Summaries And Excerpts

Mutations arise from errors made by the cell's genetic copying machinery. I have found from experience that most organisms prefer to be called by heir common names rather than by their technical Latin names — after all, few humans talk of themselves as Homo sapiens — so I use Latin names only when necessary for clarity or when the organism I am discussing is too obscure or too snobbish to have a common name.

Description: For most of us, caught up in the hurly-burly of our daily struggles, the purpose of life may seem elusive. And which is why I have dedicated my life to answering them. Which is not to say that sex makes life easy. They typically include one or more of the following features. Yet mutation by itself is not enough. Worse, success at seduction is often at odds with survival. Which is why everyone asks so many questions. To see why, let's take a step back and think about how evolution works.
