Actually paralogs are just duplicated genes. If the duplication event
has happened before speciation of two (or more) species you are
investigating, these species can share the paralogs.
See the following paper for the original definition.
Fitch, WM "Distinguishing homologous from analogous proteins"
Syst. Zool. 19(2), 99-113 (1970).
He may have recently published a paper about this issue on TIG.
