Single-cell adaptations shape evolutionary transitions to multicellularity in green algae
Nature Ecology & Evolution, 2023 This study shows that environmental conditions promote multicellular group formation in green algae and that retention of daughter cells reliant on nitrogen availability promotes fitness in the lab and in natural lake systems in Sweden.

Division of labor promotes the entrenchment of multicellularity
bioRxiv, 2023 Simple multicellularity evolves readily in diverse unicellular species, but nascent multicellular groups are prone to reversion to unicellularity.

Evolution of Multicellularity [PDF]
Genes, 2021 The emergence of multicellular organisms was, perhaps, the most spectacular of the major transitions during the evolutionary history of life on this planet [...]

Genes, 2021 Multicellular eukaryotes are characterized by an expanded extracellular matrix (ECM) with a diversified composition. The ECM is involved in determining tissue texture, screening cells from the outside medium, development, and innate immunity, all of ...

Multicellularity in animals: The potential for within-organism conflict
Proceedings of the National Academy of Sciences of the United States of America, 2022 Metazoans function as individual organisms but also as “colonies” of cells whose single-celled ancestors lived and reproduced independently. Insights from evolutionary biology about multicellular group formation help us understand the behavior of cells ...

Biophysical Reviews, 2022 The diversity of multicellular organisms is, in large part, due to the fact that multicellularity has independently evolved many times. Nonetheless, multicellular organisms all share a universal biophysical trait: cells are attached to each other.

Experimental evolution is not just for model organisms.
PLoS Biology, 2022 In a new paper published in PLOS Biology, Dudin and colleagues evolve simple multicellularity in Sphaeroforma arctica, a unicellular relative of animals. This work establishes a new and open-ended avenue for examining the evolution of multicellularity in

Oxygen suppression of macroscopic multicellularity
Nature Communications, 2021 Atmospheric oxygen is thought to have played a vital role in the evolution of large, complex multicellular organisms. Challenging the prevailing theory, we show that the transition from an anaerobic to an aerobic world can strongly suppress the evolution

Analysis of motility in multicellular Chlamydomonas reinhardtii evolved under predation. [PDF]
PLoS ONE, 2018 The advent of multicellularity was a watershed event in the history of life, yet the transition from unicellularity to multicellularity is not well understood.
