Natural selection and language genes in humans.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
In this study we construct lists of candidate genes for articulate language. Analysis of coding regions of over 100 candidate genes for the effects of natural selection (directional episodic selection and relaxed/intensified selection) in the various lineages of primates (thirty-four nonhuman primate species, plus Homo sapiens Neanderthals and Denisovans) revealed a burst of altered selection effects on neural genes at the node leading to the Homo sapiens-Neanderthal-Denisova triad, followed by bursts of selection effects on neural genes related to language in both the Denisovan and Neanderthal lineages. Those latter increases in involvement of neural genes in Neanderthals and Denisovans can be contrasted with the missing or slight response to selection on those same genes in the H. sapiens lineage. The genes involved in these bursts can mostly be classified as involved in synapse structure and maintenance. We develop a hypothesis for how synaptic efficiency could be related to language acquisition in these lineages.
