Multicellular organisms appear to have arisen from unicells numerous times. Multicellular cyanobacteria arose early in the history of life on Earth. Multicellular forms have since arisen independently in each of the kingdoms and several times in some phyla. If the step from unicellular to multicellular life was taken early and frequently, the selective advantage of multicellularity may be large. By comparing the properties of a multicellular organism with those of its putative unicellular…

The Evolution of Multicellularity: A Minor Major Transition?

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.

De novo origins of multicellularity in response to predation

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.

Selective drivers of simple multicellularity.

A survey of recent developments in systematics, comparative biology, paleontology, synthetic biology, theory, and experimental evolution highlights the many ecological opportunities available for simple multicellularity, and stresses the need for additional work examining how these first steps impact the subsequent evolution of complex multICEllularity.

The origin of multicellularity in cyanobacteria

Comparison to the fossil record supports an early origin of multicellularity, possibly as early as the "Great Oxygenation Event" that occurred 2.45 - 2.22 billion years ago.

Understanding “green” multicellularity: do seaweeds hold the key?

The molecular mechanisms by which organisms become multicellular are not well understood, and how to increase the future understanding is discussed.

Evolution of Multicellularity

The transition from a unicellular to a multicellular life-style constitutes a transition in individuality, a process whereby a group of previously independent individuals become stably integrated into a new functional, physiological and reproductively autonomous and indivisible evolutionary unit.

An evolutionary scenario for the transition to undifferentiated multicellularity

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.



The Evolution of Soma in the Volvocales

The allometry of soma and germ supports the idea that soma functions to provide functional flagella during the embryogenesis of large colonies (Volvocaceae), and suggests that the cell wall is a preadaptation for the evolution of large multicellular colonies with deterministic development.

Heterocyst pattern formation controlled by a diffusible peptide.

Overexpression of a 54-base-pair gene, patS, blocked heterocyst differentiation in Anabaena sp.

Cyanobacterial Phylogeny and Development: Questions and Challenges

Although the most clearly differentiated cells are heterocysts and akinetes, there is increasing evidence for more subtle forms of differentiation in at least two genera, Trichodesmium and Cliroococcidiopsis.

Cell alignment required in differentiation of Myxococcus xanthus.

It is proposed that directed cell movement establishes critical contacts between adjacent cells, which are required for efficient intercellular C-factor transmission during fruiting body morphogenesis of Myxococcus xanthus.

Myxobacteria: A Most Peculiar Group of Social Prokaryotes

This chapter shall discuss the myxobacteria in a more general framework, and most of the morphogenetic studies and all of the genetics have been carried out on one particular organism, Myxococcus xanthus, so that this book will deal mainly with that species.

The Paleobiologic Record of Cyanobacterial Evolution

This chapter considers one of the broadest questions of microbial evolutionary development, namely, what does the paleobiological record suggest about the tempo and mode of prokaryotic, especially cyanobacterial evolution, as well as biotic interactions with long-term environmental change and the physiology and biochemistry of ancient fife.

Pattern formation in the blue-green alga, Anabaena. I. Basic mechanisms.

An interactive model for pattern formation in Anabaena is proposed, where a pattern consisting of groups of consecutive proheterocysts is seen which resolves into a normal discrete pattern.

Evolutionary relationships among cyanobacteria and green chloroplasts

The results indicate that many diverse forms of cyanobacteria diverged within a short span of evolutionary distance and suggest that the chloroplast lineage, which includes the cyanelle of C. paradoxa, is not just a sister group to the free-living forms but rather is contained within the cyanobacterial radiation.

Endospore-Forming Bacteria: an Overview

The classical and strict distinction between aerobic and anaerobic spore formers no longer holds; it is now known that, given the right environment, Bacillus subtilis and other Bacillus species can grow quite well anaerobically.

Developmental cheating in the social bacterium Myxococcus xanthus

It is shown that social cheating exists even among prokaryotes, with clones from several evolved lines and two defined mutants exhibited cheating during development, being over-represented among resulting spores relative to their initial frequency in the mixture.
