Biologists use Google to "destroy" ecosystems

By applying PageRank, the search algorithm that powers the world famous search engine Google, to the food chain of an ecosystem, Biologists have found a way to predict which species may be the most essential to the balance of that ecosystem. By virtually "destroying" the ecosystem by removing certain species from the food chain and observing simulated results, scientists are able to rank species by their importance, according to an article published in Wired magazine.
