Of two contending models for eukaryotic evolution the “archezoan“ has an amitochondriate eukaryote take up an endosymbiont, while “symbiogenesis“ states that an Archaeon became a eukaryote as the result of this uptake. If so, organelle formation resulting from new engulfments is simplified by the primordial symbiogenesis, and less informative regarding the bacterium‐to‐mitochondrion conversion. Gradualist archezoan visions still permeate evolutionary thinking, but are much less likely than… Expand
Debating Eukaryogenesis—Part 2: How Anachronistic Reasoning Can Lure Us into Inventing Intermediates
  • D. Speijer
  • Biology, Medicine
  • BioEssays : news and reviews in molecular, cellular and developmental biology
  • 2020
TLDR
It is posited that a symbiotic stage before uptake (“pre‐symbiosis”) seems essential to allow further metabolic integration of the two partners ending in endosymbiosis, and argued against phagocytic mechanisms (in which the bacterium is prey or parasite) as the mode of entry. Expand
Debating Eukaryogenesis—Part 1: Does Eukaryogenesis Presuppose Symbiosis Before Uptake?
  • D. Speijer
  • Medicine, History
  • BioEssays : news and reviews in molecular, cellular and developmental biology
  • 2020
TLDR
The author argues that such models share flaws, hence making them less likely, and that a “pre‐symbiotic stage” would have eased ongoing metabolic integration, and speculated about the nature of the (endo) symbiosis that started eukaryotic evolution. Expand
Comparing Early Eukaryotic Integration of Mitochondria and Chloroplasts in the Light of Internal ROS Challenges: Timing is of the Essence
TLDR
Differences between organellar ribosomes, changes to the electron transport chain (ETC) components, and mitochondrial codon reassignments in nonplant mitochondria can be understood when mitochondrial ROS formation, e.g., during high energy consumption in heterotrophs, is taken into account. Expand
Physiology, anaerobes, and the origin of mitosing cells 50 years on.
  • W. Martin

  • 2017
TLDR
The 1967 paper presented an appealing narrative that linked the origin of mitochondria with oxygen in Earth history: cyanobacteria make oxygen, oxygen starts accumulating in the atmosphere about 2.4 billion years ago, oxygen begets oxygen-respiring bacteria that become mitochondria via symbiosis, followed by later (numerous) multiple, independent symbioses involving cyanob bacteria that brought photosynthesis to eukaryotes.

Alternating terminal electron‐acceptors at the basis of symbiogenesis: How oxygen ignited eukaryotic evolution
  • D. Speijer
  • Biology, Medicine
  • BioEssays : news and reviews in molecular, cellular and developmental biology
  • 2017
TLDR
This work hypothesizes that conditions favouring bacterial uptake were based on exchange of intermediate carbohydrate metabolites required by recurring changes in availability and use of the two different terminal electron chain acceptors, the bacterial one being oxygen. Expand
In defence of the three-domains of life paradigm
TLDR
The three-domain Model of life represents an accurate description of the differences at the most fundamental level of living organisms, as the eukaryotic lineage that arose from this unique merging event is distinct from both Archaea and Bacteria in a myriad of crucial ways. Expand
How oxygen gave rise to eukaryotic sex
TLDR
It is proposed that the crucial determinant can be found in internal reactive oxygen species (ROS) formation at the start of eukaryotic evolution approximately 2 × 109 years ago and that this alternative to mitosis is crucial under novel, ROS-producing stress situations. Expand
What can we infer about the origin of sex in early eukaryotes?

  • Biology, Medicine

  • 2016
TLDR
Current analysis shows that the last eukaryotic common ancestor (LECA) was capable of full meiotic sex, consistent with the likely development of fullmeiotic sex from a diverse set of existing archaeal repair and signalling mechanisms. Expand
Mitochondria, the Cell Cycle, and the Origin of Sex via a Syncytial Eukaryote Common Ancestor
TLDR
The origin of mitochondria was the origin of vertical lineage inheritance, and sex was required to keep vertically evolving lineages viable by rescuing the incipient eukaryotic lineage from Muller’s ratchet. Expand
The Physiology of Phagocytosis in the Context of Mitochondrial Origin
TLDR
The physiology and components of phagocytosis in eukaryotes are reviewed, critically inspecting the concept of a phagotrophic host, which would have had great physiological benefit for a mitochondrion-bearing cell. Expand

TLDR
Phylogenetic evidence is presented that primitively amitochondriate eukaryotes containing the nucleus, cytoskeleton, and endomembrane system may have never existed, and sequential, or converging, global events could fill the gap between prokaryotes and eUKaryotes known as major evolutionary discontinuity.

TLDR
The apparent ubiquity of mitochondrial homologues bears testament to the importance of the mitochondrial endosymbiosis, perhaps as a founding event, in eukaryotic evolution. Expand
From archaeon to eukaryote: the evolutionary dark ages of the eukaryotic cell.
TLDR
A new model is proposed, the 'PhAT (phagocytosing archaeon theory)', which explains the emergence of the cellular and genomic features of eukaryotes in the light of a transiently complex phagocyrifying archaeon. Expand
Endosymbiotic gene transfer from prokaryotic pangenomes: Inherited chimerism in eukaryotes
TLDR
It is reasoned that the endosymbiotic ancestors of mitochondria and chloroplasts brought into the eukaryotic—and plant and algal—lineage a genome-sized sample of genes from the proteobacterial and cyanobacterial pangenomes of their respective day and that, even if molecular phylogeny were artifact-free, sampling prokaryotic panganomes through endosYmbiotic gene transfer would lead to inherited chimerism. Expand
Eukaryogenesis, how special really?
TLDR
Overall, it is questioned whether premises of existing theories about the uniqueness of eukaryogenesis and the greater evolutionary potential of eUKaryotes have been objectively formulated and whether, despite widespread acceptance that eukarianogenesis was “special,” any such notion has more than rhetorical value. Expand
The Common Ancestor of Archaea and Eukarya Was Not an Archaeon
TLDR
It is suggested that the ancestors of archaea (and bacteria) escaped protoeukaryotic predators by invading high temperature biotopes, triggering their reductive evolution toward the “prokaryotic” phenotype (the thermoreduction hypothesis) and it was suggested that their last common ancestor was more complex than modern archaea but simpler than modern eukaryotes. Expand
On the last common ancestor and early evolution of eukaryotes: reconstructing the history of mitochondrial ribosomes.
TLDR
It is inferred that LECA possessed a mitochondrial ribosome that was already much larger than its bacterial ancestor, with 19 additional specific proteins, indicating that a certain amount of time occurred between initial endosymbiosis at the origin of the mitochondrion and the diversification of present-day eukaryotic supergroups. Expand
The Genome of Naegleria gruberi Illuminates Early Eukaryotic Versatility
TLDR
The Naegleria genome facilitates substantially broader phylogenomic comparisons of free-living eukaryotes than previously possible, allowing us to identify thousands of genes likely present in the pan-eukaryotic ancestor, with 40% likely eukARYotic inventions. Expand
Endosymbiotic theories for eukaryote origin
TLDR
A survey of endosymbiotic theories for theorigin of eukaryotes and mitochondria, and for the origin of the eukARYotic nucleus, summarizing the essentials of each and contrasting some of their predictions to the observations is compiled. Expand

TLDR
This model effectively represents a synthesis of previous, contending mitochondrial origin hypotheses, with the bulk of the mitochondrial proteome (much of the NPC) having an endogenous origin and the minority component (the APC) having a xenogenous origin. Expand
