All baby birds have a moment prior to hatching when their hip bone is a tiny replica of a dinosaur’s pelvis. That’s one of the findings in a new, Yale-led study in the journal Nature that explores the evolutionary underpinnings of the avian hip bone. It is also a modern-day nod to the dramatic transformation that led from dinosaurs to birds over tens of millions of years.
