The Cambrian is a poor choice since there were almost no fossils before it, so it is harder to find earlier forms to compare. But if we stick to well-known examples, I presume you have heard of Archaeopteryx. What do you think that is?There is little fossil evidence for changes of kinds. What pre Cambrian fossils show intermediates? Fossils like the Piltdown man are complex but are shown to be hoaxes.
Or Tiktaalik?
Or Pakicetus?
But actually the entire fossil record shows change occurring. Huge numbers of fossils have been mapped onto a phylogenetic tree and thereby related to their ancestors and descendants.
