Steve Meyer addressed this topic extensively in Chapters 2, 3, and 4 of Darwin’s Doubt, and Figure 2.5 in his book is a thoroughly researched and conservatively argued take on exactly how many animal phyla predate the Cambrian period and how explosive the Cambrian explosion was. Response: “ How ‘Sudden’ Was the Cambrian Explosion? Nick Matzke Misreads Stephen Meyer and the Paleontological Literature New Yorker Recycles Misrepresentation”Ĭlaim: “There was complex animal life before the Cambrian so it does not represent the origin of many types of animals.” But they are very common objections and so we compiled this FAQ to help address common misconceptions about the Cambrian explosion.Ĭlaim: “The Cambrian Explosion was not a geologically short event but really took millions of years.
The points made below by our friend’s interlocutor are simplistic and don’t reflect what leading Cambrian experts really think. This made it very easy to defend his arguments, which we’ve done across numerous articles here on Evolution News. Stephen Meyer addressed these points in detail in Darwin’s Doubt with thoroughly researched arguments well backed by the scientific literature. He was engaged with an interlocutor was making all kinds of contradictory “throw everything at the wall and see what sticks” objections that were simply factually inaccurate and are belied by mainstream scientific experts.
