Feature: Solving the mystery of dog domestication
COLUMBUS, OHIO—A
prehistoric dog is about to go to the dentist. Ardern Hulme-Beaman, a
lanky 27-year-old Irish postdoc, pulls on a white facemask and lifts a
small 5000-year-old jawbone from a cardboard box. He places a gloved
hand over one of the molars and gently tugs from side to side until it
pops out. The jagged top of the tooth is yellowish white, but the roots
are dirty brown. Hulme-Beaman powers on a drill, and a circular blade
screeches into a root. The scent of burning hair fills the air. “That's a
good sign,” he says. “It means there's DNA here.”
