[A very brief heads-up for (theoretical) biologists.]
If you’ve wanted to dabble in the theoretical side of evolutionary genetics perhaps you could do worse that read long-time evolutionary geneticist Joe Felenstein’s draft of his text Theoretical Evolutionary Genetics.
It’s available free from his website as a PDF file. Background on the origins of the book is there, too.
This isn’t a beginner’s book – it’s a text for (part of) his Genome 562 course. Readers will need to have a handle on biological concepts and a modest grasp of mathematics.
