Researchers: Ediacaran to Cambrian transition took “less than 410,000 years”

Even if these researchers are a teensy bit optimistic about their pinpoint accuracy, the pattern is clear: The history of life is becoming a field markedly less favorable to hand-waving. And note, in 410,000 years, the transition from the multicellular but simple Ediacaran life forms to the diverse Cambrian life forms is supposed to have taken place purely by natural selection acting on random mutation (Darwinism). Aw, come on.

Researchers: Extreme fluctuations in oxygen levels, not gradual rise, sparked Cambrian explosion

Explanations of the dramatic Cambrian explosion of life forms (540 million years ago) are a cottage industry, with arguments about oxygen a staple of the discussion. See, for example, Maverick theory: Cambrian animals remade the environment by generating oxygen Did a low oxygen level delay complex life on Earth? There was only a small oxygen […]

Odd tube-shaped animal appears, disappears in Cambrian

From ScienceDaily: The creature belongs to an obscure and mysterious group of animals known as the chancelloriids, and scientists are unclear about where they fit in the tree of life. They represent a lineage of spiny tube-shaped animals that arose during the Cambrian evolutionary “explosion” but went extinct soon afterwards. In some ways they resemble […]

Panspermia (maybe life came from outer space) is back, in Progress in Biophysics and Molecular Biology

Abstract: We review the salient evidence consistent with or predicted by the Hoyle-Wickramasinghe (H-W) thesis of Cometary (Cosmic) Biology. Much of this physical and biological evidence is multifactorial. One particular focus are the recent studies which date the emergence of the complex retroviruses of vertebrate lines at or just before the Cambrian Explosion of ∼500 Ma. […]

Michael Medved discusses intelligent design theory with Darwin’s Doubt author Steve Meyer

 Darwin’s Doubt deals with the Cambrian explosion of life forms about 550 million years ago. Philip Cunningham, who forwarded this link, notes, Stephen Meyer joins Michael to discuss the origins of life and the biology’s big bang, the Cambrian explosion. Animal forms come and go, but what links them as “acts of mind” (as […]

Well, of course, animal behavior IS an argument against Darwinian gradualism

Remember Gunter Bechly, the paleontologist who got erased from Wikipedia *? At ENST, he says, Based on the Darwinian narrative, we should expect not only that morphological complexity increases gradually in the fossil record, but we should also expect the same for complex animal behavior. This is because according to Darwinists, “Evolution not only is […]

Researchers: Animals’ “agronomic revolution” earlier than thought

From ScienceDaily: In the history of life on Earth, a dramatic and revolutionary change in the nature of the sea floor occurred in the early Cambrian (541–485 million years ago): the “agronomic revolution.” This phenomenon was coupled with the diversification of marine animals that could burrow into seafloor sediments. Previously, the sea floor was covered […]

Maverick theory: Cambrian animals remade the environment by generating oxygen

From Jordana Cepelewicz at Quanta: For decades, researchers have commonly assumed that higher oxygen levels led to the sudden diversification of animal life 540 million years ago. But one iconoclast argues the opposite: that new animal behaviors raised oxygen levels and remade the environment. … n a paper published in the January issue of Geobiology, […]

Secrets of 520 million-year-old brain debated, raise conundrums

From Andrew Urevig at National Geogaphic: Contradicting some previous accounts, the team argues that this new evidence appears to show that the common ancestor of all panarthropods did not have a complex three-part brain—and neither did the common ancestor of invertebrate panarthropods and vertebrates. … That structure can be traced back through the fossil record.

Cambrian fossil shows parent caring for young

From Jasmin Fox Skelly at New Scientist: A 520-million-year-old fossil shows an ancient shrimp-like creature caring for its four offspring. It is the oldest ever example of a parent actively looking after its young after they hatch. More. (paywall) The arthropod may be the ancestor of insects and spiders (or maybe not). We have one “snapshot” […]

The cancer theory of the Cambrian explosion of life 541 million years ago

No really. From Evolution News: You thought you’d heard it all? All the desperate materialist theories seeking to explain the burst of biological novelty some 530 million years ago that Meyer writes about in Darwin’s Doubt? You were wrong. Along comes Lund University in Sweden with a “Novel hypothesis on why animals diversified on Earth.” […]

Complex worm find from Cambrian (541-485 mya) “helps rewrite” our understanding of annelid head evolution

From ScienceDaily: Researchers at the Royal Ontario Museum and the University of Toronto have described an exceptionally well-preserved new fossil species of bristle worm called Kootenayscolex barbarensis. Discovered from the 508-million-year-old Marble Canyon fossil site in the Burgess Shale in Kootenay National Park, British Columbia, the new species helps rewrite our understanding of the origin […]
