An AI trained on 8,340 charred seeds from 18 Chinese sites now classifies ancient crops with 90% accuracy, by learning the same size-first trick archaeobotanists use at the microscope. #Archaeobotany #AncientDNA www.anthropology.net/p/teaching-a...
Teaching a Machine to Sort Five Thousand Years of Charred SeedsAn AI system trained on 8,340 charred seed images now does in seconds what took archaeobotanists years to learnwww.anthropology.netScientists just found DNA from two human relatives we’ve never found a single fossil of, hiding in modern genomes. One mixed with us in Africa 800,000 years ago; the other reached us secondhand, through Denisovans. #paleoanthropology #humanevolution #ancientDNA www.anthropology.net/p/two-ghosts...

Two Thumbnail-Sized Birds, Carved 40,000 Years AgoWhat a pair of miniature ivory figurines from Hohle Fels Cave reveal about the earliest known figurative artwww.anthropology.netA LiDAR survey of the Amazon just revealed a civilization ten times larger than expected: 24,000+ earthworks, up to 3 million people, and a forest reshaped by human hands for 1,500 years. #Archaeology #Amazon www.anthropology.net/p/a-civiliza...
A Civilization for Three Million People Left Almost No Trace Above GroundNew LiDAR surveys reveal that the Aquiry, a network of societies in southwestern Amazonia, built tens of thousands of monumental earthworks and shaped the rainforest for fifteen centurieswww.anthropology.netDid humans invent pet-keeping, or refine a primate trait? A new study of 427 cases shows primates adopting, grooming & bonding across species. With female-skewed care mirroring ethnographic data, our bond with animals is older than Homo sapiens. #Anthropology #Primatology #Domestication

What Flat Heads Tell Us About a Million Years of Difficult BabiesSkull deformity turns out to be a surprisingly direct fossil record of parental exhaustionwww.anthropology.netNew study compares 60 ethnographic and 49 archaeological societies and finds burying the dead at home was far more common in the deep past than anthropologists realized, before colonialism and religious conversion reshaped the practice. #Archaeology #Bioarchaeology #Ethnography #Burials #Culture
The Dead Who Lived With YouWhat a new study of burials worldwide reveals about the strange, recent split between homes for the living and places for the deadwww.anthropology.netA cave 4,000m up in Ladakh just revealed a lost population: people with ancestry split almost perfectly between South Asians and Tibetans, mixing began ~2800 years ago, and one still carries a Denisovan altitude gene. #AncientDNA #Paleoanthropology #Archaeogenetics
Ancient Genomes from a Cave Above the Clouds Reveal an Unknown Himalayan PopulationHow a scatter of bones 4,000 meters up in Ladakh rewrote the genetic history of a mountain crossroadswww.anthropology.net2,700 years ago at an Iron Age cemetery in Italy, men ate more meat than women, some people were buried far from home, and rich graves didn’t mean richer diets.

New modeling shows the population was too small to be self-sustaining, meaning repeated sea crossings, not isolation, kept them there. 🏝️🧬🌊 #Archaeology #Mesolithic www.anthropology.net/p/maltas-imp...
Malta’s Impossible MesolithicWhat a population model reveals about foragers who shouldn’t have survived on a 252 square kilometer island for a thousand yearswww.anthropology.netExcavate a site and you destroy it. The data you record is the only version of that moment that will ever exist. A new study of Catalan archaeologists shows how they’re improvising ways to save it. #Archaeology #DataManagement #OpenScience
Every Excavation Is a Deadline You Didn’t Know You HadCatalan archaeologists have built decades of careful, improvised systems for saving their data.
