Some parasites have evolved the ability to precisely control the behavior of animals in ways that enhance the transmission of parasite genes into the next generation. This is the concept of the 'extended phenotype' first conceived by Richard Dawkins in 1982. It states that the behavior we observe in animals is due not only to the expression of their genes, but also to the genes of parasites infecting them. In such cases, the behavior is an extended phenotype of the parasite.
有些寄生虫已经进化出了精确控制动物行为的能力,这种方式可以增强寄生虫基因传递到下一代的效率。这就是理查德·道金斯(Richard Dawkins)在 1982 年首次提出的“延伸表型”概念。它指出,我们在动物身上观察到的行为不仅是它们自身基因表达的结果,还受到感染它们的寄生虫基因的影响。在这种情况下,行为就是寄生虫的延伸表型。
