Laurie Winn Carlson is the author of Cattle: An Informal Social History.
 
"It appears that domestication of cattle began about 8000 years ago in three separate locations.One location is Mesopotamia, and another was in Indus River Valley, and the third location now is believed to be Africa."
 
Mesopotamia:美索不达米亚(或“两河流域”)
Indus River Valley:印度河谷
 
From these centers, domestication spread across Eurasia and throughout Africa.
 
Eurasia:亚欧大陆
 
All over the planet, there were hundreds of potential choices for domestication. But it was the cow that became early man's most important ally as the hunter-gatherer lifestyle gradually settled into agriculture.
 
What made the cow so special? On the plains of East Africa, where earliest men first hunted, we can still see what our ancestors were up against. The criteria 8 for domestication is uncompromising. Very few species would pass muster 9.
 
up against:面临，面对（问题、困难等）
uncompromising:严格得不容商量的
pass muster:合格，达到要求
 
If an animal is too flighty or depends on mass migration 10 for survival, it fails; if it cannot breed in captivity 11, it fails; if it grows too slowly or too large, it fails; if its diet or the conditions it needs are too specialized 12 to recreate, it fails; if it is too aggressive, it fails.
 
flighty:性格不稳定的
 
The cow passed all these exacting 13 tests to become the most important member of a very exclusive club— the domesticates 15. Our ancestors chose wisely and there had been very few additions to their original list of animal allies.
 
exacting:苛刻的
domesticate 14: 驯养动物
 
"It seems that cattle’s herd 16 behavior is what made them so suitable for domestication, because they like to stay in a group, they seek solace 17 in the group when they stay together. And by then following their self-selected leader for where they choose to go, it’s been easy for man to take that place, and to become imprimitive as the leader of the herd.
 
On the other hand, animals that are quite nervous, they have nervous temperament 18 and exhibit a fright response. When man appears, they just jump and run. And there is no chance for interaction. So it was that pause that cattle have, that curiosity, the security that they have within, the herd, they feel very secure when they are all together. So they don't up and run and run off. So it gives that chance for man and cattle to bond."
 
In every new relationship there are new responsibilities, but who exactly was in charge? Man or cow? Although the cow pulled the plough, man, too, was set to work.
