Cambrian Explosion
The Cambrian Explosion refers to a significant event approximately 541 million years ago when a remarkable diversity of life forms rapidly appeared in the fossil record. During this period, many major groups of animals emerged, including early ancestors of modern species. This explosion of biodiversity is notable because complex organisms with hard bodies began to flourish, leading to the development of various ecosystems. The Cambrian Explosion marks a pivotal moment in evolutionary history, as it set the stage for the complex life forms we see today, highlighting the rapid evolution and adaptation of early life on Earth.
