Apparently some scientists have been studying evolution on a molecular level and have come to the conclusion that evolution is not reversible — it can’t go backwards. What that means is, they think we evolved from a common ancestor of apes, but our great-great-great-great-great grandchildren won’t evolve back into apes.
That’s a relief, isn’t it?
Creationists agree with this. Creationists believe in microevolution — small changes that take place within the boundaries of a “kind” so that there are Dobermans and German Shepherds and Poodles that all came from one dog ancestor. But they don’t believe in macroevolution — meaning that dogs will always give birth to more dogs, there won’t be a dog some day who gives birth to an ape.
Creationists also believe that any genetic mutations result in loss of genetic information. So Adam and Eve’s descendants have many different skin colors and facial features. But if you take two very dark skinned descendants of Adam and Eve and study their descendants, you probably won’t ever find a really light skinned one. Unless one of their descendants marries a light skinned person and the genes come from there. As time goes forward, we lose genetic information, we don’t gain it. So, we can’t go back. We might not ever see a dog that looks exactly like the original dog as God created him.
