From Science Daily Magazine: When The Earth Dried Out. "About a billion years ago, the continents emerged relatively suddenly from an ocean that covered 95 percent of the Earth's surface, according to a new theory by Eldridge Moores, a geologist at the University of California, Davis. The appearance of large masses of dry land would have caused more extreme weather, changes in ocean currents and the emergence of proper seasons. In turn, these environmental changes may have led to rise in atmospheric oxygen that enabled the explosion of new life forms around 500 million years ago."

From National Dino-Era Vomit Fossil Found in England. "British scientists have discovered the world's oldest fossilized vomit, believed to have come from a large marine reptile 160 million years ago." I can see how a meal of belemnites would be difficult to keep down. Interesting article - not at all nauseating!

From the Guaridan Unlimited Is human evolution finally over?. "For those who dream of a better life, science has bad news: this is the best it is going to get. Our species has reached its biological pinnacle and is no longer capable of changing....'If you want to know what Utopia is like, just look around - this is it,' said Professor Steve Jones, of University College London, who is to present his argument at a Royal Society Edinburgh debate, 'Is Evolution Over?', next week. 'Things have simply stopped getting better, or worse, for our species." This ought to be an interesting debate, particularly coming from Steve Jones. He wrote the excellent Darwin's Ghost: the Origin of Species Updated. Check out this article and Jones' book.
