Is a net growth advantage necessary for #multicellularity? We often assume groups must outperform single cells locally. But @ctarnita & colleagues show that spatial heterogeneity can drive this transition via indirect benefits www.nature.com/articles/s41...

An exceptionally detailed #molecular explanation of how clonal #multicellularity, where all cells descend from a single ancestor, can be achieved and controlled at the #genetic level.

Scientists found five single-celled organisms that might hold the key to how life became multicellular — not fully evolved, but sometimes they form colonies.
At least amoebas aren’t stuck anxiously waiting for Stranger Things to return.
Evolution just vibes.

Hourglass model of complex multicellularity found in brown algae https://phys.org/news/2024-10-hourglass-complex-multicellularity-brown-algae.html paper: https://www.nature.com/articles/s41586-024-08059-8
"Complex #multicellularity evolved independently in various eukaryotic lineages, including #animals, #plants, #fungi, and #algae... According to the hourglass model of embryonic development, early and late stages of development exhibit morphological and molecular diversity, while a mid-embryonic phase remains highly conserved across species."

We are family: Tracing the #evolution of animals https://knowablemagazine.org/content/article/living-world/2024/evolution-of-multicelled-life
"To understand the origins of muticelled life, researchers are studying a motley assortment of simpler animal relatives. The commonalities they’re unearthing offer a trove of clues about our mutual past... Researchers speculate that something major must have happened in the world to make teaming up such a good deal. It must be environmental, to a large degree"

"As seawater gets colder, it grows thicker. It’s basic physics — the density and viscosity of water molecules rises as the temperature drops. Under the conditions of Snowball Earth, the ocean would have been twice or even four times as viscous as it was before the planet froze over. Simpson wondered what it would have been like to be a microscopic organism in the ocean during Snowball Earth."

"By testing a series of alternative—& commonly debated—hypotheses, we demonstrate how #multicellularity was likely acquired differently in #eukaryotes & #prokaryotes owing to selective differences on their size due to the biophysical & #metabolic regimes they inhabit: decreasing temperatures... instigated by the onset of glaciations generated selective pressures towards smaller sizes in organisms in the diffusive regime & towards larger sizes in motile heterotrophs"

Origins of #Multicellularity Revisited https://schaechter.asmblog.org/schaechter/2024/02/origins-of-multicellularity-revisited.html @STCmicrobeblog
"How can we get over the notion, still apparently widely held, that #bacteria are largely unicellular and #eukaryotes mostly multicellular? Our teaching should emphasize that facultative #multicellularity evolved very early, that it might even be intrinsic to the origin of life"
