Nicole King, University of California, Berkeley, The origin of animal multicellularity Many of the genes for cell adhesion and cell-cell signaling evolved before the transition to multicellularity. Originally involved in capturing prey? Now in holding cells together? Colony formation: single cell … Continue reading →
