    Scientists battle over whether violence has declined over time

    Contrary to a popular idea among researchers, modern states haven’t dulled people’s long-standing taste for killing each other in battle, a controversial new study concludes. But living in a heavily populated society may up one’s odds of surviving a war, two anthropologists propose.

    As a population grows, larger numbers of combatants die in wars, but those slain represent a smaller...

    Ancient humans avoided inbreeding by networking

    DNA of people who lived around 34,000 years ago reveals an especially lively social scene that may have been a key to humans’ evolutionary success.

    Much like hunter-gatherers today, ancient Eurasians married outside their home groups and formed webs of friends and in-laws vital for eventually building cities and civilizations, a new study suggests.

    Long-gone hunter-gatherers lived...

    Christina Warinner uncovers ancient tales in dental plaque

    Christina Warinner, 37Molecular anthropologistUniversity of OklahomaMax Planck Institute for theScience of Human History

    In a pitch-black rainforest with fluttering moths and crawling centipedes, Christina Warinner dug up her first skeleton. Well, technically it was a full skeleton plus two headless ones, all seated and draped in ornate jewelry. To deter looters, she excavated through the night...

    The rise of agricultural states came at a big cost, a new book argues

    Against the GrainJames C. ScottYale Univ., $26

    Contrary to popular opinion, humans didn’t shed a harsh existence as hunter-gatherers and herders for the good life of stay-in-place farming. Year-round farming villages and early agricultural states, such as those that cropped up in Mesopotamia, exchanged mobile groups’ healthy lifestyles for the back-breaking drudgery of cultivating crops...

    Ancient boy’s DNA pushes back date of earliest humans

    A boy who lived in what’s now South Africa nearly 2,000 years ago has lent a helping genome to science. Using the long-gone youngster’s genetic instruction book, scientists have estimated that humans emerged as a distinct population earlier than typically thought, between 350,000 and 260,000 years ago.

    The trick was retrieving a complete version of the ancient boy’s DNA from his skeleton...

    Neandertal kids were a lot like kids today — at least in how they grew

    A Neandertal child whose partial skeleton dates to around 49,000 years ago grew at the same pace as children do today, with a couple of exceptions. Growth of the child’s spine and brain lagged, a new study finds.

    It’s unclear, though, whether developmental slowing in those parts of the body applied only to Neandertals or to Stone Age Homo sapiens as well. If so, environmental conditions...

    Readers ponder mini-spacecraft and Canaanites’ genomes

    Spritely voyage

    Engineers recently launched prototypes of miniature spacecraft. The prototypes, each a single circuit board, include solar panels, radios, thermometers and gyroscopes, Maria Temming reported in “These chip-sized spacecraft are the smallest space probes yet” (SN: 9/2/17, p. 5).

    “Does the gyroscope actually stabilize the chip, or just provide information that can be signaled...

    Skeleton ignites debate over whether women were Viking warriors

    Viking warriors have a historical reputation as tough guys, with an emphasis on testosterone. But scientists now say that DNA has unveiled a Viking warrior woman who was previously found in a roughly 1,000-year-old grave in Sweden. Until now, many researchers assumed that “she” was a “he” buried with a set of weapons and related paraphernalia worthy of a high-ranking military officer.

    If...

    Science can’t forecast love

    Here’s some heartbreaking news for people pinning their hopes on online matchmaking sites: It’s virtually impossible to forecast a love connection.

    Maybe that’s not so shocking to survivors of the dating wars. But now science is weighing in. Extensive background data on two individuals — comparable to that collected by digital dating services — can’t predict whether that pair will...

    Readers were curious about rogue planets, exomoons and more

    Going rogue

    Astronomers estimate that wandering Jupiter-mass planets without a parent star are about a tenth as common as once believed, Ashley Yeager reported in “Giant solo planets are in limited supply” (SN: 8/19/17, p. 10).

    Online reader Brian Bixby wondered how often such a rogue planet would come close to our solar system and proposed that one near the Kuiper Belt or Oort cloud...
