DESCRIPTION:Within the field of Evo-Devo\, great emphasis has been placed 
 on how the gene regulatory networks that pattern embryos evolve over time.
  However\, these networks do not\, by themselves\, give rise to the embryo
 nic form that is eventually exposed to natural selection at the larval/adu
 lt stage. Rather\, this form comes from cell division\, rearrangement and 
 shape changes that drive tissue level changes. Therefore\, in order to und
 erstand how animal form evolves\, we must uncover how the changes in gene 
 regulatory networks that we observe actually effect changes at the morphog
 enetic level. In my seminar\, I will first present some of my own work on 
 the morphogenetic basis of development in the beetle _Tribolium castaneum_
 . This species is particularly well suited for studying morphogenesis as d
 uring early development\, extensive cellular rearrangements and tissue fol
 ding take place. Furthermore\, while these morphogenetic events are conser
 ved in most insects\, they do not take place in the fly _Drosophila melano
 gaster_. After setting the scene with _Tribolium_\, I will present my most
  recent work on the morphogenetic function of _Toll_ genes\, a project tha
 t features findings from seven different species spanning over 500 million
  years of evolution. Lastly\, I will discuss how we can integrate findings
  on the morphogenetic basis of development into what we already know about
  the evolution of embryogenesis.
