歌声的多样性是自然选择、性选择和个体学习相互作用的结果。要理解歌曲的多样性，所有这三个因素必须综合考虑，而不是单独考虑。孟加拉雀大约在250年前被驯化。它们的求偶歌曲已经变得与它们的祖先白腰文鸟不同。孟加拉雀唱歌时具有复杂的音符到音符的过渡模式，并且具有声学上不同的音符，而白腰鸟唱歌时具有固定的音符序列，并且大多是宽带音符。孟加拉雀被选择驯化是基于它们良好的养育能力，而不是它们的歌声，但这种人工选择仍然影响了它们的歌声。为了测试是否分歧不仅发生在歌曲表型，但也在应变特定的歌曲学习的易感性的遗传基础，我们进行了交叉培养实验孟加拉雀和白腰Munias之间。在这两个菌株，歌曲学习的影响，饲养条件：声学特征和过渡模式，继养父。然而，歌曲学习的准确性之间的野生和驯化的菌株不同：在芬奇的儿子和导师之间的歌曲音符的共享不是很准确，无论导师，而穆尼亚是高度准确的复制穆尼亚歌曲，但往往省略了歌曲元素芬奇父亲。这些结果表明，白腰鸟强烈约束学习自己的应变的歌曲，而这种约束是放松的孟加拉雀驯化。
Song diversity results from the interactions between natural selection, sexual selection, and individual learning. To understand song diversity, all three factors must be considered collectively, not separately. Bengalese Finches were domesticated about 250 yr ago. Their courtship songs have become different from their ancestor, the White-rumped Munia. Bengalese Finches sing songs with complex note-to-note transition patterns and with acoustically diverse song notes while White-rumped Munias sing songs with fixed note sequence and mostly broad band song notes. Bengalese Finches were selected for domestication based on their good parenting ability, not their songs, but this artificial selection has nonetheless affected their songs. To test whether divergence occurred not only in the song phenotypes but also in the genetic basis for predisposition of strain specific song learning, we conducted a cross-fostering experiment between Bengalese Finches and White-rumped Munias. In both strains, song learning was affected by rearing condition: the acoustical feature and transition patterns followed those of the foster fathers. However, the accuracy of song learning differed between the wild and the domesticated strains: sharing of song note between sons and tutors in Finches was not very accurate regardless of the tutor, while Munias were highly accurate in copying Munia songs but often omitted song elements from Finch fathers. These results suggest that White-rumped Munias are strongly constrained to learn their own strain’s song, and that this constraint was relaxed in the Bengalese Finch by domestication.
