(ASBMB screws up their description of evolution but at least their heart's in the right place.)

Unless they understand evolution, students can't really understand why some parts of a protein are the same in all species and other parts are quite variable. They certainly can't understand why you can construct a phylogenetic tree from sequences and why this tree closely resembles those trees made from comparing anatomy/embryology.
