Scientists call our time “the age of biology” because the biological sciences have witnessed such tremendous growth in the number and significance of scientific discoveries.
The most powerful discovery is biological evolution and its driving force of natural selection. (See the January issue 2009 of Scientific American).
Close behind is the discovery of the “molecule of life”, DNA, which is shared in different forms by all Earth’s organisms and which confirms evolution.
Yet in a 2007 study of 34 Western developed nations, the United States ranks next to last (above Turkey) in the proportion of its population accepting the validity of biological evolution.
