Proposal: Origin of Eukaryotes Is Symbiosis of Not One But Two Bacteria and an Archeon

December 3, 2020, Purificación López-García and David Moreira submitted a paper, The Syntrophy hypothesis for the origin of eukaryotes revisited, published in Nature Microbiology, in which they proposed a symbiosis of two bacteria and an archeon as the origin of eukaryotes. I found their proposal utterly convincing and highly recommend a reading of it with a mind to including it in Wikipedia's article, Symbiogenesis.

Added. The article needs further work now to distinguish current from historic hypotheses; but concepts specific to eukaryogenesis should really be in that article, rather than here which is covering symbiogenesis of all kinds and at all periods. Chiswick Chap (talk) 11:29, 21 May 2023 (UTC)

To add to what the Chap said, this article very much needs updating with recent findings regarding the Asgard archaea. In just the past few years, genomic studies of this archaean group have produced broad scientific consensus that eukaryotes originated from symbiosis between an Asgard archaean and an alphaproteobacteria. The alphaproteobacterial origin of mitochondria has been known a long time and is well-described here. The Asgard archaean origin of the eukaryotic cell is a recent discovery and is almost entirely absent. 2019 paper presents some of the central findings of this discovery.

Um, I repeat: the origin of the Eukaryotes is Eukaryogenesis --- NOT the subject of this article. And my username is CC, thanks. Chiswick Chap (talk) 07:20, 9 April 2024 (UTC)

Nitroplasts

How should the proposed nitroplasts be represented in this article?

On the basis of one primary research paper? Cautiously, minimally, likely not at all until independent confirmation arrives? Chiswick Chap (talk) 07:01, 19 April 2024 (UTC)

Cryptic. The article doesn't even name the original paper, but I've found it and added a brief section. Chiswick Chap (talk) 05:57, 28 April 2024 (UTC)

Usage of "gya" in article image

The term "gya" is used in the article's first image but it is not defined. It don't think it should be assumed that the reader has this knowledge that "gya" refers to gigayears ago.

The term "gya" should be replaced by "Gigayears ago", or at the very least it should be replaced by "Gya" with correct capitalisation to represent the actual metric prefix. ~2026-21725-42 (talk) 14:34, 8 April 2026 (UTC)
