Gallup released a poll, that coincides with Darwin's birthday, which examines American's belief in biological evolution. It is a great poll, breaking down belief patterns across education attainment, age , religiousness, etc.
However, several reports and blogs about this poll disparage Americans for their lack of scientific sophistication, but I think that the results are far more positive then I would have guessed. Only 25% outright deny evolution! I would have thought a clear majority would take this stance as was shown in 2005. A further 36% do not have an opinion, and as scientists and educators, these folks are the reason why we educate and hold events like Darwin Day. Thank you to all those who work so tirelessly promoting science education and literacy, like those at NCSE.
