Mistaken identity

I have been mistaken for someone who knows a lot about Darwin and the Origin (this happens a lot), and so have been invited to speak on these topics at the next meeting of Nature Calgary (aka the Calgary Field Naturalists' Society). The talk is on May 20 at 7:30 pm at Ft. Calgary. Apparently the meetings are open to the public if you want to come along. But if you'd rather not spend an evening listening to an illustrated synopsis of the class you've just taken, you may want to give it a miss.
