    Chaco Canyon’s ancient civilization continues to puzzle

    Chaco Canyon is a land of extremes. Summer heat scorches the desert canyon, which is sandwiched between sandstone cliffs nearly two kilometers above sea level in New Mexico’s northwestern corner. Bitter cold sweeps in for winter. Temperatures can swing as many as 28 degrees Celsius during the course of a day. Through it all, Chaco Canyon maintains a desolate beauty and a craggy pride as home...

    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...

    Written in bone

    Carles Lalueza-Fox nearly missed an opportunity to paint the genetic portrait of a 7,000-year-old Spaniard.

    In 2006, spelunkers stumbled across the ancient remains of two men in a cave in Spain’s Cantabrian mountain range. Lalueza-Fox, an evolutionary geneticist at the Institute of Evolutionary Biology in Barcelona, got a call inviting him to examine the skeletons’ DNA.

    “I told...

    DNA tracks ancient Mediterranean farmers to Scandinavia

    Modern Europeans’ genetic profile may have been partly cultivated by early Mediterranean farmers who moved to what’s now Scandinavia, where they paired up with resident hunter-gatherers.

    DNA taken from 5,000-year-old skeletons previously excavated in Sweden unveils a scenario in which agricultural newcomers from the south interbred with northern hunter-gatherers, say...

    As the worms churn

    To celebrate the 200th anniversary of Charles Darwin’s birth, hordes of readers are reveling in On the Origin of Species, which sets forth the case for evolution via natural selection. Others are poring over The Voyage of the Beagle, the chronicle of Darwin’s five-year, round-the-world expedition.

    It’s probably safe to say, however, that only die-hard...

    Oh, rats — there go the snails

    Rats keep getting into paradise. And when they discover a taste for escargot, it’s an infernal problem for native populations.

    At a study site high in the mountains on the Hawaiian island of Molokai, tree snails of the species Partulina redfieldi thrived for 12 years and then declined catastrophically, says zoologist Michael G. Hadfield of the University of Hawaii at...

    Tuning In to Science

    In its own way, science is a lot like '60s rock 'n' roll on AM radio. If you're old enough, you remember the slogan: "And the hits just keep on comin'."

    With science, the news just keeps on comin'. Somehow, year after year, science never runs out of hit discoveries. From land-based laboratories to the depths of the oceans to remote realms of the cosmos, intrepid...

    Living History

    Tourists who visit the Maya temples at Ek' Balam in Yucatán, Mexico, aren't allowed to pocket souvenir chunks of the intricate carvings on the centuries-old buildings. Visitors aren't supposed to even touch the soft limestone with their hands for fear they'll rub away the structures' delicate sculptural details. Yet even as Ek' Balam's caretakers keep people from destroying the archaeological...

    Cultivating Revolutions

    Nearly 80 years ago, the British archaeologist V. Gordon Childe championed a theory of what he called a revolution in food production during the Neolithic age. Childe proposed that hunting-and-gathering groups in the Middle East had been the first people to grow crops, raise animals for food, and live year-round in villages—around 10,000 years ago. In his scenario, farmers then spread into...
