Philadelphia has always been a scientific city, from Benjamin Franklin's discovery of electricity to the present day.

So to celebrate Charles Darwin's 200th birthday in 2009, The University of Pennsylvania Museum of Archaeology and Anthropology presents Surviving: The Body of Evidence, a new, interactive exhibit that explores the process of evolution and its profound impact on the way we live and think.

Start your exploring at "Fit for Life," an introduction to your inherited human strengths and capabilities.

Then travel back millions of years to meet ancestors from now-extinct species, as you consider "Our Place in the Natural World."

And finally, touch and examine more than 100 casts of fossils as you move forward with "Finding Our Human Ancestors."

Surviving kicks off The Year of Evolution, which includes a full year of evolutionary events. Happy birthday, Charles Darwin!
