Evolution

Oldest (so far) cephalopods discovered at 522 million years old?

Wait a minute. Many cephalopods (octopuses, squid, and cuttlefish) are considered very intelligent though it is unclear how they got to be so. So, not only is this another instance of stasis (complex life forms emerge early and remain complex) but there is a real possibility that a high level of intelligence emerged early. Assuming that any intelligence at all could originate via a Darwinian mechanism, early origin followed by stasis does not sound like a Darwinian program for intelligence. Read More ›

Grand Darwinian experiment with 10,000 generations of yeast proves that Mike Behe is right

If the authors could have predicted adaptation through loss-of-function mutations, why didn’t they let high school textbook authors and pop science presenters in on the secret?: Michael Behe is right: Darwin devolves. Evolution is mostly about devolution. Does that maybe make sense in a universe where entropy is growing? But where does it leave Darwin? At the bus stop after the last bus has left? Read More ›

A forthright admission of how the lamprey larvae change official vertebrate history

Lamprey paper first author: “Once fortified with historical inertia, just-so stories are difficult to interrogate.” Just-So stories in science are not just difficult to interrogate but risky! People fear the questioner Doubts the Narrative and That Is Not Allowed. The essay is charming and it is heartening to read someone in science who is prepared to let evidence, not Narrative, be the guide. Read More ›

Researchers: Lamprey larvae do NOT resemble the early animal “that all vertebrates evolved from”

The resemblance sounds like so nice and neat a Darwinian belief that few can have wanted, in these times, to subject it to scrutiny. But some people did. And it’s almost like they don’t mind rewriting the textbooks. It’s as if they don’t “trust science” or something. Read More ›

At Oscillations: Cytogeneticist Antonio Lima-de-Faria torches obscurantism in science in new book, Suzan Mazur reports

He was an early non-Darwinian evolutionist (1988 is pretty early), mainly a structuralist. He continues to publish books at nearly 100 years of age. Read More ›

Eric Holloway: Is AI the next stage of evolution?

Holloway: The complex organization of energy we humans see around us in our verdant fertile nest is enormously atypical. This fundamental law drives right through the heart of any technology, genetic or otherwise, that we might invent … Read More ›

Does evolution help us understand why some species in the same genus are significantly smarter than others?

One could simply say, “Evolving more intelligence helped the animal to survive.” The trouble with that explanation is, many free-roaming life forms would probably survive more readily if they were more intelligent. But they do not develop greater intelligence on that account. There must be more to the story. Read More ›

Claims for random evolution overlook the fact that life needs software as well as hardware

Richard W. Stevens points out that a bird does not fly just because it has wings; it needs a Explanations of the evolution of flight do not account for that.“flight” program in its brain. Read More ›

Researchers ask: Are we more like primitive fish than we thought?

“the genetic basis of air-breathing and limb movement was already established in our fish ancestor 50 million years earlier” than a transition to land. That sounds like directed evolution, no? The researchers have stumbled onto directed evolution but their careers depend on not recognizing that fact. Read More ›

Researchers: Huge coelacanth fish is “not a living fossil”

For all practical purposes, the coelacanth is a “living fossil,” in the sense that it is an example of stasis. It wanders a bit genetically over millions of years but doesn’t change much over hundreds of millions of years. Could we say the same of most vertebrates? Read More ›

Higher mutation rates in non-double helix DNA create intriguing alternative to common ancestry

Researcher: "But it's possible that the mutation rate is so high in some of these non-B DNA regions that the same mutation could occur independently in several different individuals. If this is true, it would change how we think about evolution." Read More ›
