Hello, 

You can go for the ExPASy bioinformatic resource portal.. there u will get many evolution based tools... just look towards the left of the home page . I hope it will help you.

What are your biological questions actually?

There are many tools to study protein evolution at different level. The first step would be to build a phylogenetic tree (i.e. with FastTree, PhyML, RAxML or MrBayes).
