水平基因转移被认为是调节原核生物基因组进化的重要进化力量。然而，人们认为水平基因转移在后生动物进化中只发挥次要作用。在本文中，我批判性地回顾了有关水平转移基因和后生动物新性状获得的不断增加的证据。我特别讨论了海绵、刺胞动物、轮虫、线虫、软体动物和节肢动物中的可疑例子，这些例子表明后生动物中的水平基因转移不仅仅是一种好奇心。此外，我强调脊椎动物和其他动物群体研究的稀缺性以及即将进行的研究的重要性，以了解动物水平基因转移的重要性和程度。
Horizontal gene transfer is accepted as an important evolutionary force modulating the evolution of prokaryote genomes. However, it is thought that horizontal gene transfer plays only a minor role in metazoan evolution. In this paper, I critically review the rising evidence on horizontally transferred genes and on the acquisition of novel traits in metazoans. In particular, I discuss suspected examples in sponges, cnidarians, rotifers, nematodes, molluscs and arthropods which suggest that horizontal gene transfer in metazoans is not simply a curiosity. In addition, I stress the scarcity of studies in vertebrates and other animal groups and the importance of forthcoming studies to understand the importance and extent of horizontal gene transfer in animals.
