People tend to look at me crazy when I tell them that I've read ORIGIN OF SPECIES. And really, I think we can all see where they are coming from. Nevertheless, being curious, I thought it might be interesting read the book that started all the fuss.
I was surprised to find how readable it really was. Think about this: what we are taught in high school biology is way more than Darwin knew when he wrote this book. Accordingly, the science described in this book is quite easy to understand for anyone who has previously taken a biology class.
Probably the most interesting thing about this book were the few times that Darwin threw in a little philosophical/theological side comment. I'll leave these juicy tidbits for you to find, but look for them as they add a little "kick" to an otherwise fairly "scientific" book. Though a bit lengthy, this accountant enjoyed ORIGIN OF SPECIES.
As a sidenote: I find the funniest thing about those "Jesus fish" eating the "Darwin fish" car decals is that the base idea is that the stronger fish wins- a.k.a. surival of the fittest. The ensuing contradiction of unwittingly using one of Darwin's base tenets to attack Darwinian evolution is priceless.
