Evolution of altruistic cooperation among nascent multicellular organisms

Abstract: Cooperation is a classic solution to hostile environments that limit individual survival. In extreme cases this may lead to the evolution of new types of biological individuals (e.g., eusocial super‐organisms). We examined the potential for interindividual cooperation to evolve via experimental evolution, challenging nascent multicellular “snowflake yeast” with an environment in which solitary multicellular clusters experienced low survival. In response, snowflake yeast evolved to form cooperative groups compo… Show more

“…New levels of organization emerge when natural selection favors cooperation and the loss of conflict between previously autonomous replicating entities, giving rise to a collective unit upon which selection can further operate ( Michod et al, 2006 ; West et al, 2015 ; Queller and Strassmann, 2009 ). Cooperation thus underlies the evolution of larger, more complex biological systems ( Fisher and Regenberg, 2019 ; Gulli et al, 2019 ; Michod et al, 2006 ; West et al, 2015 ; Hammerschmidt et al, 2014 ). However, because cooperators incur the near-term cost of contributing to the fitness of others for long-term benefit, cooperation creates opportunities for the emergence of selfish ‘cheater’ entities, which show up at multiple levels of the hierarchy of biological organization.…”

“…Cooperation and cheating represent conflicting adaptive strategies understood to shape the evolution and behavior of complex biological systems (Fisher and Regenberg, 2019, Gulli et al, 2019, Michod et al, 2006, West et al, 2015, Hammerschmidt et al, 2014). In particular, transitions toward larger, more complex forms of life occur when natural selection favors cooperation and loss of conflict between individual life forms, enabling them to become integrated into a collective entity that replicates and undergoes selection as a unified whole (Michod et al, 2006, West et al, 2015, Queller and Strassmann, 2009).…”

“…For instance, on the order of 25 independent origins of Eukaryotic multicellularity are known (Grosberg and Strathmann, 2007) with most transitions having occurred hundreds of millions of years ago (Libby and Ratcliff, 2014). Recent work in experimental evolution (Koschwanez et al, 2013;Ratcliff and Travisano, 2014;Ratcliff et al, 2015;Gulli et al, 2019), mechanistic modeling (Hanschen et al, 2015;Staps et al, 2019), and digital evolution (Goldsby et al, 2012(Goldsby et al, , 2014 complements traditional post hoc approaches focused on characterizing the record of natural history. These systems each instantiate the evolutionary transition process, allowing targeted manipulations to test hypotheses about the requisites, mechanisms, and evolutionary consequences of fraternal transitions.…”
