Abstract
The role of hybridization in evolution has been debated for over a century. Recent molecular genetic studies indicate that hybridization is surprisingly frequent in natural populations, and that it may allow populations to regain traits that have been lost and possibly to replace damaged alleles with functional copies from related species.
摘要
杂交在进化中的作用已经争论了一个多世纪。最近的分子遗传学研究表明，杂交在自然种群中出人意料地频繁，而且它可能使种群重新获得已丧失的性状，并有可能用来自相关物种的功能拷贝取代受损的等位基因。
