Benefits of increased size and functional specialization of cells have repeatedly promoted the evolution of multicellular organisms from unicellular ancestors. Many requirements for multicellular organization (cell adhesion, cell-cell communication and coordination, programmed cell death) likely evolved in ancestral unicellular organisms. However, the evolution of multicellular organisms from unicellular ancestors may be opposed by genetic conflicts that arise when mutant cell lineages promote…

Experimental evolution of multicellularity
TLDR
Experimental evolution shows that key aspects of multicellular complexity, a subject of central importance to biology, can readily evolve from unicellular eukaryotes.
Experimental Evolution of Multicellular Complexity in Saccharomyces cerevisiae
TLDR
The origin and subsequent evolution of multicellular complexity in snowflake yeast can be directly attributed to natural selection.

TLDR
It is suggested that the emergence of specialized reproductive cells (the germ line) was an essential first stage of the evolutionary transition to multicellularity because it imposed the necessary "delay" allowing natural selection to operate over the longer timescale of aMulticellular life cycle, ultimately resulting in the evolution of complex multice cellular organisms.
Evolution of simple multicellularity increases environmental complexity
TLDR
It is demonstrated that even in simple conditions, incipient multicellularity readily changes the environment, facilitating the origin and maintenance of diversity.
Multicellularity in animals: The potential for within-organism conflict.
TLDR
It is argued that the prevalence of such organisms throughout the Metazoa requires us to refine the authors' preconceptions of conflict-free multicellularity, and a conceptual overview from evolutionary biology for developmental biologists is provided, using analogous examples in the well-studied social insects.
Evolution of selfish multicellularity collective organisation of individual spatio-temporal regulatory strategies
TLDR
This model demonstrates how emergent selection pressures at the onset of multicellularity can drive the evolution of cellular behaviour to give rise to developmental patterns, as seen in striking patterns of spatio-temporal cell state changes that visually resemble animal development.
High Relatedness Is Necessary and Sufficient to Maintain Multicellularity in Dictyostelium
TLDR
It is concluded that the single-cell bottleneck is a powerful stabilizer of cellular cooperation in multicellular organisms.
Meta-population structure and the evolutionary transition to multicellularity.
TLDR
The results show that the transition to multicellularity benefits from ecological conditions that maintain discreteness not just of the group (soma) phase, but also of the dispersal (germline) phase.
Toward a New Understanding of Multicellularity
TLDR
It is here hypothesized that obligate multicellularity results from extended cooperation between different life entities adopted as a strategy to survive prolonged low-fitness periods.
De novo origins of multicellularity in response to predation
TLDR
It is shown that de novo origins of simple multicellularity can evolve in response to predation, and this results support the hypothesis that selection imposed by predators may have played a role in some origins of multICEllularity.

An evolutionary scenario for the transition to undifferentiated multicellularity
TLDR
It is argued that in populations of unicellular organisms with cooperative behavior, clustering may be beneficial by reducing interactions with noncooperative individuals and presented a set of computer simulations showing that clustering can evolve as a biological, heritable trait for cells that cooperate in the use of external energy resources.

TLDR
The independent instances of multicellularity reviewed indicate that advantages in feeding and in dispersion are common, and the capacity for signaling between cells accompanies the evolution of multICEllularity with cell differentiation.
Cooperation and conflict in the evolution of multicellularity
TLDR
This paper studies conflict mediation, the process by which genetic modifiers evolve that enhance cooperation by altering the parameters of development or rules of formation of cell groups, and is particularly interested in the conditions under which these modifiers lead to a new higher-level unit of selection.

Regular ArticleSize and complexity among multicellular organisms
TLDR
The diversity of specialized cell types (‘complexity’) is estimated for a wide range of multicellular organisms and major groups of organisms differ in complexity at given size: animals are more complex than plants, and phaeophytes are simpler than either.

TLDR
Volvox and its relatives provide an exceptional model for integrative studies of the evolution of multicellularity and cellular differentiation and the proximate causes of this type of evolutionary transition are being studied in V. carteri.
