Misconceptions about Random Genetic Drift

Genetic Drift

Evolutionary change that occurs by random sampling of different alleles from one generation to the next. This causes nonadaptive evolutionary change.

"Why Evolution Is True"There seem to be two important themes in the current pedagogical literature on science education. One of them is about student-centered learning—a concept I think we should all adopt. The other is about student misconceptions and how to deal with them. Much of the literature suggests that misconceptions need to be confronted and corrected. They can't be corrected by simply presenting the "correct" information. You need to actually address the misconception and show why it is wrong. This is a form of "teach the controversy" and that's not going to sit well with many American supporters of evolution.

Here's an interesting paper on "Biology Undergraduates’ Misconceptions about Genetic Drift" (Andrews et al., 2012). The abstract covers all the important points. Read more »
