Scientists from Leiden University and Delft University of Technology think that Neanderthals that lived at the site of Pech-de-l'Azé some 50,000 years ago may have used manganese dioxide to help kindle their fires. It had been thought that the blocks of manganese oxides found at Neanderthal sites in France were used for body decoration, but soot from their fires would have been readily available for use as a dark pigment. Why would Neanderthals go to the trouble to collect this mineral? Peter J. Heyes, Konstantinos Anastasakis, Wiebren de Jong, Annelies van Hoesel, Wil Roebroeks, and Marie Soressi found that although...

Mysterious MigrationsOur prehistoric ancestors journeyed out of Africa on contested roads Bruce Bower It was the most momentous immigration ever, a population realignment that marked a startling departure for our species, Homo sapiens. After emerging in eastern Africa close to 200,000 years ago, anatomically modern people stayed on one continent for roughly 140,000 years before spreading out in force around the world. Then, from 40,000 to 35,000 years ago, our forerunners advanced into areas stretching from what is now France to southeastern Asia and Australia. DIGGING THE PAST. Workers excavate deep into a site near the Russian village of Kostenki,...

Ever since geneticists sequenced the first Neanderthal genome in 2010, researchers have been reporting just how related humans are to their ancient, extinct cousins. Since then, there's been more research. And more. And more. As it turns out, non-African modern humans have Neanderthals to thank for 1 to 4 percent of their DNA. The two species were thought to have interbred around 50,000 to 60,000 years ago, based on the Neanderthal DNA found in anatomically modern human specimens and people living today. But scientists had yet to find a signature of such mating interactions in Neanderthal DNA, until now. "Instead...

Ancient trysts between Neanderthals and modern humans may have influenced modern risks for depression, heart attacks, nicotine addiction, obesity and other health problems, researchers said. Some of the scientists' discoveries confirm previous ideas. For example, earlier research suggested that Neanderthal DNA influenced skin cells known as keratinocytes that help protect the skin from environmental damage such as ultraviolet radiation and germs. The new findings suggest that Neanderthal genetic variants increase the risk of developing sun-triggered skin lesions known as keratoses, which are caused by abnormal keratinocytes.

When modern humans met Neanderthals in Europe and the two species began interbreeding many thousands of years ago, the exchange left humans with gene variations that have increased the ability of those who carry them to ward off infection. This inheritance from Neanderthals may have also left some people more prone to allergies. Researchers of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and the Institut Pasteur and the CNRS in Paris, France, report about the discoveries in two independent studies, adding to evidence for an important role for interspecies relations in human evolution and specifically in the...

As the terrorist group ISIS is pushed out of northern Iraq, archaeologists are resuming work in the region, making new discoveries and figuring out how to conserve archaeological sites and reclaim looted antiquities. Several discoveries, including new Neanderthal skeletal remains, have been made at Shanidar Cave, a site in Iraqi Kurdistan that was inhabited by Neanderthals more than 40,000 years ago. Additionally, though ISIS did destroy and loot a great number of sites, there are several ways for archaeologists, scientific institutions, governments and law enforcement agencies in North America and Europe to help save the region's heritage, said Dlshad Marf...

Most recent dating places one wave of human dispersal out of Africa into southeastern Spain at almost one million years ago. Using state-of-the-art dating methodologies, a team of scientists have obtained or confirmed a date range between .9 and .85 Mya (million years ago) as a time when a species of Old World monkey (Theropithecus) and an early species of human occupied the cave site of Cueva Victoria in southeastern Spain. It is a location not far from where many scientists have hypothesized that humans may have crossed over into Europe from North Africa through the Strait of Gibraltar at...

Modern science has held that islands such as Cypress and Crete were first inhabited by seafaring humans approximately 9,000 years ago by agriculturists from the late Neolithic period. Simmons writes that research over the past 20 years has cast doubt on that assumption however and suggests that it might be time to rewrite the history books. He cites evidence such as pieces of obsidian found in a cave in mainland Greece that were found to have come from Melos, an island in the Aegean Sea and were dated at 11,000 years ago as well as artifacts from recent digs on...

Archaeologists on the island of Crete have discovered what may be evidence of one of the world's first sea voyages by human ancestors, the Greek Culture Ministry said Monday A ministry statement said experts from Greece and the U.S. have found rough axes and other tools thought to be between 130,000 and 700,000 years old close to shelters on the island's south coast. Crete has been separated from the mainland for about five million years, so whoever made the tools must have traveled there by sea (a distance of at least 40 miles). That would upset the current view that...

Human ancestors that left Africa hundreds of thousands of years ago to see the rest of the world were no landlubbers. Stone hand axes unearthed on the Mediterranean island of Crete indicate that an ancient Homo species -- perhaps Homo erectus -- had used rafts or other seagoing vessels to cross from northern Africa to Europe via at least some of the larger islands in between, says archaeologist Thomas Strasser of Providence College in Rhode Island. Several hundred double-edged cutting implements discovered at nine sites in southwestern Crete date to at least 130,000 years ago and probably much earlier, Strasser...

<p>Early humans, possibly even prehuman ancestors, appear to have been going to sea much longer than anyone had ever suspected.</p> <p>That is the startling implication of discoveries made the last two summers on the Greek island of Crete. Stone tools found there, archaeologists say, are at least 130,000 years old, which is considered strong evidence for the earliest known seafaring in the Mediterranean and cause for rethinking the maritime capabilities of prehuman cultures.</p>

After years of studying a mysterious thigh bone from a cave in China, scientists said on Thursday they believe it represents an ancient species of human that persisted much longer than previously thought. The 14,000-year-old bone was uncovered in 1989 in Maludong, known as the Red Deer Cave. The trove of fossils it was initially found with went unstudied until 2012. The partial femur, though relatively young in age, looks like the bones of far older species like Homo habilis and early Homo erectus that lived more than 1.5 million years ago, said the study in PLOS ONE. "Its young...

A 14,000-year-old thigh bone may upend human history. Unearthed in southwest China, this femur resembles those of an ancient species of humans thought to be long extinct by the Late Pleistocene, scientists say. The scientists compare the leg bone to ancient and modern human femurs in a paper published Thursday in the journal PLOS ONE, arguing that this specimen represents a population of ancient humans that lived surprisingly recently. If they're right, this could dramatically change the way we see human history. Today, our species, Homo sapiens, are the only humans to walk the Earth. But it hasn't always been...

A 14,000-year-old fragment of thigh bone found in a cave in China may represent evidence of the unexpected survival of long-vanished human ancestors. If so, then right into and through the ice age, a creature that was either Homo habilis or Homo erectus survived alongside the Neanderthals, the unknown humans who left behind some DNA in a cave in Siberia, the mysterious so-called hobbit of the island of Flores in Indonesia, and modern Homo sapiens. But by the end of this multicultural ice age 10,000 years ago, only one human species survived. The fossil, a partial femur, had survived unstudied...

Neanderthal man arrived on the Italian peninsular some 100,000 years earlier than previously thought, according to a study set to be published this month. The discovery was made after researchers analyzed radioactive deposits that were found in sediments present inside two Neanderthal skulls unearthed in a gravel pit Saccopastore, Lazio, in the 1930s. The site of the dig is now occupied by an eastern section of Rome's ring road. "The results of our studies show that the Saccopastore remains are 100,000 years older than previously thought -- and push back the arrival of Neanderthal man in Italy to 250,000 years...

Forty-seven smooth teeth dug out of a cave in southern China reveal that Homo sapiens may have arrived there 80,000 years ago...The findings, published this week in the journal Nature, may compel researchers to reconsider their theories about human migrations out of Africa.

I just finished the strangest, most disconcerting little book. It's called Why Do People Sing?: Music in Human Evolution by Joseph Jordania. If the title hasn't already piqued your interest, its thesis surely will. The thesis is wild, bold, and original, but makes an eerie amount of sense. If true, it would be a revolution — and I don't use the term lightly — in how we understand the evolution of music, cooperation, warfare, and even religion.

They are one of our closest human relatives and dominated Europe and much of Asia for hundreds of thousands of years, but Neanderthals may be far older than previously thought. A new study by geneticists has revealed a collection of fossilised bones discovered in a cave in northern Spain belonged to an early member of the Neanderthal family. It is the oldest partial genome from early human fossils ever to be sequenced and pushes back the date for the origins of the Neanderthal branch of our evolutionary tree by up to 300,000 years....

Nobody likes going to the dentist, but redheads may have good reason. A growing body of research shows that people with red hair need larger doses of anesthesia and often are resistant to local pain blockers like Novocaine. As a result, redheads tend to be particularly nervous about dental procedures and are twice as likely to avoid going to the dentist as people with other hair colors, according to new research published in The Journal of the American Dental Association. Researchers believe redheads are more sensitive to pain because of a mutation in a gene that affects hair color. In...
