    Peru’s famous Nazca Lines may include drawings of exotic birds

    Massive drawings of birds etched by pre-Inca people on southern Peru’s Nazca desert plateau include several exotic surprises, Japanese researchers say.

    Three avian images depict species that live far outside the region where the famous drawings were created, zooarchaeologist Masaki Eda of Hokkaido University Museum and his colleagues conclude. A drawing previously classified as a...

    Capuchin monkeys’ stone-tool use has evolved over 3,000 years

    Excavations in Brazil have pounded out new insights into the handiness of ancient monkeys.

    South American capuchin monkeys have not only hammered and dug with carefully chosen stones for the last 3,000 years, but also have selected pounding tools of varying sizes and weights along the way.

    Capuchin stone implements recovered at a site in northeastern Brazil display signs of shifts...

    People may have smoked marijuana in rituals 2,500 years ago in western China

    Mourners gathered at a cemetery in what’s now western China around 2,500 years ago to inhale fumes of burning cannabis plants that wafted from small wooden containers. High levels of the psychoactive compound THC in those ignited plants, also known as marijuana, would have induced altered states of consciousness. 

    Evidence of this practice comes from Jirzankal Cemetery in Central Asia’s...

    These knotted cords may hide the first evidence that the Incas collected taxes

    While excavating an Inca outpost on Peru’s southern coast, archaeologist Alejandro Chu and his colleagues uncovered some twisted surprises.

    In 2013, the scientists were digging in one of four rooms lining the entrance to what had been a massive storage structure, and they started finding sets of colored and knotted strings poking through the ground. Known as khipus, these odd Inca...

    Hominids may have been cutting-edge tool makers 2.6 million years ago

    Discoveries in East Africa of what may be the oldest expertly sharpened stone implements suggest that early members of the human genus, Homo, invented these tools by around 2.6 million years ago, researchers say. But their conclusions are controversial.

    New finds at a site in Ethiopia called Ledi-Geraru fit a scenario in which various early Homo groups devised ways to sharpen handheld...

    Cave debris may be the oldest known example of people eating starch

    Small fire pits in a South African cave have yielded what researchers regard as the oldest known examples of a key dish in ancient humans’ daily menu. No, not dessert. Think roasted plant starches.

    Charred plant remains found in Klasies River Cave date to as early as around 120,000 years ago, and as late as roughly 65,000 years ago, say archaeologist Cynthia Larbey of the University of...

    Ancient South American populations dipped due to an erratic climate

    Ancient South American populations declined sharply as rainfall became increasingly unpredictable starting around 8,600 years ago, researchers say.

    But hunter-gatherer groups from the Andes and the Amazon to the continent’s southern tip bounced back quickly once rain returned to a relatively stable pattern about 6,000 years ago, report archaeologists Philip Riris and Manuel Arroyo-Kalin...

    An ancient pouch reveals the hallucinogen stash of an Andes shaman

    A leather bag stuffed with ritual items, found high in the Andes Mountains, has yielded rare clues to South American shamans’ hallucinatory visions around 1,000 years ago.

    One artifact in the radiocarbon-dated bag, a pouch stitched out of three fox snouts, contains chemical traces of five mind-altering substances obtained from at least three plants, say bioarchaeologist Melanie Miller of...

    Excavations show hunter-gatherers lived in the Amazon more than 10,000 years ago

    Hunter-gatherers occupied the southwestern Amazon rainforest by around 10,600 years ago — at least several thousand years earlier than previously thought.

    Excavated food remains and human burials at several locations in Bolivia support a scenario in which hunter-gatherers regularly occupied those spots for large parts of the year. The unearthed evidence also indicates that the hunter-...

    Ancient sculptors made magnetic figures from rocks struck by lightning

    People living at least 2,000 years ago near the Pacific Coast of what’s now Guatemala crafted massive human sculptures with magnetized foreheads, cheeks and navels. New research provides the first detailed look at how these sculpted body parts were intentionally placed within magnetic fields on large rocks.

    Lightning strikes probably magnetized sections of boulders that were later carved...
