Whale Sonar: Necessity Is the Mother of Invention

September 5, 2007

Biosonar is a complex ability possessed by toothed whales and dolphins, bats and some birds. It includes both the ability to produce signals and to process the echoes to locate prey. How could such a system evolve? Scientists at UC Berkeley proposed an answer. The press release promised a developing story: Behind the sailor’s lore […]

Do Genes Reveal the Cambrian Explosion?

September 4, 2007

A Croatian geneticist believes he can find the Cambrian Explosion in the genes. Science Daily told about Tomislav Domazet-Loso from the Rudjer Boskovic Institute in Zagreb, whose team employed a “novel methodological approach in evolutionary studies” they called “genomic phylostratigraphy.” Looking for a “genetic trigger” for the Cambrian explosion, they hoped their method can “shed […]

Birds Eat Dark Moths, Therefore God Does Not Exist

September 3, 2007

Michael Majerus watched birds eat peppered moths from his window for seven years (06/25/2004), then drew his conclusions. In a presentation to a science conference in Uppsala, Sweden on August 23, he said that the peppered moth story proves evolution, which means there is no supernatural being to save us, there is no second coming, […]

Ararat Anomaly to Be Imaged in Hi-Res

September 2, 2007

The “Ararat anomaly,” an unusual structure at the 15,300′ level of Mt. Ararat in Turkey, is getting increased scrutiny with high-resolution satellite imaging. Leonard David reported on Live Science that Porcher Taylor of Satellite Imaging Corporation has created a 3-D flyover movie of the site from Ikonos satellite data, and that Geo-Eye I, to be […]

Messy Evidence Proves Humans Evolved

September 1, 2007

An article from Live Science seems to suggest that the way to do science these days is to believe things in spite of the evidence – at least when it comes to human evolution. In a juxtaposition of imponderables that might make a schizophrenic feel at home, Meredith Small asserted that evolution is a fact […]

Solar System Solved?

August 30, 2007

Those who deal in models of the origin of the solar system sometimes have to entertain themselves to overcome grief. See if you can detect this attitude in the following Stupid Evolution Quote of the Week from Space.com: “This has been a stumbling block for 30 years,” said Mordecai-Marc Mac Low, an astrophysicist at the […]

Is the Universe Hole-y?

August 29, 2007

Cosmologists are trying to avoid a void. Since astronomers at U of Minnesota announced a gaping hole in a distant part of the universe, representing a region of space devoid of matter a billion light-years across, others are scrambling to discern what it means. The issue was discussed on EurekAlert, BBC News, Science Now, and […]

Solar System News

August 28, 2007

A flurry of discoveries about the Sun’s family has some scientists smiling and others furrowing their brows. Astrobiologists, as usual, are wielding their divining rods, looking for water. Some of these reports surfaced at the European Planetary Science Congress last week at Potsdam, Germany; see agenda and press releases at Europlanet. Basalt assault: How did […]

Tales of Two Footprints

August 27, 2007

Footprints in the sands of time have been found at two different locations. What tales do they tell? One is a footprint of a Roman soldier. EurekAlert described how the sandal print was uncovered at Hippos, or Susita, on a hill east of the Sea of Galilee. It hints that soldiers participated in […]

Evolution Takes Credit

August 24, 2007

It may be more blessed to give than to receive, but evolution often just takes.

Fossil Gorilla Forces Hominid Ancestor Earlier

August 23, 2007

A set of gorilla teeth found in Ethiopia pushes the evolutionary story of a split between apes and humans back almost twice as far as previously thought. Nature reported the fossil announcement that estimated the date of the teeth as 10.5-11 million years old.1 The prior estimate for a human-ape divergence was about 6 million. […]

Hollywood Film to Expose Darwin Dogma

August 22, 2007

Darwin is going to get a surprise on his birthday next year. Ben Stein is releasing a film on Feb. 12, 2008, entitled “Expelled: No Intelligence Allowed.” The gift may not be what Darwin wants. The press release subtitle asks, “Whatever happened to free speech?” Apparently Premise Media decided to document the trend among Darwinists […]

Two Ways to Look at a Fin

August 21, 2007

Two science articles this month showed very different ways to look at a fish fin. One looked for evolution; the other looked for design. One tried to trace an evolutionary story with no practical application; the other tried to find ways to improve our lives. The evolutionary story involved a fossil coelacanth. Science […]

Crows Use Tools on Tools

August 21, 2007

Crows can use one tool on another to get food. A report in Science Daily says they appear to use analogical reasoning, not just trial and error, to figure out how to manipulate objects. They used a short stick to get a longer stick out of a toolbox in order to reach a snack too […]

Mystery of the Ultraconserved Elements, Cont.

August 18, 2007

ejerano et al reported ultraconserved elements in the human genome (05/27/2004). These were non-coding regions that, for some unknown reason, showed no evolution between mouse and human – a time span over tens of millions of years. Since many of these ultraconserved regions are also found in bird genomes, they added that some genetic regions […]
