I think JLT referred to change in chromosome number in particular with plant speciation (BTW thanks JLT for responding with reasons why you believe what you do and providing resources). If I understand this correctly, chromosome mutation brings about replication of sections of DNA. This can result in replication of a section of DNA that could then be potentially used to serve some function independent of the gene it was replicated from. But this replicated section is dependent upon either further chromosome mutation or point mutations (which are extremely rare and usually damaging). I know this is a popular theory for macroevolution but it seems to have significant problems. For a more detailed explanation: “Simulating Evolution by Gene Duplication of Protein Features that Require Multiple Amino Acid Residues,” Protein Science 13 (2004): 1-14. It’s written by Michael J. Behe (not your favorite person I know) and David W. Snoke
