Darwin Saves Junk, Makes Treasure Out of It
October 5, 2007
The Stupid Evolution Quote of the Week award goes to a press release from the Howard Hughes Medical Institute, which began by personifying Evolution1 as a tinkerer in its own junkyard: Evolution has mastered the art of turning trash to treasure – though, for scientists, witnessing the transformation can require a bit of patience. […]
Inca Priests Fattened Children for Slaughter
October 5, 2007
National Geographic News had a disturbing story from archaeological studies of Inca rituals in what is now Peru. Studies of hair samples and other features in mummies indicate that the Inca warlords fattened up children for up to a year before slaughtering them. A team that analyzed the mummies believes that captured children were then […]
Modern Crustacean Found in Early Cambrian
October 4, 2007
A “crown-group crustacean” that is “markedly similar to those of living cephalocarids, branchiopods and copepods” has been found exquisitely preserved in early Cambrian fossil beds from China, an international team reported in Nature.1 Though such organisms have been found in middle and later Cambrian rocks, this pushes the origin of eucrustacea (crustaceans of modern aspect) […]
Exceptional Preservation: Can It Last Hundreds of Millions of Years?
October 3, 2007
What can happen in 460 million years? A lot, according to the standard geological timescale. In this diagram of geological and biological evolution, accepted by nearly all geologists, all the continents came together 260 million years ago, broke up 200 million years ago, and broke into our familiar continents 100 million years ago (mya). In […]
One Special Universe: Take It or Leave It
October 2, 2007
If you think this universe is odd, to what would you compare it? Adrian Cho asked this and other basic questions in a whimsical review of cosmology since WMAP in Science.1 Closer analysis of the Cosmic Microwave Background (CMB), as revealed in detail by WMAP (03/06/2003, 05/02/2003, 09/20/2004, 03/20/2006), has uncovered features so surprising (e.g., […]
When Myth Turns Genocidal, Whos to Blame?
October 2, 2007
Aryan mythology was the subject of a book review by Michael Witzel (Harvard linguist) in Science last week.1 He was reviewing Stefan Arvidsson’s book Aryan Idols about the mischief done in the quasi-scientific, quasi-historical investigation of the alleged noble race behind the primitive Indo-European language. The atrocities of Nazi Germany can be traced […]
New Atomizer Mimics Bombardier Beetle
October 2, 2007
There’s a new technology coming to market, thanks to a little bug. The bombardier beetle has long been used by creationists as a creature with a weapon against evolutionary theory. Its tightly-integrated combustion apparatus would be useless or dangerous to the beetle unless all the parts worked together from the start. This, creationists argue, is […]
Bacteria and Plants Know Network Tech
October 1, 2007
An article on Science Daily says, “plants have their own chat systems that they can use to warn each other.” Many herbal plants such as strawberry, clover, reed and ground elder naturally form networks. Individual plants remain connected with each other for a certain period of time by means of runners. These connections enable the […]
Comet Woes: News Reports Hide Backroom Exasperation
October 1, 2007
“Comets are made of the most primitive stuff in the solar system,” a press release from University of Michigan triumphantly claimed today. “As hunks of rock and ice that never coalesced into more planets, they give researchers clues to the evolution of solar systems.” Tell that to Toby Owen and two colleagues who […]
Evolutionists Say Parasites Made Humans Successful
September 30, 2007
“If cooperation has been the secret to our evolutionary success, we may have our parasites to thank for that.” That’s a pretty big If, but that’s what two evolutionary biologists claimed this month Current Biology.1 The cooperative behaviors naturally selected in evolutionary host-parasite wars, by implication, are what gave human beings the ability to build […]
Astronomy Columnist Tackles Naturalism vs. Intelligence
September 29, 2007
Bob Berman is an unusual columnist for a science magazine. He’s independent-thinking, unafraid to tackle big questions and criticize powerful institutions, but all the while able to keep a sense of humor. In his monthly column “Bob Berman’s Strange Universe” in the November issue of Astronomy (p. 10), he took a moment from munching on […]
Molecular Machines Under the Nanoscope
September 28, 2007
Seeing machines just billionths of a meter long seems impossible, but cell biologists are now routinely looking into the cellular black box. Using indirect but powerful methods, they can actually begin to visualize the gears and wheels and cogs of the protein machines that make life possible. Some of our favorite cell gadgets were examined […]
Dont Just Sit There; Evolve
September 27, 2007
Have you ever wondered why your body doesn’t evolve? After all, it is kind of like a population of trillions of organisms. Why shouldn’t it follow the rules of natural selection? Philip Ball asked this question in News@Nature recently. “Evolution is usually thought of as something that happens to whole organisms,” he teased. “But there’s […]
Stem-Cell Advocates Try to Shield Ethical Concerns
September 26, 2007
Would an embryonic stem cell by another name cease being human? Several recent articles on embryonic stem cells are going beyond just touting the potential cures from the controversial research, which involves creating and destroying a human embryo. Some are blurring the line between embryonic and adult stem cells (cf. 12/02/2006) and attempting to avoid […]
Did Evolution Hardwire Our Instincts?
September 25, 2007
Jeanna Brynner in Live Science is claiming that evolution hard-wired our brains to pay attention to people and animals more than to inanimate threats. This is based on a paper by evolutionary psychologists at UC Santa Barbara. The researchers say the finding supports the idea that natural selection molded mechanisms into our ancestors’ brains that […]
