What is the best textbook on evolution?

I went to Amazon to look for a good textbook, but I couldn't find one that addresses discussions of evo-devo and the importance in evolution of mechanisms such as mutations in regulatory regions of proteins, gene duplication and divergence, and the modularity of protein structure and how exon shuffling can instantly produce new proteins with new functions. These genetic mechanisms are much more important in evolution than mutations in the structural regions of proteins, which tend to be highly conserved even at the phylogenetic level. Any help in these specific areas is greatly appreciated.
