One of the frequently asked questions on this program is ‘how’ and ‘why’ we are here. We asked it of two cosmologists recently and on this episode we discuss it in evolutionary terms with our friends Dr. Lance Grande of the Field Museum and Dr. Robert Richards of the University of Chicago’s Center for the History of Science and Medicine. Some fantastic questions were submitted to the panel from callers and emailers. Forever in pursuit of knowledge and truth is the crux of this show, and this is a program you will not want to miss. If yours is an inquiring mind, you’ll want to see Dr. Grande’s new book, The Lost World of Fossil Lake.
