    • Closely related bird species demonstrate flexibility between beak morphology and underlying developmental programs 

      Mallarino, Ricardo; Campas, O.; Fritz, Joerg; Burns, K. J.; Weeks, Olivia Grace; Brenner, Michael P.; Abzhanov, Arkhat (Proceedings of the National Academy of Sciences, 2012)
      The astonishing variation in the shape and size of bird beaks reflects a wide range of dietary specializations that played an important role in avian diversification. Among Darwin's finches, ground finches (Geospiza spp.) ...
    • Developmental mechanisms of stripe patterns in rodents 

      Mallarino, Ricardo; Henegar, Corneliu; Mirasierra, Mercedes; Manceau, Marie; Schradin, Carsten; Vallejo, Mario; Beronja, Slobodan; Barsh, Gregory S.; Hoekstra, Hopi E. (Springer Nature, 2016)
      Mammalian color patterns are among the most recognizable characters found in nature and can have a profound impact on fitness. However, little is known about the mechanisms underlying their formation and subsequent evolution. ...
    • The Developmental Role of Agouti in Color Pattern Evolution 

      Manceau, Marie; Domingues, Vera S.; Mallarino, Ricardo; Hoekstra, Hopi E. (American Association for the Advancement of Science (AAAS), 2011)
      Animal color patterns can affect fitness in the wild; however, little is known about the mechanisms that control their formation and subsequent evolution. We took advantage of two locally camouflaged populations of Peromyscus ...
    • Paths Less Traveled: Evo-Devo Approaches to Investigating Animal Morphological Evolution 

      Mallarino, Ricardo; Abzhanov, Arkhat (Annual Reviews, 2012)
      One of the chief aims of modern biology is to understand the causes and mechanisms of morphological evolution. Multicellular animals display a stunning diversity of shapes and sizes of their bodies and individual suborganismal ...
    • 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. ...
