New Genes Don’t Fit Mr. Darwin
May 1, 2007
If evolutionists predicted the wealth of new data from genetics was going to fall nicely into an evolutionary picture of Darwin’s tree of life, nature has foiled them again.  Ancestral patterns are blurred by unexpected findings, such as the following: Little giants:  Small, simple.  Large, complex.  That’s the old high-school picture of genetic evolution, but […]

Box Jellyfish Sees and Reacts with “Human-Like Vision”
April 1, 2007
Who would expect a jellyfish to have complex eyes?  Updating what we reported previously about complex optics in the 24 eyes of the box jellyfish (see 05/15/2005), Live Science says the most complex eyes are found on the top and bottom of the cube-like “head” of the animal, “giving it an extreme fish-eye view, so […]

Turtles Hurtle Through the Sea Magnetically
March 6, 2007
Experiments on sea turtles have shown that they follow the earth’s magnetic field to the exact beach where they were born to lay their eggs.  “It is almost as if they were equipped with a compass pointing towards the beach in question,” says an article on EurekAlert.  “So they can correct any deflection they are […]

Submarine, Make Like a Fish
February 21, 2007
Submarine designers are learning a thing or two from fish.  The latest fish trick to imitate is the lateral line: a row of specialized sensors fish have along their flanks.  Fish use these for synchronized swimming and predator avoidance.  EurekAlert reported on work by scientists at University of Illinois at Urbana-Champagne to build artificial lateral […]

Fossil Fish Meat Pushes Idea of Early Complexity
February 12, 2007
An article in National Geographic News today has a title to catch the eye (or nose) of seafood lovers: “Fossil Meat Found in 380-Million-Year-Old Fish.”  Knowing how quickly fish spoils if left out, this might strike a reader as surprising.  Sure enough, fossilized muscle, with “bundles of muscle cells, blood vessels, and nerve cells” clearly […]

Squid Eye Beats Zeiss
January 29, 2007
A squid whose scientific name means “vampire from hell” wears specs with excellent specs (that’s lenses with excellent specifications, for the pun-challenged).  Elisabeth Pennisi in Science reported on a talk given at an Arizona science conference about the vampire squid, whose “lenses are designed for seeing details, even in virtual darkness.”  Researchers studying cephalopod eyes […]

Tiny Fish Smell for Miles
January 24, 2007
Fish hatchlings no more than a few millimeters in size are able to find their way home by smell, scientists from James Cook University found.  After hatching from a reef, baby fish are often swept out to sea for miles.  The scientists were curious how they are able to get back to the particular spot […]

Urchin Genome Hyped by Media as Human Cousin
November 10, 2006
The publication of a new genome for a plant or animal is becoming routine.  For some reason, the news media instantly jumped on claims that the genome of the sea urchin, published in Science, means that evolution is all but figured out, and that we should each feel a special place in our hearts for […]

Bacteria Rule the World – Benevolently
August 2, 2006
We should love bacteria, not annihilate them.  Bacteria are our friends, according to Dianne K. Newman of Caltech:1 As a microbiologist, I’m appalled when I go to buy soap or dishwashing detergent, because these days it’s hard to find anything that doesn’t say ‘antibacterial’ on it…. It’s a commonly held fallacy that all bacteria are […]

Do Guppies Make Good Darwinian Grandmothers?
December 31, 2005
If a report on EurekAlert is right, some evolutionary biologists used lack of evidence for natural selection as confirmation for evolution.  They predicted guppies would show no evidence of a “grandmother effect” on life history after reproduction, and “that is what they found.”     The question under study is why evolution keeps aging individuals […]

Bombardier of the Sea
December 28, 2005
Creationists have made much of the bombardier beetle (#1, #2) whose firing chambers would explode if the timing and mixture of ingredients did not work perfectly together.  Now, here is a similar case in the lowly sea slug.  EurekAlert described research by Georgia State University scientists, who found that the sea slug Aplysia mixes three […]

How Blind Cave Fish Lose Color
December 26, 2005
A study on cave fish revealed that several populations can have mutations to the same gene.  A gene that produces melanin, named Oca2, was found to be mutated in two separate populations of cave fish, resulting in albinism.  This same gene can produce albinism in humans. The replicated experiment is a powerful tool for experimental […]
