Next time you have a glass of milk...think of these KB's:

Overview:
Although it is nearly impossible to pinpoint, most historians believe that using milk as a beverage began about 10,000 years ago when animals were first domesticated. Evidence suggests that this early domestication appeared first in Afghanistan and Iran, then later in Turkey and some areas in Africa. Plymouth Rock colonists brought cattle to America in the 1600s and within 200 years dairies produced large quantities of milk for market in large cities. The 20th century brought new technologies to milk production resulting in safer dairy products worldwide.
