Palaeogenomics suggest domesticated camelid herding and wild camelid hunting in early pastoralist societies in the Atacama Desert.
Article in Nature communications, 2025. 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
The domestication of camelids played a significant role in the development of Andean societies. However, distinguishing wild from domesticated forms remains difficult due to overlapping morphology. We use palaeogenomics to reveal the sex and ancestry of camelids from the Tulán ravine, a key region for early pastoral development in the South-Central Andes. We find evidence for both Vicugna and Lama based on 49 individuals with >0.001x coverage. Investigations into 26 individuals >0.01x show all individuals, except one male Lama, represent ancestry not in modern individuals. Similar male-to-female sex ratios suggest hunting or herding with selective culling. We find limited evidence for intergeneric admixture common in modern domesticates. Here, we show that early Formative communities (3360-2370 cal. yr BP) in the Tulán ravine primarily exploited wild or now-extinct early domesticate lineages, indicating that present-day domestic camelids are not direct descendants of those managed by early pastoralists.
