Segments of the 2009 human H1N1 strains have coexisted in swine influenza virus strains for more than 10 years. Vladimir Trifonov, Hossein Khiabanian, and Raul Rabadan describe the evolution of the H1N1 virus.

Experimental inoculation of pigs with pandemic H1N1 2009 virus and HI cross‐reactivity with contemporary swine influenza virus antisera
TLDR
Experimental inoculation of pigs with pandemic H1N1 2009 virus and HI cross‐reactivity with contemporary swine influenza virus antisera shows cross-reactivity between 2009 and 2010.
Host Dependent Evolutionary Patterns and the Origin of 2009 H1N1 Pandemic Influenza
TLDR
The evolution of H1N1pdm ancestors with other influenza viruses is shown to be similar to the evolution of other swine viruses, presenting evidence it emerged from unsampled herds.

The evolution of H1N1pdm ancestors with other influenza viruses is shown to be similar to the evolution of other swine viruses, presenting evidence it emerged from unsampled herds.
Wild Bird ’ seye View of Influenza Virus A ( H 1 N 1 ) Phylogenetic Evolution
TLDR
The results find that the 2009 H1N1 human outbreak is closely related to swine virus, but falls into different clades in the H1 and N1 trees.

TLDR
In sharp contrast to SARS and Avian Influenza H5N1 viruses which emerged from the Asian continent, Influenza 2009 A/H1N1 virus emerged from North America.
Cluster analysis of the origins of the new influenza A(H1N1) virus.
TLDR
The genetics of the new strain of influenza A(H1N1) virus is studied and it is shown that the new virus combines genetic information related to different swine influenza viruses.

TLDR
A novel swine-origin influenza A virus was identified as the cause of outbreaks of febrile respiratory infection ranging from self-limited to severe illness and it is likely that the number of confirmed cases underestimates thenumber of cases that have occurred.
