The tracks found at New Mexico’s White Sands National Park are turning upside down past assumptions on when humans first came into North and South America. They look like they were left behind just moments ago by a barefoot teen visitor to New Mexico’s White Sands National Park, each footprint freshly defined (描出外形) by sand. But this is no tourist track. These footprints are among the oldest evidence of humans in the Americas, marking the latest addition to a growing body of evidence that challenges when and how people first got into this unexplored land.
According to the research team, the footprints were pressed into the mua near an ancient lake at White Sands between 21, 000 and 23, 000 years ago, a time when many scientists think that huge ice sheets walled off human passage into North America.
Exactly when humans populated the Americas has been heatedly debated for nearly a century, and until recently, many scientists insisted that this first occurred no earlier than 13, 000 years ago. A growing number of discoveries suggest people were in North and South America thousands of years before. These include the Monte Verde site in Chile that is as old as 18, 500 years and the Gault site in Texas that is up to 20,000 years old. But each find kicks up a firestorm of controversy among scientists.
While the White Sands discovery doesn’t close the book on these debates, it is stirring excitement. “A discovery like this is very close to finding the Holy Grail (圣杯),” says Ciprian Ardelean, an archacologist at the Chiquihuite Cave in Mexico, where researchers believe they have evidence for human activity in the Americas as early as 30,000 years ago.
If confirmed, the discovery of people in the Americas during the last glacial maximum (末次盛冰期)would require a major change in scientifie thinking about how people arrived in the New Werld.

6 . Until recently, several lines of evidence — from fossils genetics, and archaeology — suggested that humans first moved from Africa into Eurasia (the land of Europe and Asia) about 60,000 years ago, quickly replacing other early human species, such as Neanderthals and Denisovans, that they may have met along the way.
However, a series of recent discoveries, including 100,000-year-old human teeth found in a cave in China, have clouded this straightforward statement. And the latest find, a prehistoric jawbone at the Misliya Cave in Israel dating back to nearly 200,000 years ago, which is almost twice as old as any Homo sapiens (智人) remains discovered outside Africa, where our species was thought to have originated from, has added new and unexpected twist.
The find suggests that there were multiple waves of migration across Europe and Asia and could also mean that modern humans in the Middle East were interacting, and possibly mating, with other human species for tens of thousands of years. “Misliya breaks the mould (模式) of existing assumptions of the timing of the first known Homo sapiens in these regions,” said Chris Stringer, head of human origins at the Natural History Museum in London. “It’s important in removing long-lasting-constraint (限制) on our thinking.”
Prof. Hershkovitz, who led the work at Tel Aviv University said, “What Misliya tells us is that modern humans left Africa not 100,000 years ago, but 200,000 years ago. This is revolution in the way we understand the evolution of our own species.” He also added that the record now indicates that humans probably travelled beyond the African continent whenever the climate allowed it. “I don’t believe there was one big departure from Africa,” he said. “I think that throughout hundreds of thousands of years humans were coming in and out of Africa all the time.”
The discovery means that modern humans were potentially meeting and interacting during a longer period with other ancient human groups, providing more opportunity for cultural and biological exchanges. It also raises interesting questions about the fate of the earliest modern human pioneers. Genetic data from modern-day populations around the world strongly suggest that everyone outside Africa can trace their ancestors back to a group that left around 60,000 years ago. So, the inhabitants of the Misliya Cave are probably not the ancestors of anyone alive today, and scientists can only guess why their branch of the family tree came to an end.

All the calculations were led to the same conclusion only if you put the sun there did the movements of the other planets make sense. The problem arises because astronomers had noticed that some planets appeared brighter at time and less bright at others. Between 1510 and 1514 Copernicus worked on his new theory, gradual improving it until it was complete. Then he showed it privately for his friends. They encouraged him to publish his ideas, and Copernicus was cautious. He published it as he lay died in 1543. Her theory is now the basis on what all the ideas of universe are built
Before the 1830s, most newspapers were sold through yearly subscriptions(订阅) in America, usually $ 8 to $ 10 a year. Today $ 8 or $ 10 seems a small amount of money, but at that time the amounts were unaffordable to most citizens. Accordingly, newspapers were read almost only by rich people in politics or the trades. In addition, most newspapers had little in them that would appeal to a large audience. They were dull and visually unpleasant. But the revolution that was taking place in the 1830s would change all that.
The trend, then, was toward the “penny paper”---a term referring to papers made widely available to the public. It meant any inexpensive newspaper; perhaps more importantly it meant newspapers that could be bought in single copies on the street.
This development did not take place overnight. It had been possible(but not easy) to buy single copies of newspapers before 1830, but this usually meant the reader had to go down to the printer’s office to buy a copy. Street sales were almost unknown. However, within a few years street sales of newspapers would be commonplace in eastern cities. At first the price of single copy was seldom a penny ---usually two or three cents was charged --- and some of the older well-known papers charged five or six cents. But the phrase “penny paper” caught the public’s fancy soon there would be papers that did indeed sell for only a penny.
This new trend of newspapers for “the man on the street” did not begin well. Some of the early ventures(企业)were immediate failures. Publishers already in business, people who were owners of successful papers, had little desire to change the tradition. It took a few youthful and daring businessmen to get the ball rolling.
