“…Multicellularity comes in many forms and complexity levels, ranging from simple cell aggregations, colonies, films or filaments to the most complex organisms known (Szathmary & Smith, ; Rokas, ; Fairclough, Dayel, & King, ; Knoll, ; Niklas & Newman, ; Richter & King, ; Sebé‐Pedrós et al ., ; Niklas, ; Rainey & de Monte, ; Umen, ; Aguilar, Eichwald, & Eberl, ; Herron & Nedelcu, ). While simple cell aggregations and colonies evolved at least 25 times in both pro‐ and eukaryotes (Grosberg & Strathmann, ; Rokas, ), complex multicellularity has evolved in up to five major groups: animals, embryophytes, red and brown algae (Knoll, ; Claessen et al ., ; Niklas, ; Umen, ; Cock et al ., , ; Nagy, ; Niklas & Newman, ; Sebé‐Pedrós, Degnan & Ruiz‐Trillo, ), and fungi.…”
