controlled use dates back more than 700,000 years in… Read More »
Carl Zimmer reports: Scientists have revealed a surprisingly complex origin of our species, rejecting the long-held argument that modern humans arose from one place in Africa during one period in time. By analyzing the genomes of 290 living people, researchers concluded that modern humans descended from at least two populations that coexisted in Africa for… Read More »
Science Alert reports: Like treasured recipes passed down from generation to generation, there are just some regions of DNA that evolution doesn’t dare tweak. Mammals far and wide share a variety of such encoded sequences, for example, which have remained untouched for millions of years. Humans are a strange exception to this club. For some… Read More »
The Observer reports: It took three separate waves of modern humans to colonise Europe between 54,000 and 42,000 years ago. That is the key conclusion of scientists who have been studying caves in the Rhone valley where they have discovered evidence that Homo sapiens had to make a trio of determined attempts to head westwards… Read More »
