DENVER (AP) — Democrats rejected a Republican lawmaker’s idea Monday urging schools and colleges to create a friendly environment to discuss what he considers controversial science issues, a move that opponents feared would lead to debates about creationism and evolution.

The proposal called on public schools and colleges to create an environment for students to encourage scientific questioning on “controversial issues in science education.” Rep. Stephen Humphrey, R-Severance, said he recognized the concerns from opponents that the bill would open debate on religious teachings, but he insisted that’s not what his proposal would do.
