Eukaryotes first: how could that be?

  title={Eukaryotes first: how could that be?},
  author={Carlos Mariscal and W. Doolittle},
  journal={Philosophical Transactions of the Royal Society B: Biological Sciences},
In the half century since the formulation of the prokaryote : eukaryote dichotomy, many authors have proposed that the former evolved from something resembling the latter, in defiance of common (and possibly common sense) views. In such ‘eukaryotes first’ (EF) scenarios, the last universal common ancestor is imagined to have possessed significantly many of the complex characteristics of contemporary eukaryotes, as relics of an earlier ‘progenotic’ period or RNA world. Bacteria and Archaea thus… Expand

Figures and Topics from this paper

Critique of the latest evolutionary models of the beginning of life
I figure 1, we see one of the latest trees of life.1 The tree is split into three main domains: Bacteria, Archaea, and Eukarya. Archaea was discovered as a separate domain by Carl Woese whoExpand
Domain Cell Theory supports the independent evolution of the Eukarya, Bacteria and Archaea and the Nuclear Compartment Commonality hypothesis
How simple the NuCom hypothesis is in explaining eukaryote evolution relative to the other hypotheses is discussed and the philosophical importance of simplicity and its relationship to truth in hypotheses such as NuCom and Domain Cell Theory is presented. Expand
Eukaryote specific folds: Part of the whole
Structural superfamilies and folds originating from an eukaryotic stem seem to represent accessory parts that have contributed in the expansion of several prokaryotic processes to a new level of complexity. Expand
How Likely Are We? Evolution of Organismal Complexity
All complex multicellular organisms are eukaryotes. How did the evolution of the highly complex architecture of the eukaryotic cell arise? I discuss the differences between bacteria and archaeaExpand
Life before LUCA.
We see the last universal common ancestor of all living organisms, or LUCA, at the evolutionary separation of the Archaea from the Eubacteria, and before the symbiotic event believed to have led toExpand
Symbiosis: Why Was the Transition from Microbial Prokaryotes to Eukaryotic Organisms a Cosmic Gigayear Event?
It is predicted that examination of the higher order structure of many Archaeal and bacterial genomes might lead to an understanding of what innovations were necessary for eukaryogenesis, when they came about, and whether they were delayed or accelerated by specific events during the Precambrian. Expand
The last universal common ancestor between ancient Earth chemistry and the onset of genetics
This paper argues that a different view of LUCA is needed, one that fits well with the harsh geochemical setting of early Earth and resembles the biology of prokaryotes that today inhabit the Earth's crust. Expand
Evolution: Two Domains of Life or Three?
Eukarya arose from well within Archaea and are specifically related to newly discovered archaeal species with eukaryote-like features. Expand
Changing ideas about eukaryotic origins
  • T. A. Williams, T. Embley
  • Biology, Medicine
  • Philosophical Transactions of the Royal Society B: Biological Sciences
  • 2015
The papers in this theme issue discuss recent progress on the origin of eukaryotic cells and genomes, highlight some of the ongoing debates, and suggest possible routes to future progress. Expand
Akaryotes and Eukaryotes are independent descendants of a universal common ancestor.
It is concluded that the independent descent of Eukaryotes and Akaryotes (archaea and bacteria) from the universal common ancestor (UCA) is the most probable as well as the most parsimonious hypothesis for the evolutionary origins of extant genomes. Expand


Early evolution: prokaryotes, the new kids on the block.
It is argued here that the ribosome (together with the RNAs involved in its assembly) is so large that it must have had a prior function before protein synthesis, which can explain many steps in the origin of life while accounting for the observation that eukaryotes have retained more vestiges of the RNA world. Expand
Complex archaea that bridge the gap between prokaryotes and eukaryotes
The discovery of ‘Lokiarchaeota’ is described, a novel candidate archaeal phylum which forms a monophyletic group with eukaryotes in phylogenomic analyses, and whose genomes encode an expanded repertoire of eUKaryotic signature proteins that are suggestive of sophisticated membrane remodelling capabilities. Expand
Eukaryogenesis, how special really?
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
Time for a change
Comparisons of RNA and DNA sequences now render this model of life's origins obsolete, even misleading, and it is time to drop the term prokaryote, says Norman Pace. Expand
From archaeon to eukaryote: the evolutionary dark ages of the eukaryotic cell.
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
Bacteria with a eukaryotic touch: A glimpse of ancient evolution?
Two landmark papers seem to strengthen the opinion that the “nucleus” of G. obscuriglobus should, one way or another, testify as some sort of evolutionary link between Planctomycetes and modern eukaryotes. Expand
An archaeal origin of eukaryotes supports only two primary domains of life
These results provide support for only two primary domains of life—Archaea and Bacteria—because eukaryotes arose through partnership between them. Expand
The Relative Ages of Eukaryotes and Akaryotes
The Last Eukaryote Common Ancestor (LECA) appears to have the genetics required for meiosis, mitosis, nucleus and nuclear substructures, an exon/intron gene structure, spliceosomes, many centres ofExpand
The Common Ancestor of Archaea and Eukarya Was Not an Archaeon
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.

On the origin of prokaryotes.

It is proposed that certain features of very early evolution which have been eliminated from prokaryotes may survive in eukaryotes, and this would require a careful re-evaluation of the assumptions underlying use of some sequence data to construct phylogenetic trees. Expand
