There are (many, I think) groups working on the evolution of chromosomes
through mammalian lineages (as far divergent as the monotremes). They map 
where various common genes occur in different species, and thereby workout
how chromosomes have rearranged throughout mammalian evolution. One group 
I know of is Prof Jenny Marshall-Greaves'(sp.?) group at LaTrobe University,
Melbourne (sex determination is their specialty), but there would be many
others. I have seen several papers on chromosomal rearrangements and the
relationships of humans to other primates, but unfortunately I don't have
any references here at work!
