Speciation is a fundamental process shaping biodiversity. However, existing empirical methods often cannot provide key genetic and functional details required to validate speciation theory. New gene modification technologies can verify the causal functionality of genes with astonishing accuracy, helping resolve questions about how reproductive isolation evolves during speciation.

功能基因组学提供了物种假设的新检验。

物种形成是塑造生物多样性的基本过程。但是，现有的经验方法通常无法提供验证物种形成理论所需的关键遗传和功能细节。新的基因修饰技术可以惊人的准确性验证基因的因果功能，有助于解决有关物种形成过程中生殖分离如何演变的问题。
