- The Cambrian explosion or Cambrian radiation was an event that happened approximately 541 million years ago in the Cambrian period when practically all major animal phyla started appearing in the fossil record12345. It lasted for about 13 – 25 million years and resulted in the divergence of most modern metazoan phyla1. The event was characterized by the appearance of many of the major phyla (between 20 and 35) that make up modern animal life2.了解详细信息：✕以上信息汇总借助人工智能技术，若访问原文请查看了解详细信息。
