Quote: Nearly all animal phyla* made their first appearance in the fossil record at essentially the same time, an interval of some 5 million years [ET**] (about 525 to 530 million years ago [ET**]) called the "Cambrian Explosion."51
Response: 1) This is outdated. The beginning of the Cambrian "explosion" has been dated to ~543 million years. And, this more accurate date for the base of the Cambrian has been known for more than 10 years!\n
