The Demise of Another Evolutionary Link: Archaeopteryx Falls From Its Perch
A few days ago we saw Ida fall from her overhyped status as an ancestor of humans. Now some scientists are claiming that Archaeopteryx should lose its status as an ancestor of modern birds. Calling Archaeopteryx an “icon of evolution,” the Wall Street Journal (WSJ) borrows a term from Jonathan Wells while reporting that “[t]he feathered creature called archaeopteryx, easily the world’s most famous fossil remains, had been considered the first bird since Charles Darwin’s day. When researchers put its celebrity bones under the microscope recently, though, they discovered that this icon of evolution might not have been a bird at all.” According to the new research, inferences about growth rates made from studies of Archaeopteryx‘s ancient fossilized bones show Read More ›
The Evolution of “Ida”: Darwinius masillae Fossil Downgraded From Ancestor to Pet
A few months ago, “Ida” was sitting on top of the world. She’d been lauded as the “eighth wonder of the world” whose “impact on the world of palaeontology” would be like “an asteroid falling down to Earth.” Falling, indeed. On October 21, Nature published an article announcing that “[a] 37-million-year-old fossil primate from Egypt, described today in Nature, moves a controversial German fossil known as Ida out of the human lineage.” Wired also published a story, noting that, “[f]ar from spawning the ancestors of humans, the 47 million-year-old Darwinius seems merely to have gone extinct, leaving no descendants,” further quoting a paleontologist calling Ida “a third cousin twice removed … only very distantly related to living and fossil anthropoids.” Read More ›
Experimental Data Force Researchers to Admit There’s “No Such Thing As Junk RNA”
Originally, proponents of neo-Darwinian evolution lauded “junk” DNA as functionless genetic garbage that showed life is the result of blind and random mutational events. Then “junk” DNA was disproved by the discovery that the vast majority of DNA is being transcribed into RNA. Did the failure of this Darwinian assumption cause evolutionists to terminate their love affair with biological “junk”? Of course not. They just shifted their argument back, claiming that the cell is full of “junk RNA”–DNA that is being transcribed into RNA but still does nothing in the cell. Earlier this year we reported on a Nature paper suggesting function for “junk” RNA. Now a Science Daily NewsArticle is confirming that finding. Aptly titled “No Such Thing As Read More ›
Controversial New Collection Highlights Berlinski’s Dismantling of the Facade of Scientific Overconfidence
What do Discover magazine, The London Gazette, The Wichita Eagle, Commentary, Forbes, The Weekly Standard and UC Berkeley’s student paper, The Daily Californian, all have in common? They are just some of the publications that have published an essay or opinion piece by David Berlinski in the past 15 years. And those pieces are among 32 of Berlinski’s finest finally collected together in one volume: The Deniable Darwin. Berlinski, there is little argument, is a skeptic’s skeptic — the last of a dying breed. Lately it seems that everywhere one looks there is someone with the answer to everything. There are precious few true skeptics left, and Berlinski is certainly in the top rank in regards to the sciences. When Read More ›
New Work by Richard Lenski
A new paper from Richard Lenski’s group has appeared in Nature and has garnered a fair amount of press attention. Some people asked me for my thoughts about it. The new paper continues the grand experiment that Lenski has been publishing about lo these many years — allowing a culture of the bacterium E. coli to continuously grow and evolve under his close observation. The only really new thing reported is a technical improvement — these days one can have the entire genome of E. coli “re-sequenced” (that is, determine the sequence of the entire DNA of the particular E. coli you’re working with) done for an affordable cost. (There are companies which will do it for a fee.) So Read More ›
