In the Cambrian Explosion, numerous forms of highly complex animal life appeared suddenly in the rock record with absolutely no evolutionary precursors. At the time Darwin’s Origin was published in the 1800s, the lowest-most fossiliferous rock layer where complex life first appears—what we now call the Cambrian—was then known as the Silurian.

The Cambrian explosion has long been a basic research frontier that concerns many scientific fields. Here we discuss the cause-effect links of the Cambrian explosion on the basis of first
