You should start with a good phylogenetics textbook.

It's not a simple problem where an answer can be posted here easily. It depends a lot on which 11 species of primates you are looking at, because the common ancestor of all primates dates back near to the root of all mammals and significant diversity has accrued in that time. If your species are all within the great apes, or some other sub-clade of the primates it will be easier.

To get the rate of evolution, you need fossil data to calibrate the phylogenetic tree.

Sir, among 11 my species I have 8 species from grate apes and 3 from macac.

i already had rate of evolution. I calibrate my data in BEAST 2.6 with fossil data. Now i want to know Mutation rate in each branch of my phylogeny.

I had drawn a MJ network in Network10 software from Fluxus Engineering. But it only gives the no of mutation. I think I will take this no of mutation for each species, and divided with the divergence age i got from BEAST to calculate mutation rate per site per year. Though I don't know this process will be correct or not. I certainly need to read more and more to understand things more logically.

Thank you for suggesting this book I will read it.

Hi. POLYPHENE and SIFT can be used for this aim.
