I was glad to hear Richard emphasize the fact that each successive generation of our ancestors looked the same as the prievious. Many people do not understand that evolutionary change is usually tiny down at the molecular level and usually requires many generations of accumulation before a line has established an easily visible change. I often hear the question, "when the first man evolved, where did he find the first woman?" Realizing that the urge to hit one's own head in this condition is only self-destructive, I try to go back to the example of a baby changing into an adult which is hard to put a date to, but we know it when we see enough of the accumulated change.
