"Religion made incursions into the traditional domain of science with attempts to bring intelligent design into the biology classroom and to choke off human embryonic stem-cell research on religious grounds. Scientists responded with counterincursions. Experts from the hard sciences, like evolutionary biology and cognitive neuroscience, joined anthropologists and psychologists in the study of religion, making God an object of scientific inquiry.""
