Now, researchers have used the genomes of over 200 donkeys to trace their domestication back to a single event around 7,000 years ago in East Africa - about 3,000 years before humans tamed horses.
现在，研究人员利用了200多匹驴的基因组，追溯它们的驯化历史，发现大约在7000年前的东非发生了一次单一的驯化事件——这比人类驯化马早了约3000年。
The team reconstructed the animals' evolutionary tree and used computer models to pinpoint the domestication event, when herders in Kenya and the Horn of Africa tamed wild asses.
该团队重建了这些动物的进化树，并利用计算机模型确定了驯化事件，即大约在肯尼亚和非洲之角的牧民驯服了野驴。
But understanding where the animals were first domesticated could guide archaeologists to a narrower region to search for insights about the original tamed donkeys.
但是了解动物最初在哪里被驯化，可能会引导考古学家在更狭窄的区域内寻找关于最初被驯化的驴的见解。
They were tamed at an earlier time than horses.
它们比马更早被驯化。
