Trilobites look up silently from their Burgess Shale rock slabs, with sad eyes, asking, “Where did I come from?”
True arthropods are among the most sophisticated animals that appeared without ancestors in the Cambrian explosion.
Many claim the Cambrian explosion was triggered by a sudden global increase in oxygen levels.
The top-down pattern of appearance of animal phyla during the Cambrian explosion represents major conflicting evidence for Darwinian evolution.
