Attention to the Unseen

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 the “Ivory Lady” based on the bounty of grave goods found alongside her skeleton, including an ivory tusk surrounding her skull, flint, an ostrich eggshell,…

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. They lived around the time the first humans were roaming Africa. Now, after years of analyzing the surfaces and sediments of the elaborate underground cave,…

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 river valleys, leaving traces of their activities in the form of stone tools, butchered animal bones and the remnants of fireplaces. Now their teeth are…

In new research published in Proceedings of the National Academies of Sciences, we have uncovered dozens of distinctive historical changes in the human genome to reveal a…

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 Africa and the Middle East and at least 400,000 years in Europe. Now experts say they have found the earliest evidence in Europe for fires…

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 a million years before merging in several independent events across the continent. The findings were published on Wednesday in Nature. “There is no single birthplace,”…

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 and northwards from western Asia before they could establish themselves in the continent. “The first two of these waves failed but the third succeeded around…

Nature reports: In 2010, researchers published the first genome sequence from an ancient human, using tufts of hair from a man who lived around 4,000 years ago in Greenland. In the 13 years since, scientists have generated genome data from more than 10,000 ancient people — and there’s no sign of a slowdown. “I feel truly gobsmacked that we have gotten to this point,” says David Reich, a population geneticist at Harvard Medical School in Boston, Massachusetts. His team maintains…

Reuters reports: Europe was no balmy paradise during the Ice Age, with the vast glaciers that blanketed large parts of the continent rendering wide swathes inhospitable for humans. But our species – a new immigrant to Europe – endured, though with great hardship. Researchers on Wednesday unveiled an analysis of genome data from 356 hunter-gatherers who lived in the region between 35,000 and 5,000 years ago, a span that included the Ice Age’s coldest interval between 25,000 and 19,000 years…
