When used properly, homology can be not only a useful tool, but predictive. For example, Dmitri Mendeleev made the Periodic Table of the Elements in 1869 and was able to predict later discoveries of elements. Mayhaps biblical creationists will be predicting trait distribution among critters.
If God made people as people, why are we full of “animal parts”? Look at your arm for a moment and try to picture the bones inside. There’s one bone attached to the body, two bones in the forearm, a little group of wrist bones, and bones that extend out into the fingers. As it turns out, there are many other living things that have forelimbs with a similar pattern: the foreleg of a horse or dog, the wing of a bat, and the flipper of a penguin, for example, as shown in Figure 6. Biologists use the term “homology” for such similarities in basic structure.To learn more, click on "Comparative Similarities: Homology"
