How our #cells evolved: #Genome analysis rewrites the origin of the first #eukaryotes
Using the MareNostrum supercomputer, researchers at BSC-CNS and IRB Barcelona discover that the first complex cells emerged from a gradual, millions-year alliance involving giant #viruses and multiple bacterial groups -

How our #cells evolved: #Genome analysis rewrites the origin of the first #eukaryotes
Using the MareNostrum supercomputer, researchers at BSC-CNS and IRB Barcelona discover that the first complex cells emerged from a gradual, millions-year alliance involving giant #viruses and multiple bacterial groups -
The earliest known #eukaryotes, the ancestors of all complex #life on Earth, lived in oxygenated, shallow marine environments nearly 1.7 billion years ago.
The earliest eukaryotes for which we have #fossils lived in predominantly near-shore, oxygenated, benthic (on the seafloor) settings.
This implies that the availability of #oxygen was dictating eukaryote #evolution from its early stages.

How #Microbes Got Their Crawl
#Prokaryotes arose more than four billion years ago. #Eukaryotes emerged much later, somewhere between 2.5 and two billion years ago. How complex eukaryotes evolved from simpler prokaryotes has left scientists scratching their heads for decades.
In the oceans and on land, scientists are discovering rare, transitional organisms that bridge the gap between Earth’s simplest cells and today’s complex ones.

Every once in awhile I catch up on the state of knowledge about really early evolution and there's at least one phylogeny where you have to hunt for the eukaryotes

`Through genome-wide CRISPR screening, we identified the RNA-binding protein DHX29 as a critical regulator of codon-dependent gene expression. Cryogenic electron microscopy and selective ribosome profiling demonstrated that DHX29 directly interacts with the A-site entrance of the translating 80S ribosome... These findings establish a mechanistic link between synonymous codon usage and the regulation of gene expression.`

How these strange #cells may explain the origin of complex life
Asgard archaea bear traits that hint at how #eukaryotes emerged
#Archaea: single-celled organisms that look much like bacteria. 10ya, new group called #AsgardArchaea was identified in sediments from Atlantic. Nothing like us: They live mostly in places with little or no oxygen, and almost unbelievably ancient, perhaps 3B yr. Yet their #DNA shows they are close to humans on tree of life

"The rise of the eukaryotes was one of the most important events in Earth’s history. If it had not occurred, there would be no great white sharks, no towering redwood trees, no hovering hummingbirds and no people. Just slimy layers of bacteria and archaea, everywhere. And the Asgard archaea may have started it all."

Complex #life began to develop earlier, and over a longer span of time, than previously believed.
Nee findings indicate that complex organisms evolved long before there were substantial levels of #oxygen in the #atmosphere, something which had previously been considered a prerequisite to the #evolution of complex life.
The #earth is approximately 4.5 billion years old, with the first #microbial life forms appearing over 4 billion years ago.
These organisms consisted of two groups – #bacteria and the distinct but related #archaea, collectively known as #prokaryotes.
Prokaryotes were the only form of life on earth for hundreds of millions of years, until more complex eukaryotic cells including organisms such as #algae, #fungi, #plants and #animals evolved.
Previous ideas on how and when early prokaryotes transformed into complex #eukaryotes has largely been in the realm of speculation. Estimates have spanned a billion years, as no intermediate forms exist and definitive fossil evidence has been lacking.
By collecting evidence from multiple #gene families in multiple biological systems and focusing on the features which distinguish eukaryotes from prokaryotes, researchers were able to begin to piece together the developmental pathway for complex life.
They obtained evidence that the transition began almost 2.9 billion years ago – almost a billion years earlier than by some other estimates – suggesting that the nucleus and other internal structures appear to have evolved significantly before #mitochondria.
The process of cumulative complexification seems to have taken place over a much longer time period than previously thought.

Giant, #Ancient Life Form Doesn’t Fit Into Any Known Branch of Life
Scientists have debated where #Prototaxites belong in tree of life for over a century, but now a new study suggests it might represent a whole new branch.
Researchers analyzed #fossil of Prototaxites species called Prototaxites taiti and concluded that it belonged to now-extinct lineage of multicellular #terrestrial #eukaryotes (organisms, including all animals and plants, whose cells contain a nucleus).

The origin of the eukaryotic cell corresponded to the most significant increase in #complexity in the history of #life's evolution on Earth.
The billions of years that have passed since the fusion of an #archaea and a #bacteria have resulted in a lack of evolutionary intermediates in the phylogenetic tree until the emergence of the #eukaryotes.
Now researchers present theoretical and observational evidence that a phase transition in genetic complexity was involved.

Prototaxites represents the first giant organisms to live on the terrestrial surface, reaching sizes of 8 metres in the Early Devonian.
It was an extinct lineage of #multicellular terrestrial #eukaryotes.
Assignments to groups of multicellular algae or land plants have been repeatedly ruled out leaving two major alternatives: #Prototaxites was either a #fungus or a now entirely extinct lineage.
The latter hypothesis seems more plausible based on nrw evidence.

Fungi are eukaryotes, meaning their cells have a defined nucleus containing their genetic material. Unlike prokaryotes (such as bacteria), fungi also have other membrane-bound organelles like mitochondria and endoplasmic reticulum. This makes them more complex than prokaryotes at the cellular level. Fungi include organisms like mushrooms, yeasts, and molds, which play essential roles in ecosystems as decomposers. 🍄 #Fungi #Eukaryotes #Science #Biology https://fungiape.com/is-fungi-prokaryote-or-eukaryote/

#biology #eukaryotes #choanoflagellates #Salpingoeca #SalpingoecaRosetta
An article published in the journal "Science Advances" reports the results of a study on microbes of the species Salpingoeca rosetta that offers evidence that individuals exchange electrical signals they use to coordinate their behaviors. Jeffrey Colgren and Pawel Burkhardt used a newly developed genetic tool to examine the behaviors of colonies of these choanoflagellates (Choanoflagellata).

I already knew about #mitochondria, their maternal inheritance and of course their evolutionary roots. That we are on cell-level actually part #bacteria. But watching this, I'm wondering if we as #humans (and almost all #eukaryotes) are not just very complicated vehicles for the survival of these bacteria. 😱
