I don't think we nec understand the creation story in the Bible as written, so the ideas in evolution aren't a hot button issue for me. I just honestly think that we have people who are literally trying to supress any other viewpoint. Where is the diversity?
Biology class is for biology. Students should be taught science. Scientific theories make testable predictions about the world we live in. Science helps us understand our natural world as it is. Scientists use science to understand biology and disease, develop new treatments and to predict where the natural world is headed. In schools, students should be trained in scientific thinking to participate in this endeavor.
Understanding evolution is fundamental to science. Why do bacteria develop resistance to antibiotics? Why do viruses affect some species but not others? Why does sickle cell trait reduce likelihood of malaria infection and therefore become a selected trait?
Belief in a creator does not constitute scientific thinking and will not help solve biological problems in the world we inhabit. I have no objection to teaching creationism or ID or alien origins or ghosts or exorcism or any other fantastical explanation of the world- in homes, in church, or in a private retreat.
But please leave science classes to science.
There was plenty of speculation in our biology curriculum.
Understanding evolution is NOT fundamental to SCIENCE. There are many areas of science where evolution never even comes into play. Understanding the scientific method is fundamental to science and can be applied to the ToE but the ToE is not required to practice other branches of science.
