Researcher: The huge dorsal carapace might have functioned like a plough,” Caron said.
One reason that Cambrian cephalopods would be very interesting is that the octopus and cuttlefish, apart from being quite complex, are some of the few invertebrates known to be seriously intelligent. Were their ancestors intelligent back then?
From the paper’s media release: Moreover, the scientists’ data series reveal that the development of the fauna took place within a very short period. The transition from the “Ediacara biota” – multi-celled but very simply organisms – to the diverse Cambrian life forms occurred over less than 410,000 years.
How this finding situates trilobites “more securely in between older arthropods … and crustaceans” is unclear. Apparently, crustaceans don’t breathe through their legs. Did the older arthropods breathe through THEIR legs? In any event, this find implies that the crustaceans underwent a dramatic switch in breathing mechanics, of which we apparently don’t have an account. How could we? We only found out about what the trilobites do very recently.
Battson: With regard to the sudden explosion of new body plans in the Cambrian, even Richard Dawkins admitted, “It is as though the fossils were planted there without any evolutionary history.”
Klinghoffer: Dr. Bechly recently penned a blockbuster 14-part series debunking Kimberella as a solution to the Cambrian Explosion. In case you missed it, it is a monumental, and morally important, piece of scholarship. The Cambrian event, a massive saltation, remains an unsolvable mystery for Darwinists, with all that implies about the evidence for purpose and design.
It’s probably going to take a while to pound the real story out of a lot of situations. Not much help to be expected from the fossils in the science bureaucracy.
Okay, but wait. Just because it would benefit a life form to have sophisticated eyes does not mean that it can just start growing them. That’s where Darwinism begins to shade into magic. There’s a missing factor here: How, exactly, were the prey life forms enabled to participate in the complex business of producing vision in response to the predator’s vision?
One can talk about the cichlid “burst” that lasted ten million years but now, the term “explosion” has become politically incorrect usage to describe the Cambrian because shut up.
Sorry, guys. The Cambrian is a bit like quantum theory. Anyone who ISN’T flummoxed by it doesn’t understand it. Now comes the punch line: “We suggest, as an alternative to “Cambrian explosion,” the Great Cambrian Biodiversification (GCB)…” Sure, that’ll catch on. It sounds like a large animal vet’s description of an elephant’s bowel problems.
This find, if it checks out, leaves more time for the evolution of algae but less for the evolution of animals. Which returns the Cambrian explosion to its “remarkable” status.
This “revolutionary animal” is not that much like the Cambrian creatures so far found but the big question is, how did life explode so quickly if it was only by chance? Why not just give up on that idea and study the creature for what it is?
Paper: “The genetic factors of bilaterian evolution,” has found that 157 new genes were required during the Cambrian explosion to account for the origin of bilaterians (animals with bilateral symmetry)
Researchers: “The genetic mechanisms underlying these events are unknown, leaving a fundamental question in evolutionary biology unanswered.” and “Contradicting the current view, our study reveals that genes with bilaterian origin are robustly associated with key features in extant bilaterians, suggesting a causal relationship.” = the genes originated with the bilaterians (creatures with two distinct sides).
The importance of the controversy that is said to be settled now does not seem nearly as great as the significance of the Cambrian explosion itself.
