Hi!
I am looking for core books/papers on evolutionary mechanisms, specially in natural selection (directional, disruptive, stabilizing natural selection). I'm a physical anthropologist and I would like to reference important works on them. I have search but I have mostly found studies in very specific cases, and I am interested mainly in the broader concepts that I can use in my thesis.
I am aware of On the origin of species of course :) anything more recent?
Thank you in advance
