Some rock layers contain fossils that are found out of the supposed evolutionary order, i.e. older fossils on top of younger fossils. This is usually explained by a concept called “overthrusting.” In this process, rock layers break up and one section is uplifted. Forces push the one layer containing the older fossils over the top of the younger layers. In some cases, there seems to be evidence of this, and at other times there is absolutely no evidence. But we should find ample evidence if rock layers are sliding over the top of other layers. Perhaps in these cases, we have evidence that evolution really doesn’t have the answer?
