Copy-cat evolution: Divergence and convergence within and between cat and dog breeds.
Article in Proceedings of the National Academy of Sciences of the United States of America, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Many domesticated species exhibit remarkable phenotypic diversity. In nature, selection produces not only divergence but also convergence when organisms experience similar selective pressures. Whether artificial selection during domestication also produces convergence has received little attention. Three-dimensional shape analysis of domestic cat and dog skulls demonstrated convergence at multiple levels. Most broadly, cats and dogs have both diversified greatly: equaling or exceeding the morphological disparity among all modern-day species of their respective families. Moreover, as a result of artificial selection, some breeds of these two phenotypically distinct species, evolutionarily separated for 50 My, have converged to such an extreme extent that they are more similar to each other than they are to many members of their own species or their ancestors, a phenomenon never previously observed in domesticated species. Remarkably, this convergence evolved not only between dogs and cats but also multiple times within each taxon.
