The most adaptable to change, survive

I'm about half way through the book Practices of an Agile Developer: Working in the Real World. What a great read! Lots of real world experience, pratical stuff that can be used outside software engineering too. One standout quote is attributed to Darwin: "It is not the strongest of the species that will survive, or the most intelligent. It is the most adaptable to change." I should get to the end of it by Friday. Note to self: recommend to SupportEng guys.
