A duplicative post, but in case you needed another reminder: If you want to hear me share my newly-gained knowledge of the Origin, I'll be giving a "guided tour" of the book to Nature Calgary (aka Calgary Field Naturalists' Society) at their monthly meeting in May. The event is free and open to the public.
"Darwin's Origin of Species: A Guided Tour"
Wed. May 20, 7:30 pm
Burnswest Theatre, Fort Calgary
