Dinosaurs Evolved from Birds

Birds evolved from dinosaurs, we are often told.  That’s backwards, reply some scientists at Oregon State University.  According to PhysOrg, the recently-published bi-plane model study of Microraptor gui (01/29/2010) demonstrates that theropod dinosaurs did not sprout wings and fly; instead, they became flightless after their bird ancestors came down from the trees.     Their […]

Incredible Preservation of Beetle Wings Found

Beetle wings with their original shimmering luster have been found preserved in fossilized peat in Japan.  The strata in which they were found have been labeled middle Pleistocene and dated at 600,000 years old.  Yet these same wings, when dried in the sun, lose their luster within hours.     The authors of the paper […]

The Evolution of Religion – or Vice Versa?

A Harvard professor has evolutionized religion again.  Marc Hauser, the one who trains his little boy to adore Darwin (07/03/2007) and wrote a book on how natural selection created morality (10/27/2006), is now saying that religion is a by-product of our evolution.  “These findings suggest that religion evolved from pre-existing cognitive functions,” he wrote in […]

Small Hobbit Brain Means Little

Central in the debate whether Homo floresiensis (nicknamed hobbits) were human is the matter of their small brains.  Could diminutive human-like skeletons really be human with such small skulls? (cf. 03/04/2005).     Scientists at the University of Cambridge conducted a detailed analysis of brain size vs. body size for a number of primates.  They […]

Sociology of Science: the IPCC Case

Climate change is off-topic for evolution news, but what is taking place in this internationally-potent paradigm is instructive.  Its troubles provide fodder for several extra-scientific disciplines: the philosophy of science, the history of science, the rhetoric of science, and the sociology of science.  Lessons from the IPCC case can inform citizens about current scientific practices […]

Old Primordial Soup Is Spoiled

Don’t open it; that can of primordial soup sitting on the shelf for decades is rotten. PhysOrg announced, “New research rejects 80-year theory of ‘primordial soup’ as the origin of life.” In its place come new theories about tiny chemical cooking pots in the pores of deep-sea vents. Pioneered by Michael Russell (02/15/2008) and others, […]

Spider Webs Are Precision Dew Collectors

Photographs of dew drops on spider webs are favorite targets for nature photographers, because they resemble strings of pearls on fine jewelry (example 1, example 2).  But did you know the reason dewdrops bead up so well on webs is due to the fine microstructure of the spider silk?  A team of Chinese scientists studied […]

Universe Has a Run-Down Feeling

There’s 30 times more entropy in the universe than thought, according to Dr. Charley Lineweaver at the Australian National University.  PhysOrg said that Lineweaver and a PhD student Charles Egan measured the entropy of the universe.  It looks like it is feeling pretty run down.  “We considered all contributions to the entropy of the observable […]

Building a Cell: Staggering Complexity

“The living cell is a self-organizing, self-replicating, environmentally responsive machine of staggering complexity.”  Thus began a special section on “Building a Cell” in Nature last week.1  The section with five papers explores what is known about gene regulation, cell organization and signalling.  It’s an opportunity, as well, to see what scientists think about what they […]

SETI, Miracles, and Comfort

Would knowledge that the universe is filled with aliens bring you comfort?  Or are you more comfortable thinking humans are alone in the universe?  Seth Shostak, director of the SETI Institute, was interviewed briefly by Bill Hemmer on Fox News this morning, where only one answer to this idea was assumed.     Shostak came […]

Who in the Universe Makes Music?

A cosmologist and some musicians want to “sonify the universe” by making music out of stellar events like supernova explosions.  In an unusual article for a science media outlet, “Reaching for the Stars to Create Music of the Universe,” Science Daily reported that Nobel laureate George Smoot was inspired by the wishes of a Grateful […]

Scientists Divine Deep Time in Dead Fish

Scientific experiments can certainly take on a wide variety of methods, from recreating the atmosphere of Titan to testing a drug on a genetic disease.  But if educators want to encourage students to become scientists, they had best keep silent about “some very unpleasant experiments” at the University of Leicester reported by the BBC News.  […]

Incredible Creatures that Support Evolution?

Paleontologists and biologists continue to uncover animals past and present that exhibit amazing diversity. Some of them are so weird and unexpected, they are almost unbelievable. Usually, the news media are quick to tally up points for Darwin by explaining to lay people how they shed light on evolution. But in the “discovery” stage of […]

Woese Slays Darwin

The king is dead!  Long live the king!  Such were the oxymoronic cries of olden times when royal succession took place.  Has Charles Darwin been dethroned?  One would think so, after reading Mark Buchanan’s article, “Horizontal and vertical: the evolution of evolution” in New Scientist.  Buchanan sets the stage: Just suppose that Darwin’s ideas were […]

Barefoot Is Better

Who do we wear shoes?  It seems obvious; we expect that they help us avoid injuries and provide comfort.  Maybe we should think of the injuries we are getting by wearing them.     The image of the barefoot person is usually of someone poor, deprived, lower-class, hick, unclean, redneck or something else unattractive.  Shoes […]
