What Is Man?
November 5, 2009
Science often makes pronouncements about the human species.  We should be mindful of the worldview behind them.     Live Science published an article with the confident-sounding title, “Human Evolution: Where We Came From,” accompanied by the iconic sketch of Ardi (see 10/02/2009) and an obligatory reference to Darwin.  Even though reporter Charles Q. Choi, […]

Materialists: What Do You Know?
October 28, 2009
For people who brag about their work, scientists are an odd lot.  At one moment they are touting science as the surest path to knowledge and understanding.  The next moment it seems like they are at square one.  This is particularly true of materialist cosmologies and Darwinian theories for the origin and development of life.  […]

Modern Men Are Wimps
October 23, 2009
Whatever happened to survival of the fittest?  Our ancestors were much stronger, says the author of a new book on anthropology.  PhysOrg reported on a book by Peter McAllister that says today’s males don’t measure up physically to their counterparts even a century ago, let alone those in the Roman empire and earlier.     […]

Beethoven: It All Began With a Thump
October 17, 2009
Live Science in all seriousness, “When monkeys drum, they activate brain networks linked with communication, new findings that suggest a common origin of primate vocal and nonvocal communication systems and shed light on the origins of language and music.”     Choi reported on work at the Max Planck Institute for Biological Cybernetics to determine […]

What’s in a Name?  Sima Fossils Confuse Human Evolution Story
October 14, 2009
“A hush fell over the room….”  Ian Tattersall had just astonished paleoanthropologists gathered for a meeting on human origins in Gibraltar.  The group was puzzling over a treasure trove of hominin bones found in the mid-1990s at Sima de los Huesos in Spain.  What should they be called?     The co-discoverer, Juan Luis Arsuaga, […]

Step Aside Lucy; It’s Ardi Time
October 2, 2009
A new fossil human ancestor has taken center stage.  Those who love Lucy, the australopithecine made famous by Donald Johanson (and numerous TV specials), are in for a surprise.  Lucy is a has been.  Her replacement is not Desi Arnaz, but is designated Ardi, short for Ardipithecus ramidus – the new leading lady in the […]

Human Evolution Celebration Exposed
September 24, 2009
The evolutionary story of human origins is often told like a cultural myth that is intuitively obvious.  Humans emerged in Africa after their ancestors came down from the trees and walked upright.  They began to hunt with stone tools and used fire.  They migrated north out of Africa and populated Europe, overtaking the Neanderthals who […]

Stone Tools May Be Crocodile Stomach Stones
September 21, 2009
“Were crocodiles responsible for the stones we call tools?” is the title of a surprising letter to the editor in Nature last week.1  Patrick Dempsey (the archaeologist, not the actor) raised a possibility that paleoanthropologists and the journals have been making a big mistake for a long time.  He asked, “Could Nature have been unknowingly […]

Human Evolution Story Confounded – Again
September 9, 2009
Human fossils in Georgia (Asia) have confounded the timeline of human evolution again.  The UK newspaper Independent reported that the 3 skulls of Homo erectus are rewriting the history of man.  If these are as old as claimed (1.8 million years), it would toss overboard the long held belief that modern humans first emerged in […]

Mutation: Not a Bug, a Feature
September 2, 2009
Evolutionary biologists are sometimes risque with the way they discuss mutations.  They treat them almost like magic wands, able to produce wondrous new organs and functions by accident. Health to them, death to you:  One article on Science Daily discussed a mutation that causes congenital heart disease in humans, but may have been a stepping […]

How the Girl Evolved Fear of Spiders
August 29, 2009
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 […]

Fire Technology Began Much Earlier Than Believed
August 14, 2009
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
August 12, 2009
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 […]

The Early Man Gets the Big Brain
July 13, 2009
“Why are human brains so big?” asked Live Science.  Why are our brains larger relative to body size than almost all other animals?  Rachael Rettner reported on various answers.  To her credit, she pointed out the fallacies of trying to test hypotheses when there is insufficient evidence.     Rettner evaluated three hypotheses about why […]

What Makes You Human?
June 17, 2009
If you are a war-mongering beast who likes to burn things, you’re displaying your evolutionary past.  That’s what a couple of news reports are claiming.  New Scientist has a review of two books: Fire: The spark that ignited human evolution by Frances D. Burton, and Catching Fire: How cooking made us human by Richard Wrangham.  […]
