Researchers in Lund, Sweden have found that the waxy surface of the leaves of the Ginkgo tree are well preserved in fossil leaves, unlike the DNA which breaks down with age. Analysis of the biochemicals in the fossil leaves shows that they are the same as in their living counterparts. Since the chemicals are coded for by the DNA, these results show that the DNA has not changed over the years either. Living fossils such as the Ginkgo tree have reproduced according to their kind, with their seed (DNA) within themselves, as recorded in Genesis 1:12.
