Quizplus · Accepted Answer

The Cambrian explosion is a period around 542 million years ago when there was a rapid diversification of multicellular animal life on Earth. This event led to the emergence of many new body plans, which eventually gave rise to the vast variety of animal life we see today. Although some simple multicellular organisms existed before the Cambrian explosion, it was during this period that the first large, complex, and diverse groups of animals appeared, including arthropods, brachiopods, echinoderms, mollusks, and chordates.
