Penguins are familiar faces at zoos and aquariums, but they evolved long before humans. These fascinating birds have been around for more than 60 million years, during which they survived dramatic changes in climate, wholesale re-arrangements of the continents, and the rise of new mammalian competitors. Thanks to their dense bones, penguins have left behind a rich fossil record that we can use to trace their geographical expansion and morphological evolution. In this Science Cafe we will get to know some of the diverse cast of extinct penguins, including primitive species from the deep past, spear-billed penguins from Peru, and giants that would have towered over today's Emperor Penguins.
About the Speaker:
Dr. Daniel Ksepka is a paleontologist at North Carolina State University and a research associate at the North Carolina Museum of Natural Sciences. His research focuses on reconstructing the evolutionary tree of birds and understanding the transition from aerial flight to underwater wing-propelled diving in groups like penguins and the now extinct plotopterid birds. Ksepka has traveled to South America and New Zealand to collect and study fossil penguins. He is the author of numerous scientific papers on penguin evolution as well as the science blog "March of the Fossil Penguins ."
