    • Scaling and shear transformations capture beak shape variation in Darwin's finches 

      Campas, O.; Mallarino, Ricardo; Herrel, A; Abzhanov, Arkhat; Brenner, M (Proceedings of the National Academy of Sciences, 2010)
      Evolution by natural selection has resulted in a remarkable diversity of organism morphologies that has long fascinated scientists and served to establish the first relations among species. Despite the essential role of ...
    • Two developmental modules establish 3D beak-shape variation in Darwin's finches 

      Mallarino, Ricardo; Grant, P. R.; Grant, B. R.; Herrel, Antony; Kuo, W. P.; Abzhanov, Arkhat (Proceedings of the National Academy of Sciences, 2011)
      Bird beaks display tremendous variation in shape and size, which is closely associated with the exploitation of multiple ecological niches and likely played a key role in the diversification of thousands of avian species. ...
