Narrator: Since the two capuchino species are so genetically similar, Turbek's team essentially was searching for needles in a haystack.

旁白：由于这两个 capuchino 物种在基因上非常相似，Turbek 的团队基本上是大海捞针。

The capuchino seedeaters are distributed throughout South America, and they don't appear to have any clear geographic barriers that prevent them from exchanging genes.

capuchino seedeaters 分布在整个南美洲，它们似乎没有任何明显的地理障碍来阻止它们交换基因。

Both capuchino species responded most aggressively to the song and plumage of their own species, and less aggressively when the song or plumage belonged to the other species.
