could be used to construct a family tree of hemoglobin and myoglo-
bin variation among organisms. This tree agreed completely with
observations derived from paleontology and anatomy about the
common descent of the corresponding organisms.
Similar family histories have been obtained from the three-dimen-
sional structures and amino acid sequences of other proteins, such
as cytochrome c (a protein engaged in energy transfer) and the di-
gestive proteins trypsin and chymotrypsin. The examination of
molecular structure offers a new and extremely powerful tool for
studying evolutionary relationships. (Science and Creationism, p.18)
It is astonishing that the NAS should make such a claim, ignor-
ing important research and findings in this area. In actuality, compar-
isons of the molecules cited by the NAS actually represent enormous
The so-called family trees obtained from analyses of such molecules as hemoglobin,
myoglobin, and cytochrome c conflict both with one another and with other data.
