Question

Quizplus · Accepted Answer

The Cambrian explosion refers to the rapid diversification of animal life that occurred approximately 530 million years ago, during which many major animal phyla first appeared in the fossil record. The movement of animals onto land occurred much later in evolutionary history, during the Devonian period, and is not directly related to the Cambrian explosion. On the other hand, factors such as predator-prey relationships, atmospheric oxygen levels, and genetic changes likely played important roles in driving the diversification of animal life during the Cambrian. Of these factors, the least important is likely the emergence of predator-prey relationships, as it was probably a consequence of diversification rather than a driving force behind it.
