A new study published in Science this week shows that, although "anti-science" approaches like creationism have been removed from most classrooms in the US, they still influence the way some teachers teach evolution, says 80beats' Andrew Moseman. Through a survey sent to high school science teachers, two researchers from Pennsylvania State University found that 28 percent of the 926 respondents "unabashedly" taught evolution to their students, Moseman says. About 60 percent of biology teachers belonged in the "cautious" category, as "neither strong advocates for evolutionary biology nor explicit endorsers of nonscientific alternatives," according to the study.
