Symposium "Cell-Cell Signaling Drives the Evolution of Complex Traits"
Organized by: John S. Torday



The global concept of this symposium is that cell-cell signaling has 'driven' the vertical integration of vertebrate evolution. Among the principle vertebrate organs and systems there is a direct relationship between cell signaling and structure-function relationships in development, homeostasis, repair and aging. These mechanisms become progressively more derivative over evolutionary time, as the selection pressure becomes one for the interrelationships between organs- respiration and metabolism, metabolism and photoreception, respiration as Radical Oxygen Species and signal transduction. The speakers will address these hierarchical interrelationships in their models and mechanisms of choice.
