If the current rate of extinction continues, Earth will lose some 75 percent of its species in three centuries, according to a new study by U.C. Berkeley scientists published in the journal Nature this week. Mass extinctions, such as the one predicted, have only occurred five times in the Earth’s history. The dinosaur die-off is the best known. [San Jose Mercury News]
