That isn't true. There most certainly can be new knowledge at the undergraduate level, and increasingly many schools are encouraging or requiring real research projects for both BAs and BS degrees. My wife was published for her biology thesis on petroleum consuming microbes and I was for my research & exhibit on the commercialization (via ephemera) of Thomas Jefferson since his death. That said, my actual thesis, on the impact of popular music on public opinion during WWI, was completely regurgitated hash. However, my university has an enormous collection of period sheet music so it was a lot of fun to research and I don't regret it at all. Hopefully my thesis advisor didn't, either. :)
