Initial sequence of the chimpanzee genome and comparison with the human genome

Abstract

Here we present a draft genome sequence of the common chimpanzee (Pan troglodytes). Through comparison with the human genome, we have generated a largely complete catalogue of the genetic differences that have accumulated since the human and chimpanzee species diverged from our common ancestor, constituting approximately thirty-five million single-nucleotide changes, five million insertion/deletion events, and various chromosomal rearrangements. We use this catalogue to explore the magnitude and regional variation of mutational forces shaping these two genomes, and the strength of positive and negative selection acting on their genes. In particular, we find that the patterns of evolution in human and chimpanzee protein-coding genes are highly correlated and dominated by the fixation of neutral and slightly deleterious alleles. We also use the chimpanzee genome as an outgroup to investigate human population genetics and identify signatures of selective sweeps in recent human evolution.

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

  • 3.5% of the sequence differences between chimpanzees and humans is due to INDELs.

    “It has been estimated that 3.5% of the sequence differences between chimpanzees and humans is due to INDELs [34,35] and that this INDEL variation may be of particular evolutionary significance [9].”

    From Identification, characterization and comparative genomics of chimpanzee endogenous retroviruses (2006) · cites this paper as [34]

    The Nucleotide divergence section estimates that indel differences span approximately 3% of both genomes, compared with 1.23% from nucleotide substitutions. That is a percentage of genome sequence, not a finding that indels account for 3.5% of the differences between the genomes; the paper says indels affect more bases than substitutions. (LLM, conf=0.88)

    Checked by a reasoning model — may be wrong.

  • Frequent turnover of gene copy and/or protein domain number has been proposed as a major mechanism underlying the adaptive divergence of closely related species.

    “Frequent turnover of gene copy and/or protein domain number has been proposed as a major mechanism underlying the adaptive divergence of closely related species 9,[17][18][19] .”

    From The yak genome and adaptation to life at high altitude (2012) · cites this paper as [9]

    The gene-evolution discussion (page unavailable in our copy) describes gene-family expansion, recent human-specific duplications, and genes deleted in chimpanzees, supporting the gene-copy-change portion of the claim. It does not identify turnover of protein-domain number or propose that these changes are a major mechanism of adaptive divergence. (LLM, conf=0.77)

    Experimental — accuracy not yet measured
  • Genomic comparisons between closely related species provide insights into the genetic basis of mammalian divergence and adaptation.

    “Genomic comparisons between closely related species provide insights into the genetic basis of mammalian divergence and adaptation 8,9 .”

    From The yak genome and adaptation to life at high altitude (2012) · cites this paper as [9]

  • Yak and cattle were estimated to have diverged approximately 4.9 million years ago, comparable to the time at which humans and chimpanzees diverged.

    “Yak and cattle were estimated to have diverged approximately 4.9 million years ago, which is comparable to the time at which humans and chimpanzees diverged 9 (Supplementary Fig. 12).”

    From The yak genome and adaptation to life at high altitude (2012) · cites this paper as [9]

  • The number of endogenous retroviruses in chimpanzees may be higher than in humans.

    “results presented here and elsewhere [34] suggest that the number of endogenous retroviruses in chimpanzees may be higher than in humans.”

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.
