Tony: Yes. DNA is the code, and epigenetic changes are the various outputs that change depending on environmental inputs and are inheritable without rewriting the underlying program.

DHW: We observe gaps, not root types appearing out of nowhere! Punctuated equilibrium means long periods of stasis, broken by sudden bursts of creative activity. Nothing to do with out-of-nowhere. I can’t solve the Cambrian mystery any more than you can, but here is a website with answers you will reject and evolutionists will accept, both of you because of “confirmation bias”. Nobody knows the truth.

Does the Cambrian Explosion pose a challenge to evolution?

QUOTE: “Scientists are now gaining a better understanding of what existed before the Cambrian Explosion as a result of new fossil discoveries. […] Some of the new fossil discoveries, in fact, appear to be more primitive precursors of the later Cambrian body plans. The discovery of such precursors shows that the Cambrian organisms did not appear from thin air.”

TONY: But do they have precursors or are the new forms that did not exist prior to the Cambrian?

DHW: The quote says they did have “more primitive precursors”.

Tony: Within the cambrian, but it doesn't state if there were pre-cambrian precursors.

You are correct. I don't accept the wording of the website. The recent Ediacarans from China were so strange they were thought originally to be plants and only recently have been accepted as animals. My entry: Friday, August 10, 2018, 20:16
