      "excerpt": "Although the coincidence of contrasting population-genetic patterns with environmental differences is consistent with the known biological function of the OSCA/CSC1-like gene, the present data do not distinguish among alternative evolutionary mechanisms underlying the broader genomic region. Similar patterns may arise through balancing selection, directional selection, demographic history, ancestral polymorphism, historical introgression, or local structural variation. Consequently, we conservatively interpret the chromosome 6A OSCA region as a candidate adaptive genomic interval exhibiting a distinctive population-genetic signature rather than as definitive evidence for any specific mode of selection.",
