The propagation of misconceptions about the theory of biological evolution must be addressed whenever and wherever they are encountered. The recent article by Paz-y-Mino and Espinoza in this journal contained several such misconceptions, including: that biological evolution explains the origin of life, confusion between biological and cosmological evolution, and the use of the term “Darwinism,” all of which we address here. We argue that science educators, and biology educators particularly, must be aware of these (and other) misconceptions and work to remove them from their classrooms.
