Abstract

Phylogenomics of eukaryote supergroups suggest a highly complex last common ancestor of eukaryotes and a key role of mitochondrial endosymbiosis in the origin of eukaryotes.

  • A major event in the evolution of eukaryotes was when organisms capable of engulfing other organisms acquired mitochondria and chloroplasts.

    “Complexity can also occur within cells; a major event in the evolution of eukaryotes was when organisms capable of engulfing other organisms acquired mitochondria (permitting aerobic respiration for energy) and chloroplasts (permitting oxygenic photosynthesis) (Koonin, 2010).”

    From The Astrobiology Primer v2.0 (2016) · cites this paper as Koonin, 2010

    The Eukaryotes and The archaeal and bacterial roots of eukaryotes sections describe mitochondria as widespread in eukaryotes and plastids as an additional organelle in particular lineages. But Eukaryogenesis: where did the eukaryotes come from? rejects the argument that phagocytosis was necessary for mitochondrial acquisition, while The supergroups of eukaryotes and the root of the eukaryotic evolutionary tree places plastid acquisition on the Plantae lineage. The source therefore supports organelle acquisition, not the claim that organisms already capable of engulfing others acquired both as one major event. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
