Such displays may have become "obsolete" as a signal to peahens, the team proposed in Animal Behaviour.
炫耀斑点数量对于雌孔雀来说似乎已经“过时”了——Dakin等在《动物行为》中指出。
He later came up with sexual selection: Gaudy peacocks please peahens and pass on their genes.
不久之后，他又提出了性择理论：雄孔雀通过尾屏取悦雌孔雀，从而传递自己的基因。
"It certainly looks like a threshold, " Dakin says, although she doesn't have data on whether individual peahens have a response threshold.
“这看起来很像个阈值。”Dakin说，虽然她还没有数据能说明雌孔雀是否也有响应阈值。
Peacocks are more beautiful than peahens.
雄孔雀要比雌孔雀漂亮。
The plumage of peacocks attracts peahens. The stag's antlers are there to fight off other stags. And so on.
雄孔雀的羽毛能吸引雌孔雀、雄鹿的鹿角则是用来击退其它雄鹿。
