Science Slowly Explaining Evolution Detail
Chicago IL (UPI) Feb 13, 2006 Scientists say they are starting to understand the details of evolution and, in doing so, they're solving the riddles on which intelligent design is based. Intelligent design posits Charles Darwin's theory of evolution is wrong; life is so complex only an intelligent entity, God, could have produced it. Although scientific research is not conducted as a response to intelligent design, it is unraveling the very riddles that ID proponents say could not be solved, The Chicago Tribune reported Monday. Most scientists reject intelligent design, claiming it's a religious proposal not grounded in scientific observation. ID adherents, counter by arguing many tiny mechanisms, such as the tails of sperm and blood clotting, are so elaborate they must have been purposely designed. Yet scientists are now using new genome data to discover how fish evolved the ability to clot blood, the Tribune said. And even the once-mysterious sperm's tail now appears related to other cell parts. "Once you take apart any system in the cell, you find it's incredibly complex," Joel Rosenbaum, a professor at Yale University, told the newspaper. "But that complexity is (now) falling to experiment."

Introduced Predators Throw A Wrench In The Food Web
Missoula, MT (SPX) Feb 08, 2006In an extensive study, researchers from the University of Montana, University of California - Santa Cruz, and the University of California - Davis have shown that a top predator strongly affected plants and animals at the bottom of an island food web by eating organisms that transport nutrients between ecosystems. "An introduced predator alters Aleutian island plant communities by thwarting nutrient subsidies," is published in the February issue of Ecological Monographs. |
