The paper sequenced 200 genomes of Theobroma cacao to show that domestication of the Criollo population occurred around 3,600 years ago, with strong selection on genes related to anthocyanin, theobromine metabolism, and disease resistance, and found a negative correlation between Criollo ancestry and bean yield.
