Resumo: 	The rapid evolution of the H5N1 serotype of avian influenza has been explained by a mechanism involving the selection of single nucleotide polymorphisms generated by copy errors.  The recent emergence of H5N1 Clade 2.2 in fifty countries, offered a unique opportunity to view the acquisition of new polymorphism in these evolving genomes.  We analyzed the H5N1 hemagglutinin gene from a fatal human case from Nigeria in 2007.  The newly emerged polymorphisms were present in diverse H5N1 isolates from the previous year.  The aggregation of these polymorphisms from clade 2.2 sub-clades was not supported by recent random mutations, and was most easily explained by recombination between closely related sequences.
