Amniotes evolved ~340 million years ago, but the oldest known fossilized amniote eggs are from the Late Triassic, over 200 million years later. Preservation probably played a large role in the hiatus between evolution and preservation, as some kinds of eggshell are more easily fossilized than others.The fossil record cannot accurately determine when one species becomes another species. However, two hypotheses regarding speciation also exist. Phyletic speciation suggests that abrupt mutations in a few regulatory genes occur after a species has existed for a long period of time. This mutation results in the entire species shifting to … Fossils help us to learn about how ancient organisms interacted with their environments and with one another.
