Developmental lines of least resistance predict standing genetic covariation but do not constrain plasticity or rapid evolution.

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
Some phenotypic dimensions are more developmentally variable than others. Such developmental variability (or bias) is common and uncontroversial. However, how and at what time scales these biases constrain or facilitate the emergence of standing genetic variation, plastic responses, as well as adaptation remains contentious. To investigate the extent to which developmental variability shapes genetic variation, plasticity and evolution, we first quantify developmental variability in the shape of the dung beetle foreleg-a functional trait critical for the excavation of breeding tunnels. We do so by testing how random developmental perturbations, manifesting themselves in fluctuating asymmetry, shape standing genetic variation within populations. Next, we investigate whether such developmental variability is aligned with thermal plasticity and recently evolved latitudinal variation. We find that, while developmental variability is a strong predictor of standing genetic (co)variance (i.e. the
