DESCRIPTION:This talk will describe recent experimental and theoretical ad
 vances in understanding the dynamics and architecture of organisms that se
 rve as models for evolutionary transitions to multicellularity. I will foc
 us on four interrelated subjects: the fluid dynamical and elastic properti
 es of the recently discovered choanoflagellate C. flexa\, which dynamicall
 y interconverts between two hemispherical forms of opposite curvature\, th
 e recent discovery of common probability distributions of cellular neighbo
 urhood volumes in both "snowflake yeast" and the green alga Volvox\, embry
 onic "inversion" and the spontaneous curling of the extracellular matrix o
 f Volvox. Taken together\, these studies shed light on a fundamental quest
 ion: "How do cells produce structures external to themselves in an accurat
 e and robust manner?"
