The 2011 Holiday Lectures are now available on demand!
Where and when did humans arise? What distinguishes us from other species? Did our distant ancestors look and behave like us? When Darwin proposed that humans evolved from a common ancestor with the great apes, he lacked fossil evidence to support his idea. One hundred and fifty years later, the evidence for human evolution is plentiful and growing, including detailed molecular genetics data, an impressive fossil record, and artifacts of early human culture like stone tools. Leading scientists John Shea of Stony Brook University, Sarah Tishkoff of the University of Pennsylvania, and Tim White of the University of California, Berkeley, guide us on a global exploration spanning millions of years to illuminate the rise of modern humans.

Explore the Virtual Transgenic Fly Lab. The lab will familiarize you with the science and techniques used to make transgenic flies. Transgenic organisms, which contain DNA that is inserted experimentally, are used to study many biological processes. In this lab, you will create a transgenic fly to study circadian rhythms. The fly glows only when a certain gene involved in circadian rhythms is activated. After making the glowing fly, you will use it to explore basic principles of circadian biology and genetics. Enter the lab...
