Here, we investigated the domestication of African yam (Dioscorea rotundata), a key crop in early African agriculture. Using whole-genome resequencing and statistical models, we show that cultivated yam was domesticated from a forest species. We infer that the expansion of African yam agriculture started in the Niger River basin. This result, along-side with the origins of African rice and pearl millet, supports the hypothesis that the vicinity of the Niger River was a major cradle of African agriculture. specialized AFRIQUE DE L'OUEST COTE D’IVOIRE GHANA TOGO BENIN NIGERIA CAMEROUN 076 5 5 eaaw1947 [7 p.] 2019 2375-2548 https://www.documentation.ird.fr/hor/fdi:010076071 10.1126/sciadv.aaw1947 2375-2548 [F B010076071] https://www.documentation.ird.fr/hor/fdi:010076071 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers19-06/010076071.pdf IRD - Base Horizon / Pleins textes 2019-07-05 2025-02-24 fdi:010076071 fre
