Abstract

Botanists have long believed that hybrid speciation is important, especially after chromosomal doubling (allopolyploidy). Until recently, hybridization was not thought to play a very constructive part in animal evolution. Now, new genetic evidence suggests that hybrid speciation, even without polyploidy, is more common in plants and also animals than we thought.

摘要

长期以来，植物学家一直认为杂交物种形成很重要，尤其是在染色体加倍（异源多倍体）之后。直到最近，杂交在动物进化中还未被认为发挥着非常重要的建设性作用。现在，新的基因证据表明，即使没有多倍体，杂交物种形成在植物和动物中都比我们想象的更为普遍。
