None of our early ancestors could digest milk as adults because their bodies never had to ----milk drinking simply wasn’t an option. As people began to extract milk from animals, though, some people developed the ability to keep drinking it throughout their lives.

　　 Scientists now know of a milk-related mutation ( 变异) in our genes -- the chemical instructions for life that we carry in almost every cell in our bodies. People who have a mutated form of one particular gene can drink milk just fine. People without the mutation tend to get sick from milk.

　　 To figure out where, and possibly why, milk drinking started, some scientists have been looking at who has the milk-digesting mutation today. Patterns are striking.

　　 Most adults in Northern and Central Europe are able to digest milk -- and they do. Cheese and butter and other dairy products are popular in countries such as Sweden, Denmark, Germany and England. Because European settlers dominated North America, most people here can handle milk just fine, as well. That may explain why ice cream is such a popular dessert in the United States.

　　 In much of Africa, Asia and South America, on the other hand, people tend to avoid dairy products because they lead to diarrhea (腹泻) and other stomach problems. (That’s why you won’t typically find cheese on the menu at a Chinese, Japanese or Ethiopian restaurant.) Native

Americans are also unable to digest milk.

　　 Based on these genetic patterns, scientists have long thought that- milk drinking started inNorthern Europe, where dairy is an institution and the milk-digesting mutation is everywhere.

　　 A recent study painted a different picture. With a computer medal, Thomas and colleagues looked at the spread of the milk-drinking mutation, farming and other related factor. Working backward, the scientists concluded that the first milk-thinkers lived in Central Europe around what’s now Hungary about 7,500 years ago. The practice didn't start farther north, as scientists had thought before.

In the year 480 BC the Greek allies (联军) faced invasion by the King of Persia, Xerxes, who commanded a huge army of about half a million men. When the Persian army marched into northern Greece, the Greek states, led by Athens and Sparta, were ill equipped to deal with the threat. The Persians were well supplied with food and weapons. Their army included infantry, cavalry, and a large navy. It seemed that they would easily defeat the Greeks.

　　 The Greek allies decided to send 10,000 men northwards to slow down the Persians, while the rest prepared to defend their homelands. A group of 300 best Spartan soldiers were chosen to lead the force going north, with Leonidas in command. Leonidas realized that the only hope of slowing the Persians would be to block the narrow passage of land at Thermopylae. The Pass of

Thermopylae was the route between the mountains and the sea, and was so narrow that only a few men could get through at a time.

　　 When the Persian army arrived at Thermopylae, they found Leonidas' tiny army opposing them. The Persians attacked, but could not get through. They attacked again and again, but each time they were driven back by the Greeks, led by the fearless Spartans. Leonidas' plan worked well until a Greek traitor called Ephialtes went m Xerxes. He told the Persian king about a goat's path in the mountains that would take the Persian army past Thermopylae. When Leonidas saw the enemy crossing the mountains, he realized that he could no longer hold Thermopylae. He sent all the Greek soldiers except the 300 Spartans back to their homelands.

　　 The Spartans waited for the 500,000 Persians at the goat’s path. Although hopelessly outnumbered, the Spartans fought bravely. They all died, but the other Greeks were able to get home to strengthen the defenses.
