They are the right combination of breeding quickly, maturing quickly, being easy to care for, being easy to handle, and being close enough to humans to get meaningful results.

We might get slightly more analogous results testing with gorillas, but a 400 pound animal that takes 15 years to mature, has one offspring a year, and that can rip you head off isn't worth it.
