Abstract

Summary: The hologenome theory of evolution emphasizes the role of microorganisms in the evolution of animals and plants. The theory posits that the holobiont (host plus all of its symbiont microbiota) is a unit of selection in evolution. Genetic variation in the holobiont that can occur either in the host and/or in the microbial symbiont genomes (together termed hologenome) can then be transmitted to offspring. In addition to the known modes of variation, i.e. sexual recombination, chromosomal rearrangement and mutation, variation in the holobiont can occur also via two mechanisms that are specific to the hologenome theory: amplification of existing microorganisms and acquisition of novel strains from the environment. These mechanisms are Lamarckian in that (i) they are regulated by ‘use and disuse’ (of microbes) and (ii) the variations in the hologenome are transmitted to offspring, thus satisfying also the Lamarckian principle of ‘inheritance of acquired characteristics’. Accordingly, the hologenome theory incorporates Lamarckian aspects within a Darwinian framework, accentuating both cooperation and competition within the holobiont and with other holobionts.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Behavior that facilitates social interaction among holobionts might be considered evolutionarily adaptive/advantageous because it gives rise to greater transmission of microbiota, thereby enhancing genetic variation.

    “behavior that facilitates social interaction among holobionts might be considered evolutionarily adaptive/advantageous as it gives rise to greater transmission of microbiota, thereby enhancing genetic variation (Rosenberg et al., 2010;Rosenberg et al., 2009;Zilber-Rosenberg and Rosenberg, 2008).”

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.
