Every holiday season, penguins abound, both in the Museum of Science and History's Enchanted Forest exhibit and in holiday decorations worldwide.  So this year, we wanted to learn a little bit more about these unique birds and how they became the creatures we know today.  We talk to Daniel Ksepka, a paleontologist who studies the evolution of birds, about today's penguins as well as their ancient relatives, such as the giant Anthropornis.  Special thanks to Discoll for this image, as well as Boon, Sully Allen, and Purple Planet for the music in this episode.
