A recent study by Cosby et al. sheds light on the role of transposons in the adaptive evolution of their hosts. These genetic elements were thought to be largely deleterious. However, when coupled with alternative splicing, there appears to be an exponential increase in the diversity of proteins encoded, which display novel functions and are conserved by natural selection.
考斯比等人最近的一项研究揭示了转座子在宿主适应性进化中的作用。这些遗传元件以前被认为主要是有害的。然而，当与选择性剪接结合时，编码的蛋白质多样性似乎呈指数级增加，这些蛋白质表现出新颖的功能，并通过自然选择得到保守。
