    First settlers reached Americas 130,000 years ago, study claims

    The New World was a surprisingly old destination for humans or our evolutionary relatives, say investigators of a controversial set of bones and stones.

    An unidentified Homo species used stone tools to crack apart mastodon bones, teeth and tusks approximately 130,700 years ago at a site near what’s now San Diego. This unsettling claim upending the scientific debate over the settling of...

    Oldest evidence of patterned silk loom found in China

    An ancient tomb in southern China has provided the oldest known examples, in scaled-down form, of revolutionary weaving machines called pattern looms. Four immobile models of pattern looms illuminate how weavers first produced silk textiles with repeating patterns. The cloths were traded across Eurasia via the Silk Road, Chinese archaeologists report in the April Antiquity. The models, created...

    How the house mouse tamed itself

    Got a mouse in the house? Blame yourself. Not your housekeeping, but your species. Humans never intended to live a mouse-friendly life. But as we moved into a settled life, some animals — including a few unassuming mice — settled in, too. In the process, their species prospered — and took over the world.

    The rise and fall of the house mouse’s fortunes followed the stability and...

    Shock-absorbing spear points kept early North Americans on the hunt

    Ancient North Americans hunted with spear points crafted to absorb shock.

    Clovis people, who crossed a land bridge from Asia to North America around 13,500 years ago, fashioned stone weapons that slightly crumpled at the base rather than breaking at the tip when thrust into prey, say civil engineer Kaitlyn Thomas of Southern Methodist University in Dallas and colleagues. The Clovis...

    Stone Age hunter-gatherers tackled their cavities with a sharp tool and tar

    Stone Age dentists didn’t drill and fill cavities. They scraped and coated them.

    Two teeth from a person who lived in what’s now northern Italy between 13,000 and 12,740 years ago bear signs of someone having scoured and removed infected soft, inner tissue. The treated area was then covered with bitumen, a sticky, tarlike substance Stone Age folks used to attach stone tools to handles (...

    Neandertals had an eye for patterns

    Neandertals knew how to kick it up a couple of notches. Between 38,000 and 43,000 years ago, these close evolutionary relatives of humans added two notches to five previous incisions on a raven bone to produce an evenly spaced sequence, researchers say.

    This visually consistent pattern suggests Neandertals either had an eye for pleasing-looking displays or saw some deeper symbolic...

    Palace remains in Mexico point to ancient rise of centralized power

    Remnants of a royal palace in southern Mexico, dating to between around 2,300 and 2,100 years ago, come from what must have been one of the Americas’ earliest large, centralized governments, researchers say.

    Excavations completed in 2014 at El Palenque uncovered a palace with separate areas where a ruler conducted affairs of state and lived with his family, say archaeologists Elsa...

    Ancient Romans may have been cozier with Huns than they let on

    Nomadic warriors and herders known as the Huns are described in historical accounts as having instigated the fifth century fall of the Roman Empire under Attila’s leadership. But the invaders weren’t always so fierce. Sometimes they shared rather than fought with the Romans, new evidence suggests.

    Huns and farmers living around the Roman Empire’s eastern border, where the Danube River...

    Ancient dental plaque tells tales of Neandertal diet and disease

    Dental plaque preserved in fossilized teeth confirms that Neandertals were flexible eaters and may have self-medicated with an ancient equivalent of aspirin.

    DNA recovered from calcified plaque on teeth from four Neandertal individuals suggest that those from the grasslands around Beligum’s Spy cave ate woolly rhinoceros and wild sheep, while their counterparts from the forested El...

    Ancient nomadic herders beat a path to the Silk Road

    Nomadic herders took the ancient Silk Road to new heights.

    Starting 4,000 years ago or more, Central Asian herders routinely migrated from highland pastures in summer to lowland areas in winter (SN: 5/3/14, p. 15). Over roughly the next 2,000 years, those routes through mountainous regions eventually became a key part of the Silk Road, an ancient trade and travel network stretching from...
