Sometime between 28,000 and 30,000 years ago, an anatomically modern human in what is now France may have eaten a Neanderthal child and made a necklace out of its teeth, according to a new study that suggests Europe's first humans had a violent relationship with their muscular, big-headed hominid ancestors. The evidence, which includes teeth and a carefully butchered jawbone from a site called Les Rois in southwestern France, could represent the world's first known biological proof for direct contact between the two human groups.

Finding a fossil in a coal mine is no big deal. Coal deposits, after all, are petrified peat swamps, and peat is made from decaying plants, which leave their imprints in mud and clay as it hardens into shale stone. But it was a different thing entirely when John Nelson and Scott Elrick, geologists with the Illinois State Geological Survey, examined the Riola and Vermilion Grove coal mines in eastern Illinois. Etched into ceilings of the mine shafts is the largest intact fossil forest ever seen—at least four square miles of tropical wilderness preserved 307 million years ago. That's when an...

Obama campaigned on it and even managed to talk about it a full week into office, issuing an executive order on January 23, 2009, promising to create "an unprecedented level of openness in Government" and "establish a system of transparency, public participation, and collaboration." As usual with the words that float so effortlessly from politicians, they were just words. Undoubtedly, they will be paraded about from time to time like a USSR military review--whenever it's convenient to do so. One very important place where transparency is being hidden behind closed doors involves the very inconvenient science behind charging the EPA...

Polar bears are not dying out and Turkey Twizzlers are fine, according to a new book from scientists wishing to challenge science "scare stories" Contrary to widely held belief, polar bear populations are rising, according to the scientists But a new book, compiled by Stanley Feldman, a professor of anaesthetics at London University, and Vincent Marks, a former professor of clinical biochemistry and dean of medicine at the University of Surrey, are questioning the end of the world and healthy eating tips.

The jobs are risky, but very lucrative for those willing to take the risks, and require no previous experience or special training. Almost anyone with a driver's license (or at least the ability to drive) can do this job. How did Obama do it? What People Who Don't Smoke Look Like A recent Senate vote brought tobacco under the regulation of the FDA. The effort, spearheaded by Sen. Ted Kennedy, D-Mass., in the Senate and Calif. Democrat Henry Waxman in the House (no doubt because of their medical expertise—Kennedy, for example, is considered the government's chief expert on alcohol consumption)....

Homosexual behavior seems pointedly un-Darwinian. An animal that doesn't pass along genes by mating with the opposite sex at every, well, conceivable opportunity, seems to be at an evolutionary disadvantage. So what’s in it for the 450-plus species that go for same-sex sex? Two evolutionary biologists from University of California, Riverside, set out to answer that question in a paper published today in Trends in Ecology and Evolution. "It's been observed a lot," says Nathan Bailey, a post-doctoral researcher at U.C. Riverside and lead study author, of same-sex sexual behavior in animals. "But it took people a long time to...

Bird wings clearly share ancestry with dinosaur "hands" or forelimbs. A school kid can see it in the bones. But paleontologists have long struggled to explain the so-called digit dilemma. Here's the problem: The most primitive dinosaurs in the famous theropod group (that later included Tyrannosaurus rex) had five "fingers." Later theropods had three, just like the birds that evolved from them. But which digits? The theropod and bird digits failed to match up if you number the digits from 1 to 5 starting with the thumb. Theropods looked like they had digits 1, 2 and 3, while birds have...

Here, we look at a rather different proposal: the decidedly non-standard, non-mainstream Birds Come First (or BCF) hypothesis proposed by George Olshevsky. Rightly or wrongly, BCF has never been discussed in the technical literature (I have at least alluded to it in historiographical articles (Naish 2000a, b)), and all of George's articles on it have been in the 'grey' or popular literature (Olshevsky 1991, 1994, 2001a, b). Thanks, predominantly, to his activity on the dinosaur mailing list (a popular discussion list for dinosaur aficionados and researchers), George's BCF hypothesis was once well known and much discussed, and perhaps considered seriously...

Darwin-Only Advisors Hunker Down to Re-Strategize June 12, 2009 — Strict Darwinian materialists are a minority in the United States, yet they enjoy autocracy in educational policy, complete control of scientific institutions, and nearly complete unquestioned support from the mainstream media. Nevertheless, they have to face living in a country that is predominantly religious. Once in awhile they suffer setbacks, like the recent changes in textbook policy in Texas that will require more scrutiny of the claims of evolution. What do they say amongst themselves when strategizing how to handle the public?...

Guppies are small fresh-water fish that biologists have studied for long. UC Riverside-led study shows wild Trinidadian guppies adapted in less than 30 generations to a new environment RIVERSIDE, Calif. – How fast can evolution take place? In just a few years, according to a new study on guppies led by UC Riverside's Swanne Gordon, a graduate student in biology. Gordon and her colleagues studied guppies — small fresh-water fish biologists have studied for long — from the Yarra River, Trinidad. They introduced the guppies into the nearby Damier River, in a section above a barrier waterfall that excluded all...

According to Benjamin Wiker’s provocative new biography, The Darwin Myth: the Life and Lies of Charles Darwin, Charles Darwin was an honorable and likable man, a family man. He loved his siblings; he was devoted to his wife; he loved his children and grieved deeply over his daughter’s death. But Darwin was also someone who presented to the public an elaborate and even deceptive story about himself and his work to advance a philosophical agenda. While there are many biographies of Charles Darwin, Wiker’s deserves attention because...

Our large brains may make us cognitively superior to chimps, but, according to a new hypothesis, we could be paying a price for our sizable cerebrum: a higher rate of cancer. Chimpanzees are thought to be the closest evolutionary relative to humans, and we share around 98 percent of our genes with these primates. But for years, scientists have observed that chimps have a surprisingly low cancer rate compared to humans.

June 9, 2009 — In the artwork, it looks so simple: dust clumps into planets that grow into nice, orbiting solar systems – like ours. It’s not so simple when you try to nail down the real physics. Planet-building models have to contend with a host of variables and barriers to growth (accretion). Another barrier was discussed in Astrophysical Journal this month: the electric barrier...

Opinion What 'Ida' give for a missing link By: Casey Luskin, OpEd Contributor 6/8/08 As a follower of the evolution debate, I love it when new “missing links” are found. Not only does the media plunge headfirst into a crusade for Darwin, but suspiciously, it is only after unveiling the breakthrough that evolutionary biologists admit how precious little evidence they previously held for the evolutionary transition in question. Take the recent media coverage of a fossil primate named “Ida,” hailed as the “eighth wonder of the world,” whose “impact on the world of palaeontology” is being compared to “an asteroid...

A breakdown of the news from last week on global warming.

Bismarck, N.D. (AP) Snow has fallen in Dickinson in June, the first time in nearly 60 years the city has seen snow past May.

Millions of years ago, rivers ran in Antarctica through craggy mountain valleys that were strangely similar to the modern European Alps, Chinese and British scientists reported on Wednesday. In a study published by the British journal Nature, the scientists described a vast terrain that had been hidden beneath ice up to two miles thick for eons, until new imaging technology recently uncovered them. "The landscape has probably been preserved beneath the ice sheet for around 14 million years," the paper said. The imaging revealed "classic Alpine topography" similar to Europe's Alps, showing that rivers had once existed on Antarctica and...

Faking scientific data and failing to report commercial conflicts of interest are far more prevalent than previously thought, a study suggests. One in seven scientists says that they are aware of colleagues having seriously breached acceptable conduct by inventing results. Around 46 percent say that they have observed fellow scientists engage in "questionable practices," such as presenting data selectively or changing the conclusions of a study in response to pressure from a funding source. However, when scientists were asked about their own behavior, only 2 percent admitted to having faked results.

Are you someone who squirms when confronted with slime, shudders at stickiness or gets grossed out by gore? Do crawly insects make you cringe or dead bodies make you blanch? If so, chances are you're more conservative -- politically, and especially in your attitudes toward gays and lesbians -- than your less-squeamish counterparts, according to two Cornell studies. The results, said study leader David Pizarro, Cornell assistant professor of psychology, raise questions about the role of disgust -- an emotion that likely evolved in humans to keep them safe from potentially hazardous or disease-carrying environments -- in contemporary judgments of...
