In this SciCafe, biological anthropologist Dr. Habiba Chirchir will explore the evolution of the slender-boned skeletons that characterize modern humans.

In this talk, Dr. Jennifer Raff will explore the latest genetic and archaeological evidence for the origins of the First Peoples. We'll piece together a story told by DNA fragments recovered from a tooth in Siberia, a broken knife found deep beneath a muddy pond in Florida, and children's footprints left thousands of years ago on the shores of an ancient lake in New Mexico. We'll examine why these same pieces of evidence can lead to different interpretations among scholars and how they align—or don't—with the ancient knowledge held by present-day Indigenous descendants.
