Criticism aside, few can debate the impact that SILENT SPRING has had on our natural world, and in inspiring citizens around the globe to work to protect it. | The centenary of Rachel Carson's birth has been the cause of much celebration (see our profile) and of some renewed criticism.

=====Doctor Darwin: Diseases That Cheat Natural Selection===== | |||

It's a basic tenet of biology that natural selection picks the most advantageous traits and passes them on to the next generation. Why, then, do people still suffer from debilitating genetic diseases? Shouldn't the genes that code for these diseases be removed from the population over time? How did they manage to keep themselves around during the course of human evolution? It turns out that there may be a reason that genes for harmful diseases survive evolutionary selection and pass from generation to generation. | |||
