Plant Signaling & Behavior, 2023 With the appearance of plants and animals, new challenges emerged. These multicellular eukaryotes had to solve for example the difficulties of multifaceted communication between cells and adaptation to new habitats.

BMC Biology, 2021 The volvocine algae, which include the single-celled species Chlamydomonas reinhardtii and the colonial species Volvox carteri, serve as a model in which to study the evolution of multicellularity and cellular differentiation.

Selective advantage for multicellular replicative strategies: A two-cell example [PDF]
, 2005 This paper develops a quasispecies model where cells can adopt a two-cell survival strategy. Within this strategy, pairs of cells join together, at which point one of the cells sacrifices its own replicative ability for the sake of the other cell.

What Do We Mean by Multicellularity? The Evolutionary Transitions Framework Provides Answers
Frontiers in Ecology and Evolution, 2021 The meaning of the word ‘multicellularity’ appears to be unambiguous – a concept that can be grasped with common sense. On closer inspection, however, there is notable disparity in the recent literature regarding the usage of the term ‘multicellularity’,

Characterising the mechanics of cell–cell adhesion in plants
Quantitative Plant Biology, 2022 Cell–cell adhesion is a fundamental feature of multicellular organisms. To ensure multicellular integrity, adhesion needs to be tightly controlled and maintained. In plants, cell–cell adhesion remains poorly understood.

Adaptation to a Viscous Snowball Earth Ocean as a Path to Complex Multicellularity
American Naturalist, 2021 Animals, fungi, and algae with complex multicellular bodies all evolved independently from unicellular ancestors. The early history of these major eukaryotic multicellular clades, if not their origins, co-occur with an extreme phase of global glaciations

Frontiers in Psychology, 2019 All epistemic agents physically consist of parts that must somehow comprise an integrated cognitive self. Biological individuals consist of subunits (organs, cells, and molecular networks) that are themselves complex and competent in their own native ...

Oxygen-sensing mechanisms across eukaryotic kingdoms and their roles in complex multicellularity
Science, 2020 Origins and evolution of hypoxia response In our current oxygen-rich atmosphere, the ability of eukaryotic cells to sense variation in oxygen concentrations is essential for adapting to low-oxygen conditions.

The evolution of convex trade-offs enables the transition towards multicellularity
Nature Communications, 2021 The evolutionary transition towards multicellular life often involves growth in groups of undifferentiated cells followed by differentiation into soma and germ-like cells.

Evolution of multicellularity in Dictyostelia [PDF]
, 2019 The well-orchestrated multicellular life cycle of Dictyostelium discoideum has fascinated biologists for over a century. Self-organisation of its amoebas into aggregates, migrating slugs and fruiting structures by pulsatile cAMP signalling and their ...
