Racial Evolution Education Proposed
February 24, 2011
Skin color provides a “handy tool for teaching evolution,” says a anthropologist at Penn State. PhysOrg reported that professor Nina Jablonski believes “The mechanism of evolution can be completely understood from skin color.” She proposes using the easily-observed trait in humans to teach evolution to students. “People are really socially aware of skin color, intensely […]
Busted! Planet-Making Theories Dont Fit Extrasolar Planets
February 23, 2011
Famed planet-hunter Geoff Marcy is giving theorists headaches. The leading theories of planet formation won’t stand up to observations of hundreds of planets we know. In National Geographic News reporter Richard Lovett lamented, “The more new planets we find, the less we seem to know about how planetary systems are born, according to a leading […]
New Cambrian Fossil: Missing Link?
February 23, 2011
A weird animal from Chinese Cambrian strata looks like a worm with legs, the whole body studded with spines. Was it on the way to becoming an arthropod? The authors think so, but other members of its group were already known from the Cambrian fossil record. The “walking cactus” with ten pairs of […]
Is Star Formation Understood?
February 22, 2011
Astronomers often speak with apparent confidence about regions of active star formation in nebulae or galaxies. A look at the fine print, however, shows plenty of wiggle room when observations don’t quite match theory.
Human Genome Project Supports Adam, Not Darwin
February 21, 2011
Science magazine last week had a special series of articles on the 10-year anniversary of the Human Genome project. Most of the articles expanded on how different the findings were from predictions. The publication of the genome did not identify our evolution; it did not lead to miracle cures. What it did most of all […]
Titans Methane Lakes Shallow, Dynamic
February 19, 2011
Strange things are happening on Titan, Saturn’s largest moon: lakes are appearing and disappearing. This can only mean that the lakes are shallow and the liquid hydrocarbons in them are moving around. Lakes were discovered a few years ago in the northern regions of the Mercury-size moon. They consist predominantly of methane (CH4) […]
But Is it Evolution?
February 18, 2011
Scientists have been noticing some things that seem contrary to Darwin’s predictions – but they give Darwin credit anyway. Not till us: The chambered nautilus is a “living fossil,” that uses “jet propulsion,” New Scientist said, with origins way back in the Cambrian. Has its fitness improved over all that time? “Its movement is ungainly […]
Plant Accelerates 600 G’s
February 17, 2011
Among the fastest organisms in the world is – a plant. The bladderwort Utricularia, a carnivorous plant that lives in the water, sucks in its prey in a thousandth of a second with an acceleration 600 times the force of gravity. New Scientist and Science Daily reported on work by the University of […]
New Ediacaran Fossils: Do They Ignite the Cambrian Explosion?
February 17, 2011
Well-preserved fossils of seaweed-like colonies have been reported from China. They are dated by the scientists at 600 million years old, from the Ediacaran period. Can these be missing links, lighting the fuse of biodiversity that culminated in the Cambrian explosion? PhysOrg summarized the findings published in Nature.1 “In addition to perhaps ancient […]
Anthropology: a Science in Crisis
February 16, 2011
Students memorize the different -ologies of science – geology, biology, paleontology and others – often without knowing the history of the fields. An impression is sometimes given that each branch of science has equal validity. Some recent articles indicate that anthropology (the study of man) is struggling with internal squabbles and external credibility. […]
Critical Thinking Needed in Science Education
February 15, 2011
Several recent articles noted that students are being dumbed down in science education. Can this be applied to their learning about evolution? PhysOrg reported that critical thinking has been called into question at the university level of education. “A post-secondary education won’t necessarily guarantee students the critical thinking skills employers have come to […]
Bubble Life Could Have Had Armor
February 14, 2011
A headline posted by Science Daily is self-explanatory: “Clay-Armored Bubbles May Have Formed First Protocells: Minerals Could Have Played a Key Role in the Origins of Life.” The operative words are may have and could have, which, being mere suggestions, are unfalsifiable. If it didn’t happen here, it may have or could have happened on […]
Tipping Point for Embryonic Stem Cells?
February 13, 2011
At any time, courts could rule on whether funding of embryonic stem cell research can continue or must be halted. Whichever way a decision is rendered, whether by Judge Lamberth on the legality of the NIH guidelines, or by the Court of Appeals for DC, the issue will probably wind up before the Supreme Court. […]
Chernobyl Mutation Experiment Fails to Support Darwinism
February 12, 2011
Bird brains are getting smaller in the region around Chernobyl. Organisms in the vicinity of the radiation from the nuclear disaster 25 years ago have not improved, but suffered under the onslaught of mutations. There is no evidence of any population increasing in fitness in any way; on the contrary, animals are struggling to survive. […]
This Is Your Brain on Bytes
February 11, 2011
It’s mind-boggling time. Some recent articles have tried to quantify the information capacity of the eye, the brain, and the world. Ready? Think hard. Eye boggle: Your eyes contain about 120 million rods and 6 million cones each. If each receptor represents a pixel, that is 2 x 126 million pixels, or 252 megapixels. And […]
