I've just finished reading Darwin's Origin of Species - A Biography and I realize I'm not much closer to understanding the subtleties of evolutionary theory. At least, I think I'm not. What Darwin brought to the world, while it rocked the foundations of biology, was not his alone. The concept of "change over time" was pretty well accepted by many progressive scientists, though the subtleties of what's driving the changes was in debate. There are some very simplistic concepts around evolution that circulate in the general public. Many of them are attributed to Darwin (such as the phrase "survival of the fittest"), as if he alone invented the whole theory of evolution. How much has our current understanding of evolutionary theory advanced from his initial theories? Where could I look up a current Coles Notes of evolutionary theory in a nutshell? What are the major principles? What are the myths?
