Thank you for sharing my publication! For readers, I introduce some new hot papers in the field of fin-to-limb evolution after publishing my article. # My review article about morphological differences between fin and limb is here; Yano and Tamura, J. Anat. (2013) http://dx.doi.org/10.1111/j.1469-7580.2012.01491.x # Hoxd13 is important for appendage evolution; Freitas et al, Dev. Cell (2012) http://dx.doi.org/10.1016/j.devcel.2012.10.015 # These researches are referred by Schneider and Shubin, Trends Genet. (2013) http://dx.doi.org/10.1016/j.tig.2013.01.012 # Do you know the importance about developmental origins of the fin skeleton from the point of view of evolution?; Shimada et al, Nat. Commun. (2013) http://dx.doi.org/10.1038/ncomms2643
