March Moon Madness Arrives Early
February 16, 2010
Some of the most interesting bodies in the solar system are the objects not big enough to be called planets. Moons, asteroids and comets continue to yield their secrets and surprises. Here’s a quick rundown on recent findings. Why do some asteroids look so fresh? It’s because they get a facelift, Space.com reported […]
Life Is Smarter Than We Know
February 15, 2010
How can toads calculate? How can cells without a brain or central nervous system figure out a balanced diet? How can bugs navigate the wind for optimum flight time? These are some of the questions that can arise from observations of the living world. The more we learn about life, the more we find unexpected […]
Is Your Bod Flawed by God?
February 14, 2010
Are your body’s imperfections reasons for you to reject intelligent design and embrace evolution? Professor John Avise (UC Irvine) thinks so. His new book Inside the Human Genome was given good press by PhysOrg: “Distinguished Professor of ecology & evolutionary biology at UC Irvine, Avise also makes the case that overwhelming scientific evidence of genomic […]
For His Birthday, Darwin Gets a Scrambled Arthropod Tree
February 12, 2010
If Darwin lost his tree last year (01/22/2009), it would seem any corrections or rearrangements would be academic. Nevertheless, eight evolutionary biologists at Duke University tried rearranging one of the biggest branches on Darwin’s tree of common ancestry – the highly diverse group known as arthropods (animals with jointed appendages). Arthropods comprise the largest number […]
More Surprises for Darwin
February 11, 2010
It’s not uncommon for theories to have to deal with anomalies, but Darwinism sure seems to get more than its share. Here are some recent examples. Fossils lie: Fossils preserve unmistakable clues about past life, right? Not so fast. Nature reported that “Non-random decay of chordate characters causes bias in fossil interpretation.”1 The way early […]
Life Masters Physics
February 10, 2010
Living things, especially cells, have mastered the forces of advanced physics in ingenious ways. This ingenuity sometimes inspires physicists to try to copy it. Here are some recent examples: Photosynthesis and quantum mechanics: Nature reported that plants take advantage of quantum mechanics in photosynthesis.1 “The photosynthetic apparatus of cryptophyte algae is odd – its pigments […]
Dinosaurs Evolved from Birds
February 9, 2010
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
February 9, 2010
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?
February 8, 2010
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
February 7, 2010
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
February 6, 2010
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
February 5, 2010
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
February 4, 2010
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
February 3, 2010
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
February 2, 2010
“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 […]
