15 Evolutionary Gems  - provided by the journal Nature, this is a new resource summarizing fifteen lines of evidence for evolution by natural selection.  As the editors explain, "About a year ago, an Editorial in [Nature] urged scientists and their institutions to 'spread the word' and highlight reasons why scientists can treat evolution by natural selection as ....an established fact".

Fossil Crocodile is "Missing Link" -  It has a mix of morphological traits common in prehistoric crocodiles and in the ones that exist today.  The fossil of a land-bound reptile that could be a link between prehistoric and modern-day crocodiles. The  80-million-year-old predator, dubbed Montealtosuchus arrudacamposi, is 5.5-foot-long (1.6-meter-long) and was a long-limbed and extremely agile animal that roamed arid terrain in what is now the Brazilian countryside, As a missing link to prehistoric crocodiles, it offers us an excellent opportunity to study the evolutionary transition of these animals.  For more see National Geographic News (Feb. 2008).

Evolution's Greatest Mistakes -  As miraculous as living things might seem at first glance, a closer look reveals that evolution's blind blunderings often fall well short of perfection. Claire Ainsworth and Michael Le Page peek under the hood of life to assess the parts and processes where things seem to have gone spectacularly wrong. New Scientist 195.2616 (August 11, 2007): p36 (4).

Study Maps Evolution's Tiny Steps -  For the first time, scientists have drawn a detailed map of the evolutionary steps taken by a protein that links modern humans to life that swam in the oceans 450 million years ago. The study, published in the journal Science, provides further rebuttal to creationists by filling in the gaps that show how evolution occurred on a molecular level.

Twin fossil find adds twist to human evolution -  unearthed in Kenya, they show that two ancestral human species seem to have lived cheek-by-jowl in the same area, much as gorillas and chimpanzees do today. Both skull fragments, discovered by Fred Spoor of University College London and his colleagues, were found near Kenya's Lake Turkana, adding to the impressive list of early human fossils unearthed here. One of the fossils, an upper jawbone from the species Homo habilis, is dated at 1.44 million years, younger than most fossils of this species. Read more in the 8/8/2007 issue of the journal Nature.

The Bacterial Flagella Evolved not Designed.  In an article published on-line 9/6/2006 in Nature Reviews Microbiology (or see short summary), Mark Pallen of the University of Birmingham and Nicholas Matzke of NCSE,  review the evidence for the evolution of the bacterial flagellum.  They handily dismiss the need for any great conceptual leaps in creating a model of flagellar evolution and speculate as to how an experimental program focused on this topic might look. 

Growing evidence that evolution is not just real but is actually still happening to humans today.  "From 1970 to 2000, the view was that although natural selection is very important, it is relatively rare,  That view was driven largely because we did not have data to identify the signals of natural selection. In the last five years, there has been a tremendous growth in understanding how much selection there is. Everywhere we look, there appears to be very widespread signals of natural selection in many genes and many processes."  wrote Dr. Jonathan Pritchard, a geneticist at the University of Chicago, in a recent article in PLoS-Biology.  Our insight to evolution and natural selection has  deepened as we have gained the ability to read the human genome.

Irreducible Complexity Refuted - By reconstructing ancient genes from long-extinct animals, scientists have for the first time demonstrated the step-by-step progression of how evolution created a new piece of molecular machinery by reusing and modifying existing parts. The findings offer a counterargument to doubters of evolution who question how a progression of small changes could produce the intricate mechanisms found in living cells. This experiment refutes the notion of "irreducible complexity".

A 375-million-year-old fish fossil with the beginnings of legs - A large scaly creature not seen before, it appears to be a long-sought missing link in the evolution of some fishes from water to walking on land. The skeletons have the fins, scales and other attributes of a giant fish. It shows anatomical traits of a transitional creature, a fish that is still a fish but has changes that anticipate the emergence of land animals — and is thus a predecessor of amphibians, reptiles and dinosaurs, mammals and eventually humans.

A Catholic Scientist and Priest Looks at Evolution - Father George V. Coyne,  Vatican Observatory Director and Jesuit, shares his convictions that  (1)  the Intelligent Design (ID) movement, while evoking a God of power and might, a designer God, actually belittles God, makes her/him too small and paltry; (2) our scientific understanding of the universe, untainted by religious considerations, provides for those who believe in God a marvelous opportunity to reflect upon their beliefs.

Breakthrough of the Year: Evolution in Action  Today evolution is the foundation of all biology, so basic and all-pervasive that scientists sometimes take its importance for granted. At some level every discovery in biology and medicine rests on it, in much the same way that all terrestrial vertebrates can trace their ancestry back to the first bold fishes to explore land. Equipped with genome data and field observations of organisms from microbes to mammals, biologists made huge strides toward understanding the mechanisms by which living creatures evolve. 

Inteligent Design is Religion according to the decision (139 page PDF) in  Kitzmiller v. DoverJudge John E. Jones III concluded that, "The proper application of both the endorsement and Lemon tests to the facts of this case makes it abundantly clear that the Board's ID Policy violates the Establishment Clause. In making this determination, we have addressed the seminal question of whether ID is science. We have concluded that it is not, and moreover that ID cannot uncouple itself from its creationist, and thus religious, antecedents."

"IS IT SCIENCE YET?" Matthew Brauer, Barbara Forrest, and Steven Gey offer a definitive assessment of the legal issues involved in the Dover Pennsylvania trial of Kitzmiller v. Dover in their new law review article published in the Washington University Law Quarterly (2005; vol. 83, no. 1).  With almost 150 pages of closely reasoned argument and almost 600 footnotes of meticulous documentation, "Is it science yet?" is sure to become the leading treatment of the constitutionality of teaching "intelligent design" for the foreseeable future.

SHOW ME THE SCIENCE.  To date, Daniel Dennett says, the proponents of ID have not produced anything. No experiments or observations that undermine evolution.  Instead, the proponents of ID misuse scientist's work, then after an expected angry rebuttal, they cite it as evidence of a "controversy".....

Cobb County Anti-Evolution Stickers: Let’s Get The Facts Right. An appeals court Judge recently criticized the ruling made earlier this year that ordered the removal of anti-evolution stickers placed by the Cobb County school board in textbooks, saying that the words on the stickers are "technically accurate".  They are not, and they contain factual errors and misconceptions. ....MORE

Dover PA - a contemporary Scopes trial 39 years in the making. Chris Mooney  describes how ID theorists and other creationists don’t like what the overwhelming body of science tells us about where human beings come from. Their recourse?

Isn't Intelligent Design 'just' a theory? In fact, says Massimo Pigliucc it is worse: intelligent design is not even a (scientific) theory, it's a idea that used to have some philosophical valence in pre-scientific times, but is clearly dead now. Ironically, ID is "just' a theory" in the derogative sense reserved by creationists for evolution. ID is a hunch of irreducibly superstitious and insecure people who really can't stand the thought of a universe where they are not the center of all attention....MORE

Evangelical Scientists Refute the Theory of Gravity using a Corollary of of Intelligent Design.  "Intelligent Falling" asserts that the theories used by secular physicists to explain gravity are not internally consistent. Secular scientists admit that Einstein's ideas about gravity are mathematically irreconcilable with quantum mechanics. This fact, Intelligent Falling proponents say, proves that gravitational theory is in crisis..... More from The Oinion 8/17/05

President Bush takes a hammering for his remarks about evolution and intelligent design after implying that "...both sides ought to be properly taught...".  As Glenn Branch of the NCSE stated, Bush would have done better to heed his White House science adviser, John Marburger, who has said that evolution was the 'cornerstone of modern biology' and who has characterized ID as not even being a scientific theory." .....

Joy now reigns among some -- but fortunately not all -- citizens of Dover, Pa. - The Dover Area School District board has leaped ahead in the hot competition to be the leading contender in the world series of scientific nonsense and the next school system taken to court for teaching creationism.

An astounding find that may change the world of paleoanthropology, and challenges our perception of what it means to be human.  A possible new species of tiny human has been discovered, which lived on the remote Indonesian island of Flores just 18,000 years ago. Researchers have so far unearthed remains from eight individuals who were just one meter tall, with grapefruit-sized skulls. These astonishing little people, nicknamed 'hobbits', made tools, hunted tiny elephants and lived at the same time as modern humans who were colonizing the area.

Ancestor of Tyrannosaurus rex discovered with clear impressions of downy feathers from head to tail.   The 130-million-year-old fossils from northeastern China provide the first direct evidence that tyrannosaurs had protofeathers and support the hypothesis that some dinosaurs evolved a feathery covering to help them keep warm. Xing Xu, et al. Nature, 2004, 431, 680-4

New genomic-scale data offers powerful, unprecedented resolution of the evolutionary tree. The finding is important because an accurate depiction of a tree of life promises biologists a summary of the history of life on Earth during

Biologists Detail Evolution of Gene Related to Brain's Growth that has been under intense Darwinian pressure in the last few million years, changing its structure 15 times since humans and chimps separated from their common ancestor.

Fossils of 160,000-year-old skulls fill gap in human evolution record and support out-of-Africa theory.
A major discovery of 160,000-year-old "near-modern" humans, the oldest humans yet found, shows a thickly muscled subspecies of Homo sapiens and a wonderful confirmation of human evolution. (T.D.White et al., Nature, 2003, 423, 742-747)

A confirming example of co-evolution, what Darwin first noticed during his famed voyage aboard the Beagle, has been shown by two biologists studying the lives of hummingbirds and flowers on Caribbean islands. A remarkable example of animals and plants that evolve to meet each other's needs. (E.J. Temeles & W.J. Kress, Science, 2003, 300, 630-633).

Artificial Life Experiments That Show How Complex Functions Can Evolve have been carried out by an interdisciplinary team of scientists at Michigan State and Caltech, with the help of powerful computers. They have used a kind of artificial life to create a road map detailing the evolution of complex organisms. These findings show how complex functions can originate by random mutation and natural selection. (R.E. Lenski, et al., Nature, 2003, 423, 139-144 )

Fossils of a four-winged, feathered dinosaur that lived 128 million years ago in trees and glided to earth to seize its prey have been unearthed in China, a find that American scientists say could revolutionize the long debate over the origin of flight in birds (Xing Xu, et al., Nature, 2003, 421, 335-340 ).

"New Study Suggests Missing Link that Explains How Dinosaurs Learned to Fly" (Jan.17, 2003) - Two-legged dinosaurs may have used their forelimbs as wing-like structures to propel themselves rapidly up steep inclines long before they took to the skies, reports a University of Montana researcher in the January 17 issue of the journal Science. The new theory adds a middle step that may link two current and opposing explanations for how reptiles evolved into flying birds.

"Using Computers, Scientists Successfully Predict Evolution of E. Coli Bacteria" (Nov. 14, 2002) - Rresearchers at the University of California at San Diego have created a computer model that accurately predicts how E. coli metabolic systems adapt and evolve when the bacteria are placed under environmental constraints.

Ohio Survey - Scientists Support Evolution, Reject"Intelligent Design" (Oct.11,2002) Ohio university scientists overwhelmingly view "intelligent design" as religious, not scientific. Majority (93%) of scientist were not aware of "any scientifically valid evidence or theory challenging evolution/natural selection."
