Archive Contributions Introduction First scientists told you that drinking is bad for your health. Then others decided a glass of wine a day is good for your heart. Some scientists believe that the dinosaurs were killed as the result of a giant meteorite striking the earth. Others argue that the evidence for this scenario is sketchy. The answer is simple.
Science is an ongoing search for information about the natural world.
Unlike systems based on faith or consensus, science is based upon systematic observations, formulation of hypotheses, predictions, and relentless tests. And if they don't ask, you can be sure some other scientist will, for science proceeds as a community that is at once cooperative and competitive. In this section we'll keep you abreast of current developments in biology and the controversies surrounding them. And, because science doesn't occur in a vacuum, we'll also introduce you to the social and ethical considerations that these developments raise. We'll pose questions arising from these issues and provide hyperlinks to helpful sites.
