New #ISEPpapers #preprint by @DEEMteam: Re-evaluating the eukaryotic #TreeOfLife with independent phylogenomic data https://www.biorxiv.org/content/10.64898/2026.04.08.717153v1.abstract

"analyses confirm most eukaryotic supergroups previously observed, but suggest different positions for some lineages. Notably, Telonemia clusters with Haptophyta rather than SAR, and Ancyromonadida and Malawimonadida form a monophyletic group at the base of the Opimoda."

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 tiny pantheon known as the Asgard archaea bear traits that hint at how plants, animals and fungi emerged on Earth.

"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."
