AUSTIN — The verdict from Texas scientists is nearly unanimous: 98 percent favor the unadulterated teaching of evolution in public school classrooms, according to a report released Monday as the State Board of Education prepares to weigh in on the controversy. A vast majority of the scientists say students would be harmed if the state requires the teaching of the "weaknesses" of evolution, according to the survey conducted for the Texas Freedom Network Education Fund, an organization that works on issues involving religious freedom, civil liberties and public education.
