\caption{Results of the evolutionary analyses for positively selected sites for Mx1 in bats. P-values were achieved by performing chi-squared tests on twice the difference of the computed log likelihood values of the models disallowing (M7) or allowing (M8) $dN/dS>1$. The BEB column lists rapidly evolving sites with a $dN/dS>1$ and a posterior probability $>0.95$, determined by the Bayes Empirical Bayes implemented in \texttt{Codeml}. Amino acids refer to \emph{Myotis daubentonii}. Note that INDELs and the stop codon were removed from the alignment prior to evolutionary analysis, so shown positions are based on the \textbf{alignment without gaps}. Fragments arising from insignificant breakpoints (adjusted p-value $>$ 0.1) are marked with an asterisk.}\\\\
