10.15 Harnessing natural diversity to discover the rules of flower color evolution

By Stacey Dewitt Smith, Department of Ecology and Evolutionary Biology, University of Colorado, Boulder (Homepage)

Abstract

One of the most striking aspects of the angiosperm 
radiation is their diversity of flower colors. In this talk, I will 
explore the mechanisms by which flower colors evolve and examine the 
relationship between micro- and macroevolution of color.  Work in my 
group and others points to a high degree of convergence in the genetic 
and developmental mechanisms that lead to flower color transitions among 
lineages. Within species variation in flower color arises by diverse and 
often distinct mechanisms, pointing to a challenge in relating the 
commonly observed color morphs within species to macroevolutionary 
transitions.

11.00 Possible bias toward micro- and macroevolutionary conservation by 
developmental systems
