🔎 We tested alternative rooting hypotheses (e.g., roots at Archaeplastida, Discoba, Metamonada) and found that none were as strongly supported as the Opimoda+/Diphoda+ root. The results hold across multiple models, even after controlling for biases. (5/)

Záhonová et al. tested whether hydrogenosomes and mitosomes in Metamonada originated from an independent endosymbiosis, finding instead that these organelles originated from an Alphaproteobacterium during a single common endosymbiosis.

Understanding phylogenetic relationships among eukaryotic lineages is essential for tracing evolution of key phenotypic traits and inferring nature of the Last Eukaryotic Common Ancestor

Re-evaluating the eukaryotic Tree of Life with independent phylogenomic data🧪
www.biorxiv.org/content/10.6...
Comparison of ML phylogenetic trees based on mutually-exclusive phylogenomic datasets. a) tree based on the Leroy-specific (LS) concatenation (213 markers, 47,217 sites). b) tree based on the Strassert-Tice (ST) concatenation (350 markers, 94,293 sites). Support values on branches correspond to ultrafast bootstrap (UFB) and PMSF non-parametric bootstrap (NPB). Branch lengths for Metamonada were halved for display purposes. The branch of Centroplastelida showed the most dramatic shift in position between the two trees, as indicated by the dashed red line.

i remember making this tree of life thing last year
a simplified tree of life with the major kingdoms, and also major endosymbiotic events indicated not all relationships are as simple as indicated in the tree BACTERIA -themotogati -fusobacteriati -pseudomonadati -bacillati ARCHAEA -nanobdellati -methanobacteriati -thermoproteati -promethearchaeati EUKARYOTA (Excavata; paraphyletic) -discoba -metamonada (uncertain placement) -ancyromonadida -malawimonada -CRuMs / crumalia (?)

there's no way in hell a brown seaweed would be related to a slime mold, let alone the unicellular ancestors of animals
a meme template from star wars: the last jedi where luke skywalker (@markhamillofficial.bsky.social) prepares to burn down the tree of the jedi, but in exploitable meme format where the traditional kingdom "Protista" is broken down into several groups such as: -Metamonada (metamonads) -Discoba (includes Euglena) -Cryptista (cryptomonads) -Haptista (haptophytes) -Rhodophyta (red algae, closely related to the plants) -Glaucophyta (glaucophyte algae, closesly related to the plants; their chloroplasts notably retain a peptidoglycan wall from ancestral cyanobacteria) -Stramenopiles (heterokonts, including water molds, yellow algae, and brown algae such as kelp) -Alveolata (alveolates, which include ciliates like Paramecium, apicomplexans like Plasmodium, and dinoflagellates) -Rhizaria (rhizarians include foraminiferans or forams) -CRuMs (or Crumalia) -Amoebozoa (includes single-celled amoebae such as the model organism Amoeba proteus, as well as slime molds) -Mesomycetozoa (unicellular relatives of animals) -Choanoflagellata (choanoflagellates are the sister group to animals)

"Protozoa" currently doesn't have a unique definition; it's used by different people to mean different things. Some traditionalists (e.g. Cavalier-Smith) define Protozoa as a paraphyletic group containing major protist groups like Amoebozoa, SAR, Metamonada etc.
