Experimental evolution shows that the cooperation of cells in multicellular organisms degrades under low relatedness. Most complex multicellular organisms develop clonally from a single cell. This should limit conflicts between cell lineages that could threaten the extensive cooperation of cells within multicellular bodies. Cellular composition can be manipulated in the social amoeba Dictyostelium discoideum, which allows us to test and confirm the two key predictions of this theory… Expand
Experimental evolution reveals that high relatedness protects multicellular cooperation from cheaters
TLDR
This work allows two variants of the fungus Neurospora crassa to evolve, one with and one without the ability to form chimeras with other individuals, thus generating two relatedness levels, and demonstrates that high genetic relatedness is crucial to sustain multicellular cooperation. Expand
Does high relatedness promote cheater‐free multicellularity in synthetic lifecycles?
TLDR
It is found that manipulating growth and dispersal of clones of a social amoeba to create high levels of relatedness was sufficient to prevent the spread of cheating mutants, and cheaters were able to spread under low‐relatedness conditions. Expand
Experimental evolution of multicellularity using microbial pseudo-organisms
TLDR
An experimental evolution method is proposed, using micro-organisms to construct multicellular pseudo-organisms, which can be evolved under different artificial life cycles, to test how different life cycles favour cooperation, even for life cycles that do not exist. Expand
Origins of multicellular evolvability in snowflake yeast
TLDR
This work demonstrates that simple microev evolutionary changes can have profound macroevolutionary consequences, and suggests that the formation of clonally developing clusters may often be the first step to multicellularity. Expand
Group Formation, Relatedness, and the Evolution of Multicellularity
TLDR
It is found that species with clonal group formation were more likely to have undergone the major evolutionary transition to obligate multicellularity and had more cell types, a higher likelihood of sterile cells, and a trend toward higher numbers of cells in a group. Expand
The multicellularity genes of dictyostelid social amoebas
TLDR
It is concluded that the transition to multicellularity required novel signals and sensors rather than novel signal processing mechanisms, and changes in gene expression correspond more strongly with phenotypic innovation than changes in protein functional domains. Expand
Group Maintenance in Aggregative Multicellularity
TLDR
This work reviews the key mechanisms by which aggregative multicellular organisms control cheaters with a focus on the best studied aggregative organisms, Myxococcus xanthus and Dictyostelium discoideum. Expand
Measuring cheating, fitness, and segregation in Dictyostelium discoideum.
TLDR
Techniques for assaying cheating and segregation in D. discoideum are described, which cover how to grow and maintain cells, fluorescently label genotypes, design experiments for accuracy and precision, calculate fitness and segregation, and interpret the results. Expand
Why have aggregative multicellular organisms stayed simple?
TLDR
Because they primarily exist in a unicellular state, it may be difficult for aggregative multicellular organisms to evolveMulticellular traits that carry pleiotropic cell-level fitness costs, so even in the absence of social conflict, aggregative multi-cellular organisms may have limited potential for the evolution of complex multicesllularity.

The Evolution of Multicellularity: A Minor Major Transition?
TLDR
Benefits of increased size and functional specialization of cells have repeatedly promoted the evolution of multicellular organisms from unicellular ancestors, but these benefits may be opposed by genetic conflicts that arise when mutant cell lineages promote their own increase at the expense of the integrity of the multice cellular organism. Expand
High relatedness maintains multicellular cooperation in a social amoeba by controlling cheater mutants
TLDR
The findings show how altruism is preserved from the disruptive effects of such mutant cheaters and how exceptionally high relatedness among cells is important in promoting the cooperation that underlies multicellular development. Expand
Dictyostelium: Evolution, Cell Biology, and the Development of Multicellularity
TLDR
This chapter discusses the evolutionary biology of Dictyostelium discoideum, its relatives, and the transition from growth to development: from starvation to self sustaining cAMP signal relay. Expand
Kin Discrimination Increases with Genetic Distance in a Social Amoeba
TLDR
It is demonstrated that D. discoideum cells co-aggregate more with genetically similar than dissimilar individuals, suggesting the existence of a mechanism that discerns the degree of genetic similarity between individuals in this social microorganism. Expand
Facultative cheater mutants reveal the genetic complexity of cooperation in social amoebae
TLDR
Findings indicate that phenotypically stable cooperative systems may nevertheless harbour genetic conflicts, and that the opportunities for evolutionary moves and countermoves in such conflicts may select for the involvement of multiple pathways and numerous genes. Expand
Altruism and social cheating in the social amoeba Dictyostelium discoideum
TLDR
Microsatellite markers are used to show that different clones collected from a field population readily mix to form chimaeras, and half of the chimaeric mixtures show a clear cheater and victim. Expand

TLDR
An explicit two locus genetic framework is provided for understanding the evolutionary transition from single cells to multicellular organisms in terms of the increase of cooperation among cells and the regulation of conflict within the emerging organism. Expand

TLDR
The role of kinship is examined, focusing on the transitions to multicellularity in animals and to coloniality in insects, to show that kin selection based on high relatedness permitted cooperation and a reproductive division of labour. Expand
Self-Recognition in Social Amoebae Is Mediated by Allelic Pairs of Tiger Genes
TLDR
It is shown that a matching pair of tgrB1 and tgrC1 alleles is necessary and sufficient for attractive self-recognition, which is mediated by differential cell-cell adhesion, and it is proposed that TgrB 1 and TgrC 1 proteins mediate this adhesion through direct binding. Expand

TLDR
Under optimal conditions, vegetative cell populations harvested from nutrient medium and dispensed homogeneously on a solid substratum can be made to exhibit remarkably consistent morphogenetic behavior in respect to the timing and patterns of aggregation and of fruiting body construction. Expand
