Answers to questions on cows 



1. Prehistoric animals related to our cattle were domesticated by the 

 Swiss Lake Dwellers. These cattle existed in rather large numbers down 

 to historic times and were the ancestors of our domestic breeds of the 

 present day. The two kinds of domestic cattle that exist to-day are 

 our own cattle as we know them as separate breeds in Europe and America, 

 and the humped zebu of the eastern countries of the globe. The humped 

 zebu was domesticated in Egypt two thousand years before the Christian 

 Era.
