The fossil evidence  Fossils allow us a glimpse into the development of life on Earth. Fossils show a development from earlier, less complex forms of life, through to newer, more complex forms of life, with characteristics developed from earlier organisms. This progression is strong evidence for evolution. Since fossilization is a rare event, there are some gaps in the fossil record, but all the available evidence is consistent with, and fully explained by, evolution. [1]  There are many examples of transitional fossils, including of our own ancestors, showing how humans evolved from apelike creatures. For example, scientists discovered the skeleton of Ardipithecus ramidus, nicknamed “Ardi”. Ardi is the oldest fossil of a human ancestor, and the last common ancestor of humans and modern apes. Ardi shows a mixture of advanced characteristics and primitive traits. [2]  If fossils had been laid down by a catastrophe such as the Genesis flood, as Creationists argue, then complex and simple lifeforms should be mixed together, with no clear order or progression. But the fossil record shows a clear progression in complexity.
