Traders brought Central American cacao to Georgia 1,000 years ago (opens the original)
Read excerpt
A thousand years ago, feasts in what’s now northern Georgia state included cacao from Central America. Potsherds discarded after an 11th-century feast at Etowah—an Indigenous city just north of what’s now Atlanta—contained traces of cacao, a raw ingredient of chocolate. The chemical residue and ancient DNA reveal that not only did the Mississippian people who built the city have excellent taste, they also had trade connections that reached at least 3,000 kilometers to Central America. And in a s
Meet the only known trebuchet casualty in history (opens the original)
Read excerpt
During a medieval siege, a trebuchet scored a chance hit on one unlucky defender. A small boulder slammed into his upper back at close to 300 kilometers an hour, smashing bones and crushing him beneath its weight. The man’s skeleton lay beneath the chapel of Scotland’s Stirling Castle, along with the remains of several other people who had clearly died violent deaths. But this one, known to us only as Skeleton 150 (or as “trebuchet guy” in your faithful correspondent’s notes), stood out even amo
Did poop enable the evolution of complex animals? (opens the original)
Read excerpt
The Cambrian explosion may have been fueled by poop. The first animals on Earth emerged about 600 million years ago, and 60 million years later, those simple early animals evolved in wildly different directions, branching out into a diverse menagerie of complicated new forms and conquering new ecological niches. Known as the Cambrian Explosion, this flurry of rapid evolution produced most of the animal phyla and ecosystems we see around us today. And it may have taken off because some of those e
Flores Hobbits' eating habits offer clues about their evolutionary past (opens the original)
Read excerpt
Until about 60,000 years ago, diminutive hominin cousins, Homo floresiensis (affectionately nicknamed Hobbits for obvious reasons), shared the island of Flores with Komodo dragons, pygmy elephants, and giant rats. Based on the presence of hominin and pygmy elephant bones in the same layers of cave sediment, it originally looked like the Hobbits had hunted and butchered dwarf elephants—an impressive feat for such a tiny hominin. But according to University of Tübingen anthropologist Elizabeth Vea
