Anyone read this little book? https://www.amazon.com/Evolution-Ch...=sr_1_3?ie=UTF8&s=books&qid=1213343392&sr=1-3 I'm about 20 pages in and having a really tough time understanding it. I find the mathematical notation to be unclear. I believe the book is based on a series of lectures given by Levins, so that might explain why it seems so terse. Details tend to get lost when you try to read notes of a lecture you didn't attend. If nothing else I'll just skim the book and try to glean some general ideas and results. But it will be a shame if I can't follow the math...the subject matter is very neat.
