Evolution can be a touchy topic but I think Wil gave us some great web sites to check out. This one called  Squirrel/Sugar Glider has much more to it then Wil showed us. Go to the bottom of the page and you will can take an interesting side trip and  you can explore homologous structures in more detail. In college the phase" ontology recapitulates phylogeny" fascinated me. I always explain it in as development mirrors evolution. I never have been able to find good pictures. Click the below and wikppedia will get you to some great pictures.
