A recurrent regulatory change underlying altered expression and Wnt response of the stickleback armor plates gene EDA.

abstract：:The loss of previously adaptive traits is typically linked to relaxation in selection, yet the molecular steps leading to such repeated losses are rarely known. Molecular studies of loss have tended to focus on gene sequences alone, but overlooking other aspects of protein expression might underestimate phenotypic div...
