Aggregative Multicellularity Evolved Independently in the Eukaryotic Supergroup Rhizaria
Multicellular forms of life have evolved many times, independently giving rise to a diversity of organisms such as animals, plants, and fungi that together comprise the visible biosphere. Yet multicellular life is far more widespread among eukaryotes than just these three lineages. A particularly common form of multicellularity is a social aggregative fruiting lifestyle whereby individual cells...
متن کاملRegulated aggregative multicellularity in a close unicellular relative of metazoa
The evolution of metazoans from their unicellular ancestors was one of the most important events in the history of life. However, the cellular and genetic changes that ultimately led to the evolution of multicellularity are not known. In this study, we describe an aggregative multicellular stage in the protist Capsaspora owczarzaki, a close unicellular relative of metazoans. Remarkably, transit...
متن کاملThe twilight of Heliozoa and rise of Rhizaria, an emerging supergroup of amoeboid eukaryotes.
Recent molecular phylogenetic studies revealed the extraordinary diversity of single-celled eukaryotes. However, the proper assessment of this diversity and accurate reconstruction of the eukaryote phylogeny are still impeded by the lack of molecular data for some major groups of easily identifiable and cultivable protists. Among them, amoeboid eukaryotes have been notably absent from molecular...
متن کاملThe Evolution of Aggregative Multicellularity and Cell–Cell Communication in the Dictyostelia
Aggregative multicellularity, resulting in formation of a spore-bearing fruiting body, evolved at least six times independently amongst both eukaryotes and prokaryotes. Amongst eukaryotes, this form of multicellularity is mainly studied in the social amoeba Dictyostelium discoideum. In this review, we summarise trends in the evolution of cell-type specialisation and behavioural complexity in th...
متن کاملRhizaria
Have you ever stumbled across Ernst Haeckel's stunning 19th century art prints representing complex symmetrical forms that look like snowflakes, armored knights, or even futuristic space stations? Or maybe walking down an indo-pacific beach, you have taken a closer look at the warm sand only to realize that the 'sand' is really countless, minute earthly stars? Chances are you did not realize it...
