A new poll is out on public opinion on the origin of human life. See Science and Nature for June 17-21, 2004 (the link includes various polls on scienctific issues, in reverse chronological order).
I like how Mahablog put it, noting the obvious confusion that Americans express on the topic that seems (to them) to pit emphirical evidence against religion (hmm, wonder where they got that idea???):
Maybe this is telling us that many people sorta kinda believe that man evolved but are afraid they will be struck by lightning if they deny God, even to a pollster.
