There is a new Gallup poll surveying American's belief in evolution. The bad news is that 40% of Americans believe that God created humans in their present form within the last 10,000 years. The good news is that the percentage of people who believe this has fallen to its lowest level since the first such survey in 1982. Also the pace of decline seems more rapid since the year 2000.
