DESCRIPTION:The wing patterns of butterflies provide wonderful opportuniti
 es for establishing an integrative view of morphological diversification. 
 The development of scale-covered wings\, their structural and pigment comp
 lexity and an elaborate patterning system are key evolutionary innovations
  of the Lepidoptera. Wing patterns are fantastically diverse\, both within
  and between species and\, in a number of taxa\, shown to be under strong 
 natural and sexual selection. Moreover\, Lepidoptera wing patterns are exp
 erimentally tractable. Developing wings are large\, accessible through dev
 elopment\, and the shape of the developing wing maps directly onto the adu
 lt wing. As a result\, there is perhaps no better animal system where the 
 transitions from genes\, through developmental pathways\, to phenotype\, f
 unction\, and fitness can be so clearly illuminated. \n\nIn this talk\, I 
 will highlight some recent work in neotropical Heliconius butterflies\, wh
 ich is getting directly at the mechanisms of phenotypic change. This resea
 rch leverages the stunning natural diversity within the group and genomic 
 and functional genomic technologies to understand how morphological variat
 ion is created through development and modified by natural selection withi
 n the context of an extraordinary adaptive radiation.\n
