But perhaps the most serious medical consequence of our bipedal evolution is that changes in the pelvis required for bipedalism make childbirth very difficult.
Another new, and increasingly common, objection of creationists to evolution is that evolutionary mechanisms such as mutation cannot generate new information.
A fascinating outcome of directed evolution is that new insights into mechanistic enzymology can be gained.
A central tenet of evolution is that unnecessary genes become non-functional due to random mutation.
As Uno pointed out, major science education reform movements all emphasize the need to organize around major themes and core concepts and "for biology, evolution is that".
An illustration of their rapid evolution is that CENP-A proteins from even closely related species of Drosophila fail to function when heterologously expressed in another species.
Indeed, one of the growing realizations about protein evolution is that mutations that spread by neutral genetic drift may still have an impact on future evolution [ 24, 25].
The hallmark of concerted evolution is that high sequence similarity between genes is maintained within a species (between paralogues) while divergence occurs between species (between orthologues).
The thing about evolution is that it takes a generation.
The biggest frustration in "Evolution" is that it squanders an interesting premise.
The second reason for teaching evolution is that the subject is immediately relevant here and now.
