The nucleoprotein (NP) is one of the main determinants of species specificity of influenza A viruses. Using 25 NP sequences we have constructed evolutionary trees by the strict-parsimony procedure of Fitch (197 1). In contrast to the evolutionarygene tree, the tree based on amino acid sequences unravels remarkable differences between avian and human NPs, differences which are best explained by ...

In March and early April 2013, a new Avian-Origin Influenza A (H7N9) Virus (A-OIV) emerged in the eastern China. This virus has caused global concern as a potential pandemic threat. Here we use evolutionary analysis to reconstruct the origins and early development of the A-OIV viruses. We found that A-OIV was derived from a reassortment of three avian flu virus strains, and substantial mutation...

We thank Dr. Lipsitch for his comments (1). Dr. Lipsitch does not argue with the notion that gain-of-function experiments are epistemologically valuable, but he does feel that their practical value is limited. Likewise, we would not argue that reasonable people cannot come to different conclusions about the relative epistemic value of any given experiment. He makes several points to which we wi...
