"Which came first, the Chicken or the Egg?" We suggest this question is not a paradox. The Modern Synthesis envisions speciation through genetic changes in germ cells via random mutations, an "Egg first" scenario, but perhaps epigenetic inheritance mechanisms can transmit adaptive changes initiated in the soma ("Chicken first").
“先有鸡还是先有蛋？”我们认为这个问题并非悖论。现代综合进化论设想通过生殖细胞中随机突变引起的基因变化来实现物种形成，这是一种“先有蛋”的情形，但也许表观遗传遗传机制可以传递体细胞中起始的适应性变化（“先有鸡”）。
