...tons.) It may be high grade, says James Otton, a uranium-resources specialist at the federal U.S. Geological Survey, a reference not to its quality but to the "tremendous quantities of uranium in a given volume of rock" found in places similar to Roraima, a virtual Lost World of Precambrian geology...
...says Dawkins, "is precisely what you would expect if evolution would happen." Dawkins insists that critics of Darwin are wrong to say that evolution has become an article of faith among scientists. He cites biologist J.B.S. Haldane who, when asked what would disprove evolution, replied, fossil rabbits in the Precambrian era, a period more than 540 million years ago, when life on Earth seems to have consisted largely of bacteria, algae and plankton. "Creationists are fond of saying that there are very few fossils in the Precambrian, but why would there be?" asks Dawkins. "However, if there was a single...

I also think that a Clinton presidential candidacy in 2008 would be a disaster on many levels...
Knoll’s research interests include the early evolution of life on earth, the early fossil record of plankton, and interrelationships between crustal, atmospheric, and biological evolution during the Precambrian period...
...fossil record exactly at the transition between the Vendian and the Cambrian, in the form of bore holes drilled through shelly organisms that resemble stacks of miniature ice-cream cones. Seilacher, among others, speculates that the appearance of protective shells and hard, sharp parts in the late Precambrian signaled the start of a biological arms race that did in the poor, defenseless vendobionts...
