Abstract

Humans differ from other animals in many aspects of anatomy, physiology, and behaviour; however, the genotypic basis of most human-specific traits remains unknown. Recent whole-genome comparisons have made it possible to identify genes with elevated rates of amino acid change or divergent expression in humans, and non-coding sequences with accelerated base pair changes. Regulatory alterations may be particularly likely to produce phenotypic effects while preserving viability, and are known to underlie interesting evolutionary differences in other species. Here we identify molecular events particularly likely to produce significant regulatory changes in humans: complete deletion of sequences otherwise highly conserved between chimpanzees and other mammals. We confirm 510 such deletions in humans, which fall almost exclusively in non-coding regions and are enriched near genes involved in steroid hormone signalling and neural function. One deletion removes a sensory vibrissae and penile spine enhancer from the human androgen receptor (AR) gene, a molecular change correlated with anatomical loss of androgen-dependent sensory vibrissae and penile spines in the human lineage. Another deletion removes a forebrain subventricular zone enhancer near the tumour suppressor gene growth arrest and DNA-damage-inducible, gamma (GADD45G), a loss correlated with expansion of specific brain regions in humans. Deletions of tissue-specific enhancers may thus accompany both loss and gain traits in the human lineage, and provide specific examples of the kinds of regulatory alterations and inactivation events long proposed to have an important role in human evolutionary divergence.

  • Changes in conservation of conserved noncoding or nonexonic elements in a subset of lineages are often associated with altered regulatory activity and ultimately phenotypic divergence.

    “Changes in conservation of elements, such as conserved noncoding or nonexonic elements, in a subset of lineages are often associated with altered regulatory activity and ultimately phenotypic divergence”

    From Bayesian Detection of Convergent Rate Changes of Conserved Noncoding Elements on Phylogenetic Trees (2019) · cites this paper as McLean et al. 2011

    The Abstract reports two human-lineage deletions of conserved noncoding enhancers associated with anatomical differences, supporting the proposed link between regulatory change and phenotypic divergence. It does not establish that such changes are often associated with divergence across lineages, and it cautions that the enhancer losses might have followed other genetic changes rather than caused the anatomical differences.

  • Variants of the apo(a) gene highlight the intersection between gene duplication and cardiovascular risk.

    “Others, like variants of the apo(a) gene, highlight the intersection between gene duplication and cardiovascular risk, serving as a striking example of the clinical potential impact of evolutionary research [110].”

    From Origin and Evolution of Genes in Eukaryotes: Mechanisms, Dynamics, and Functional Implications (2025) · cites this paper as [110]

    The supplied passages and searches for apo(a), lipoprotein(a), gene duplication, and cardiovascular risk found no discussion of the claimed connection. The paper instead discusses human-specific losses of regulatory DNA, including enhancers near AR and GADD45g (Abstract; page unavailable). (LLM, conf=0.76)

  • Existing relaxed clock methods are not easily scalable to genome-wide data such as is typically encountered when testing for rate changes in conserved elements across a clade for which whole-genomes have been sequenced.

    “Moreover, although highly accurate and useful for validating various clock models, these methods are not easily scalable to genome-wide data such as is typically encountered when testing for rate changes in conserved elements across a clade for which whole-genomes have been sequenced”

    From Bayesian Detection of Convergent Rate Changes of Conserved Noncoding Elements on Phylogenetic Trees (2019) · cites this paper as McLean et al. 2011

    The Methods Summary describes a genome-wide search for conserved sequences and human-specific deletions, but does not assess relaxed-clock methods or their scalability. Searches for relaxed-clock scalability and rate-change testing across a clade found no passage addressing that claim. The indexed passages provide no page numbers. (LLM, conf=0.76)

  • A systematic search identified 510 human-specific deletions compared with other primate genomes, almost exclusively in noncoding regions.

    “Conversely, a systematic search for human-specific deletions compared with other primate genomes identified 510 such deletions in humans that fall almost exclusively in noncoding regions (McLean et al., 2011).”

    From Genetic Changes Shaping the Human Brain (2015) · cites this paper as McLean et al., 2011

  • One human-specific deletion removes a forebrain germinal zone enhancer near GADD45G, suggesting a possible role in the expansion of specific brain regions in humans.

    “One such deletion removes a forebrain germinal zone enhancer near the tumor suppressor gene growth arrest and DNA-damage-inducible, gamma (GADD45G), suggesting a possible role in the expansion of specific brain regions 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.
