Scientists have long known more about breeding herds of female elephants, said Connie Allen, a biologist at the University of Exeter in Britain.

英国埃克塞特大学的生物学家康妮·艾伦说，科学家早就对母象群的繁殖有了更多的了解。

In other cultures, we have taken this mastery a step further, taming and breeding the wild herds, making them docile and easy to handle.

在其他文明中，这种对于牧群的驾驭又上了一个台阶，我们可以驯服并培育野生牧群让它们更加易于掌控。
