This paper aims to explain the transition to multicellularity as a consequence of the evolutionary response to stress. The proposed model is composed of three parts. The first part details stochastic biochemical kinetics within a reactor (potentially compartmentalized). where kinetic rates are influenced by random stress parameters. https://www.roneverhart.com/100-Percent-Sunglasses-SPEEDCRAFT-LE-Money-Mike-HiPER-Silver-Mirror/
