Domesticated species are valuable models to examine phenotypic evolution, and knowledge on domestication history is critical for understanding the trajectories of evolutionary changes. Sequentially Markov Coalescent models are often used to infer domestication history. However, domestication practices may obscure the signal left by population history, affecting demographic inference. Here we assembled the genomes of a recently domesticated species—the society finch—and its parent species—the white‐rumped munia—to examine its domestication history. We applied genomic analyses to two society finch breeds and white‐rumped munias to test whether domestication of the former resulted from inbreeding or hybridization. The society finch showed longer and more runs of homozygosity and lower genomic heterozygosity than the white‐rumped munia, supporting an inbreeding origin in the former. Blocks …
