Contributions

T.H. conceived the idea for the response, conducted the phylogenetic analyses and wrote the manuscript. S.K. helped to write the manuscript. The four other co-authors of the original study1 (Y. Hu, K. Uesugi, M. Hoshino and M. Manabe) did not participate in this Reply, because the subject of this Reply had been developed by T.H. and S.K. in the original study, but all continue to support it.
