Common Anscestors

Lampreys, a primitive fish with a jawless sucking mouth with rasping teeth, and humans shared their last common ancestor some 560 million years ago. Even so, biologists from the California Institute of Technology have discovered that the SoxE family of genes is involved in the facial development of lampreys, just as SoxE is responsible for formation of the human pharynx and parts of the jaw.

Intelligent design "theorists" and their country cousins, creation "scientists," by and large don't accept common ancestry, but this is something they may just have to face up to.
