Fossils and Time
Fossils serve as crucial records of past organisms, revealing significant changes in biodiversity over geological time. As we dig deeper into sedimentary layers, a clear trend emerges: older rocks contain simpler, less diverse organisms, while younger strata showcase a rich variety of complex life forms. Despite interruptions from mass extinctions, the fossil record illustrates a compelling narrative of evolving animal forms through the ages.In this clip
