Earlier than thought files: Ancient and well-travelled worm

At ScienceDaily we learn that “New Evidence Shows Mobile Animals Could Have Evolved Much Earlier Than Previously Thought” (May 18, 2011): A University of Alberta-led research team has discovered that billions of years before life [animals?] evolved in the oceans, thin layers of microbial matter in shallow water produced enough oxygen to support tiny, mobile Read More…

Earlier than thought: Freshwater animals

Freshwater animals have been found at 435 million years ago, and were assumed to come later than saltwater ones. But “Come On In, the Water’s Fresh”, cries Sid Perkins at Science (17 May 2011): Tiny burrows. A dense aggregation of U-shaped fossil burrows in 520-million- to 542-million-year-old rocks pushes back the appearance of freshwater ecosystems Read More…

The Cambrian explosion: Getting past the Darwin lobby to look at the facts

Or anyway, the latest attempt at it. The Darwin lobby promotes uniformitarianism (long, slow gradual change caused by natural selection acting on random mutation), which is at odds with the evidence of rapid bouts of change followed by long periods of stasis. Over at Access Research Network, David Tyler discusses “The unscientific hegemony of uniformitarianism” Read More…

Dinosaurs from birds?

How well neoDarwinian evolution is established and the universal “consensus” over it is demonstrated by: Bird-from-Dinosaur Theory of Evolution Challenged: Was It the Other Way Around? ScienceDaily (Feb. 10, 2010) — A new study just published in the Proceedings of the National Academy of Sciences provides yet more evidence that birds did not descend from Read More…

California Lawmaker demands answers over museum censorship

Apparently round two of the controversy over the California’s Science Center’s cancellation of Darwin’s Dilemma is getting ready to take place. This was reported and discussed here back in October, as well as here and here in December. Now, a California State Senator is calling the constitutionality of the censorship into question.

Editing the Tape of Evolutionary History Yet Again

The late Stephen J. Gould once wrote “Replay the tape [of evolution] a million times from a Burgess [the Burgess Shale fossils]beginning, and I doubt that anything like Homo sapiens would ever evolve again. It is, indeed, a wonderful life.” (Gould, Stephen J. [Professor of Zoology and Geology, Harvard University], “Wonderful Life: The Burgess Shale Read More…
