Alan Alda, Series Producer Graham Chedd, and Executve Producer Jared Lipworth participated in a live webcast this week, hosted by the National Science Foundation.

We took a look inside Alan's brain using an MRI machine. Apparently he has quite a plump hippocampus.

Dan Gilbert and Alan Alda discuss whether animals have the ability to "prospect," or plan ahead.

Producer Graham Chedd thought a chat en plein air would add some visual variation from the two-guys-sitting-on-a-couch-type shot that's always easy to get in a professor’s office.

Amanda Henry showed us how she very gently scrapes dental plaque from the Skhul 5 skull’s molars to find out what our ancestors may have eaten.

We went to the North Carolina Zoo to meet the chimpanzees -- and evolutionary anthropologist Brian Hare. Here's what happened...

We’ve just finished shooting at Duke University a series of experiments with Tanya Chartrand on how humans unconsciously mimic each other, and how this makes us more social.

In Arizona, Alan and archeologist Curtis Marean had a fireside chat about how modern humans replaced the Neanderthals. Check out this video to see how the scene was made.

Graham Chedd tells the story of what happened at the European Synchrotron Radiation Facility, where researchers were examining Neanderthal teeth with a high-power x-ray.

How long did it take Neanderthals to grow up? Graham Chedd meets with researchers who are using a giant particle accelerator to find an answer to this question.
