Viral eukaryogenesis is the hypothesis that the cell nucleus of eukaryotic life forms evolved from a large DNA virus in a form of endosymbiosis within a methanogenic archaeon or a bacterium. The virus later evolved into the eukaryotic nucleus by acquiring genes from the host genome and eventually usurping its role.
Nov 1, 2020 · According to the updated Viral Eukaryogenesis (VE) hypothesis presented here, the eukaryotic nucleus descends from the viral factory of a DNA virus that infected the archaeal ancestor of the eukaryotes.

May 10, 2022 · The viral eukaryogenesis (VE) hypothesis proposes that eukaryotes evolved from a viral factory, an archaeal host and a bacterial symbiont. The article challenges the dominant paradigm of a universal ancestor and a universal Tree of Life and argues for a radical rethinking of biological evolution.
May 1, 2023 · The authors argue that the virome of the last eukaryotic common ancestor is bacterial, rather than archaeal, providing support for a syntrophic model of eukaryogenesis with two endosymbiosis...
Mar 12, 2015 · Origin of the major groups of RNA viruses of eukaryotes. The depicted evolutionary reconstruction is predicated on the symbiogenetic scenario of eukaryogenesis. The host ranges of viral groups are color-coded as shown in the inset. Icons of virion structures are shown for selected groups.

Jun 27, 2022 · Rambo is referring to a hotly debated hypothesis called viral eukaryogenesis. It suggests that, in addition to bacteria and archaea, viruses might have contributed some genetic component to the development of eukaryotes.
The evolutionary history of viruses remains unclear. Some researchers hypothesize that viruses evolved from mobile genetic elements that gained the ability to move between cells. Other...
