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.
Somebody should invent software for them, maybe called ExcusePro. They just need to set the app to Cambrian Explosion and AI will come up with thousands of excuses in a split second.l They can just keep peeling them off, as needed.
Paleontologist Gunter Bechly looks at the claim that the Cambrian animals evolved from a long train of ancestors who somehow all just disappeared without a trace and finds it, well, unconvincing:
Curiously, researchers are pretty sure it was a parasite but what it is, apart from that, remains elusive. It’s an unusual case of knowing more about the organism’s behavior than about the organism itself.
A new study is out trying to find the LUCA (Last Universal Common Ancestor). Needless to say, things got even worse for those who place their belief in Darwinian thinking. Because the Concluding Remarks section is so devastating, I’m blockquoting the whole thing: Our work furnishes a new variable for the assessment of protein family Read More…
From 518 million years ago: The remains document the Cambrian explosion, a rapid flourishing of life-forms, and include many organisms never seen before — even at the most famous Cambrian fossil site, Canada’s Burgess Shale Carolyn Gramling, “Science News’ favorite fossils of 2019” at Science News So even more fossils just popped into existence, just Read More…
Had to happen eventually. And when a Cambrian arthropod brain turns up that can be analyzed, if it turns out to be pretty much like a modern arthropod brain, what reasonable conclusion should we draw about the design of life or the alleged lack thereof?
The Ediacaran creatures are fascinating predecessors to be sure. They will likely turn out to be explosions of life, just like the Cambrian, but often not clearly related to it.
Researcher: “Evidence is converging towards picturing the Cambrian explosion as even swifter than what we thought,” says Aria. “Finding a fossil site like the Burgess Shale at the very beginning of the Cambrian would be like looking into the eye of the cyclone.”
The claim that the worm challenges the Cambrian explosion which followed this Ediacaran period is weird because we knew there were worms in the Ediacaran on account of the tracks (and comb jellies too) but the explosion of multi-faceted life in the Cambrian is a unique event in any case.
For some years, it has not been the practice of many Catholics to question Darwinism. Most got sucked years ago into some muddle according to which the great theologian Thomas Aquinas didn’t supposedly think there could be such a thing as observable design in nature because that would make God a “tinkerer.” Some tinker. Anyway, Read More…
The Cambrian Explosion, demonstrated time and again to be an ‘explosion,’ is a problem for Darwinian theory. Darwin postulated gradualsim; in fact, he insisted upon it when pressed by supporters to modulate this position of his. The problem is that multiple life forms are required to “build” new life forms. You need lots of species Read More…
