Detailed genetic maps of three related sunflower species support the view that one species originated relatively recently from the other two by hybrid speciation, providing the first good evidence for this theory of speciation.
三种相关向日葵物种的详细基因图谱支持了这样一种观点，即其中一个物种相对较近地通过杂交物种形成从另外两个物种演化而来，为这种物种形成理论提供了首个有力证据。
