This Tree of Life Is Real

March 9, 2010

Imagine a tree that can provide both nutritious food and clean water. Moringa oleifera is such a tree. It grows in Africa and Asia and is being looked at as a life-giving plant that can reduce bacterial contamination of water by 90 to 99.99% by filtering water with its seeds. Science Daily has […]

What Good Is Natural Selection without Progress?

March 8, 2010

Three papers recently claim to have seen natural selection. None of them, however, identified a functional advantage that would have tied changes to novel benefits that could improve a species. Yeast: “New Type of Genetic Variation Could Strengthen Natural Selection,” trumpeted a headline in Science Daily. It was about a study of two varieties of […]

Life Crams Stuff on the Long Road

March 7, 2010

This quote from UC Berkeley wins Stupid Evolution Quote of the Week: In the long evolutionary road from bacteria to humans, a major milestone occurred some 1.5 billion years ago when microbes started building closets for all their stuff, storing DNA inside a nucleus, for example, or cramming all the energy machinery inside mitochondria. Any […]

Natural Wonders Can Be Useful

March 6, 2010

To find great ideas, look to nature. Many plants and animals are as useful as they are ornamental. They can show the way to solve problems of great interest to humans. Mussel power: Want an abrasion-resistant, highly-extensible coating? PhysOrg reported that mussels are providing inspiration to materials scientists. They build a byssus, or network of […]

Dinosaur Evolution Is Relative

March 5, 2010

The science news media are all reporting that the “oldest known dinosaur relative” has been found. The artist reconstructions of Asilisaurus kongwe, found in middle Triassic layers in Tanzania, make the creature look quite dinosaurian; at least it was dog-sized and walked on thick legs under its body like its famous brethren did. Its early […]

Atheism in a Test Tube

March 4, 2010

Conflicting views on atheism by scientists show that deducing the intellectual status of atheism is not an exact science. Are such questions even approachable by the scientific method? What conclusions could be drawn? National Geographic reported Kanazawa’s theory that liberals and atheists are smarter (02/27/2010) without much criticism. Reporter Maggie Koerth-Baker only said […]

Cold Castles: Bad Climate for Imperial Science

March 4, 2010

To some people, the world would be a better place if ruled by scientists. They could be like a benevolent oligarchy, employing the knowledge gained by the scientific method for the good of the people. A recent editorial might shake that belief. In Nature News this week,1 Daniel Sarewitz had some sobering thoughts […]

Ida Not a Human Ancestor

March 3, 2010

If Ida known then what I know now: the media-frenzied presentation of Ida (Darwinius masillae) as a distant relative of human beings last year has been debunked. “Many lines of evidence indicate that Darwinius has nothing at all to do with human evolution,” said Chris Kirk (U of Texas) in an article on Science Daily.

Flight Design: Flies and Birds Get it Wright

March 3, 2010

Parse the following sentence for logical consistency: “Just as the Wright brothers implemented controls to achieve stable airplane flight, flying insects have evolved behavioral strategies that ensure recovery from flight disturbances.” That is the first sentence from a paper in PNAS yesterday about the stabilizers in fly wings.1 Ristroph et al just compared design principles […]

Origin of Life: Claiming Something for Almost Nothing

March 2, 2010

Getting life to emerge from nonliving chemicals is either a cinch or the most impossible thing in the universe, depending on whom you ask. Let’s look at a couple of recent papers that suggest the origin of life was no big deal. A press release from the University of Colorado advertised a paper […]

Depressed? Believe in a Caring God

February 28, 2010

“Belief in a Caring God Improves Response to Medical Treatment for Depression, Study Finds.” That’s what Science Daily said. The statement assumes, of course, that psychiatry knows what depression is. Another story on Science Daily worried that “Psychiatry’s Main Method to Prevent Mistaken Diagnoses of Depression Doesn’t Work.” It makes sense that diagnosis […]

How to Call Your Opponent Stupid Using Evolution

February 27, 2010

It may be that Professor Kanazawa was intending to be compassionate by couching his assessment in the language of evolutionary theory, but he essentially made a categorical judgment that conservatives and Christians are stupid, and atheists and the sexually promiscuous are smart. How could he say such a thing? He could dodge the charge of […]

Life Leads the Way to Invention

February 26, 2010

Here’s a factoid for the party: a cell is 10,000 times more energy-efficient than a transistor. PhysOrg tells us that “ In one second, a cell performs about 10 million energy-consuming chemical reactions, which altogether require about one picowatt (one millionth millionth of a watt) of power.” This and other amazing facts lead to an […]

Making Evolution Simple

February 25, 2010

Getting the vast diversity of highly complex creatures seems an impossible task for evolutionary theory, but some recent stories claim it’s not so hard. Beak of the finch: Darwin’s finches keep pecking their way into the media. A new study claims that the wide diversity of beak shapes that have evolved can be explained by […]
