Milking the Martian Meteorite

One would think everything has been told about ALH 84001, the Martian meteorite that made a splash in 1996 with claims it contained fossils of living organisms.  That claim was essentially discarded in subsequent years.  Its major contribution was giving life to a new science called astrobiology and energizing NASA’s Mars program.  Now, a new […]

Emergence of Genetic Code Touted

Most origin-of-life researchers have acknowledged the extreme improbability of the genetic code arising by chance.  Their approaches to get around this problem have varied considerably since the Miller experiment succeeded in generating a few amino acids.  Despite the celebrations that 1953 experiment generated (05/02/2003), it did not even begin to approach the problem of solving […]

How the Girl Evolved Fear of Spiders

Today’s Evolutionary Just-So Story is brought to you by New Scientist: “Girls Are Primed to Fear Spiders.”  Once upon a time, while cavemen were out hunting and gathering, the women back home had to learn to avoid dangerous animals.  David Rakison of Carnegie Mellon University put this all into evolutionary terms for the rest of […]

Does Evolution Produce Winners?

Referees at UCLA are calling the shots in an unusual sport: the evolution game.  Mammals, birds and fish swept the medals.  The losers?  crocodiles, alligators, and a “living fossil” reptile called the tuatara.  According to the judges, the more the biodiversity, the more a group wins points; the more their species go extinct or remain […]

Evolution 2.0: What’s in the Upgrade?

Consider Evolution 1.0.  That was the old biological, Darwinian stuff.  Now, there’s Evolution 2.0 – the evolution of technology.  W. Brian Arthur explained the upgrade package for New Scientist: “On the origin of technologies.”     Arthur is not the first to try to define a law of nature for the origin of technology.  He […]

Twitter the ET Bandwidth Wagon

If you have nothing better to do, send a message to an alien.  Leonard David reported on Space.com that a website in Australia is collecting messages to beam up to a planet named Gliese 581d that is 20.3 light-years away.  Even a Senator who is Australia’s Minister for Innovation, Industry, Science and Research got involved.  […]

Fire Technology Began Much Earlier Than Believed

A team publishing in Science1 claims they found evidence that humans were using fire treatment of stone tools much, much, much earlier than prior dates for cognitive abilities.  But they can’t seem to settle on just how early.  The dates vary by more than 100%.  One date, 72,000 years before the present, is about 50,000 […]

Evolution of the Knuckle Head

An evolutionary anthropologist looked at the knuckles of chimpanzees.  Then she looked at the knuckles of gorillas.  Then she looked at her own knuckles.  Conclusion: humans evolved from tree climbers, not knuckle walkers.  Her theory can be read in Live Science, based on a paper in PNAS.1     Tracy Kivell and Daniel Schmitt from […]

Did Evolution Create Genetic Proofreading?

Protein manufacture in the cell is such a critical operation, there are numerous error-checking mechanisms the cell uses to get it right.  One of the most amazing is the careful association of DNA codons with amino acids, and the “proofreading” or “spell checking” that ensures fidelity.  How could spell checking evolve?     Science Daily […]

Does Evolution Need a Helping Hand?

New Scientist didn’t think about that question, because reporter Ewen Galloway he said, “If humans want to persuade microbes to produce vast quantities of fuels or pharmaceuticals, we may need to give evolution a helping hand.”     His article was about researchers at Harvard Medical School using computers to do “rapid evolution.”  How this […]

Evolution’s Guiding Hand Is Far From Obvious

A recent example of applying evolutionism to everything was seen on Science Daily and PhysOrg last week.  Some psychologists are telling us that evolution taught us to take turns.  “It’s not just good manners to wait your turn — it’s actually down to evolution, according to new research by University of Leicester psychologists.”     […]

Aliens Are Not Bodybuilders

Seth Shostak of the SETI Institute is willing to bet “dollars to Devil Dogs that any extraterrestrials we detect won’t be muscular guys with deep voices and corrugated foreheads, or even big-eyed, hairless grays.”  It all has to do with the way evolution works.     In the weekly SETI column for Space.com, Shostak opined […]

Stretching Out the Cambrian Explosion

“Dawn of the animals: Solving Darwin’s dilemma” is the confident-sounding title of an article about the Cambrian explosion in New Scientist.  Their solution, however, did not include finding transitional forms.  It revolved around “setting the stage” environmentally for the sudden appearance of complex animals.     Reporters Douglas Fox and Michael Le Page began by […]

Lightning Cooks Up Weird Science

Get a charge out of this headline from New Scientist.  A couple of scientists from University of Arizona studied fulgurites, the structures formed in sand by lightning strikes.  They found that they contain phosphites (oxidized phosphate molecules).  They theorized that lightning strikes could have provided phosphites which the primordial soup used to build RNA and […]

Origin-of-Life Researchers Caught Playing With Toys

A “virtual primordial soup” cooks up life in a computer program in a “toy universe,” according to reporter Leslie Mullen at Space.com.  She wrote, “The power of computer processing could one day solve the riddle of life’s origin.”     EvoGrid is “a computer creation concept that would be a digital version of the primordial […]
