Gene expression and digit homology in the chicken embryo wing

Summary The bird wing is of special interest to students of homology and avian evolution. Fossil and developmental data give conflicting indications of digit homology if a pentadactyl “archetype” is assumed. Morphological signs of a vestigial digit I are seen in bird embryos, but no digit‐like struc...
