Iowans have an opportunity to hear from a hero in the battle to halt or reverse climate change.

The event is the annual Iowa City Darwin Day, actually a two-day symposium to honor Charles Darwin, the naturalist whose book, “On the Origin of Species,” posited evolution as an explanation for the diversity of life on Earth. The celebration is held every year on or around the great scientist’s February 12 birthday. This year it’s Friday and Saturday, February 23-24, on the University of Iowa campus.
