1 . An individual from an unknown hominid (原始人类) species walked across a field of wet, volcanic ash in what is now East Africa around 3.66 million years ago, leaving behind a handful of footprints.
Those five ancient footprints, largely ignored since they were partly unearthed at Tanzania’s Laetoli site in 1976, show features of upright walking by a hominid, a new study finds. Researchers had previously considered them hard to classify, possibly produced by a young bear that took a few steps while standing. But the latest analysis refutes that suggestion.
McNutt, DeSilva, who started the new investigation as a Dartmouth College graduate student, and their colleagues fully dug out and cleaned the five Laetoli footprints in June 2019. Then they measured, photographed and 3-D scanned the ancient tracks. McNutt’s group focused on two footprints that were particularly well-preserved. Foot shapes, sizes, and walking characteristics of the Laetoli individual differed in various ways from those of other hominid individuals at the same site. The prints also didn’t match those from modern black bears and modern chimps (黑猩猩) walking upright.
The Laetoli individual possessed a wider, more chimplike foot than humans, the researchers say. Its big toe stuck out slightly from the second toe (脚趾), but not to the degree observed in chimps. On one step, the Laetoli individual’s left leg crossed in front of the right leg, leaving a left footprint directly in front of the previous track. People may cross-step in this way when trying to regain balance. And bears and chimps assume a relatively wide standing due to knee and other bone arrangements that prevent them from walking like the Laetoli individual and probably from cross-stepping, the scientists say.
Given that only two of the ancient footprints are complete enough to analyze thoroughly, the possibility that a chimp other than a hominid made the Laetoli footprints can’t be ruled out, says William Harcourt Smith, a scientist at Lehman College. But evidence of cross-stepping is enough to prove that it was a hominid track maker, he says.

The history of painting in China is long or full of masterpieces from different ages when have their own unique styles.
Truly artistic paintings other than calligraphy (书法) came into exist during the Qin Dynasty and matured in the Wei and Jin periods. It were in the Tang Dynasty that it developed more quicklier than any other previous period. An art continued to advance during the Song and Yuan Dynasties with an increased focus such subjects as mountains and animals. Traditional painting techniques lasted until the end of the Qing Dynasty, when modern painting techniques started off to challenge the traditional one. Although modern paintings had been heavily influenced by the West, they still value traditional painting techniques.

7 . It was December 25, 1914, only 5 months into World War Ⅰ. German, British, and French soldiers already sick and tired of the senseless killing, disobeyed their superiors and fraternized (打得火热) with “the enemy” along two-thirds of the Western Front. German troops held Christmas trees up out of the trenches (战壕) with signs, “Merry Christmas.”
“You no shoot, we no shoot.” Thousands of troops streamed across a no-man’s land filled with dead bodies. They sang Christmas carols, exchanged photographs of loved ones back home, shared rations, played football, and even roasted some pigs. Soldiers embraced (拥抱) men they had been trying to kill a few short hours before. They agreed to warn each other if the Generals (将军) forced them to fire their weapons, and to aim high.
It shocked the high command on either side. Here was disaster in the making: soldiers declaring their brotherhood with each other and refusing to fight. Generals on both sides declared this peacemaking to be wrong. Fifteen million would be killed.
Not many people have heard the story of the Christmas Truce. On Christmas Day, 1988, a story in the Boston Globe mentioned that a local FM radio host played “Christmas in the Trenches” several times and was surprised by the effect. The song became the most requested recording during the holidays in Boston on several FM stations. “Some callers even telephone the host deeply moved, sometimes in tears, asking, ‘What the hell did I just hear?’”
You can probably guess why the callers were in tears. The Christmas Truce story goes against most of what we have been taught about people. It gives us a glimpse of the world as we wish it could be and says, “This really happened once.” It reminds us of those thoughts we keep hidden away, ou of range of the TV and newspaper stories that tell us how trivial (微不足道的) and mean human life is. It is like hearing that our deepest wishes really are true: the world really could be different.

8 . Discoveries at the famous Sanxingdui ruins in Southwest China show that the region’s ancient Shu Kingdom Civilization shared similarities with the Maya.
The Sanxingdui ruins belonged to the Shu Kingdom that existed at least 4,800 years ago and lasted more than 2,000 years, while the Mayan civilization built its city-states around 200 AD.
The bronze-made remains of tress unearthed at the ruins of the Shu Kingdom resemble the sacred ceiba tree, which symbolized the union of heaven, earth and the underworld in the Mayan civilization. “They are very important similarities,” says Santos, a Mexican archaeologist (考古学家) stressing that “the representations of tress in both cultures provide a symbolism that is very similar”.
The findings at the Sanxingdui ruins, considered one of the greatest archaeological discoveries of the 20th century, also show a new aspect of Bronze Age culture, indicating the ancient civilization already had technologies that were thought to have been developed much later.
While the lime span between the Shu kingdom and the Mayan culture is great, the findings highlight the closeness between the two civilizations. They developed in areas with comparable climates and reflected their worldview through related symbols. “In the end, man is still man, independent of time and space. What we have is that, at this latitude (纬度), both the Shu people and the Mayans looked at the same sky and had the same stars on the horizon,” the expert says.
One notable feature of the recent discoveries at Sanxingdui was the cross-subject work and technology applied by teams of Chinese archaeologists, which allowed the unearthing of artifacts as fragile as silk remains, which other types of less careful digging methods would not have been able to register.
Cooperation between Chinese and Mexican archaeologists could benefit projects in the Mayan world, where the rainy climate and humidity are problematic for the conservation of ruins.
“Every time our cultural knowledge increases, regardless of whether we speak one language or another, what it shows us is that we continue to be sister cultures and, therefore, the exchange of such knowledge is fundamental,” says Santos.

9 . In 1888 an Egyptian farmer digging in the sand near the village of Istabl Antar uncovered a mass grave. The bodies weren't human. They were feline-ancient cats that had been mummified(木乃伊化的)and buried in holes in astonishing numbers. "Not one or two here and there", reported English Illustrated Magazine, "but dozens, hundreds, hundreds of thousands, a layer of them, a layer thicker than most coal joints, ten to twenty cats deep." Some of the linen-wrapped cats still looked presentable, and a few even had golden faces. Village children peddled the best ones to tourists for change; the rest were disposed of as fertilizer. One ship transported about 180,000, weighing some 38, 000 pounds, to Liverpool to be spread on the fields of England.
Those were the days of generously funded explorations-that dragged through acres of desert in their quest for royal tombs, and for splendid gold and painted masks to decorate the estates and museums of Europe and America. The many thousands of mummified animals that turned up at religious sites throughout Egypt were just things to be cleared away to get at the good stuff. Few people studied them, and their importance was generally unrecognized.
In the century since then, archaeology has become less of a treasure hunt and more of a science. Archaeologists now realize that much of their sites' wealth lies in the majority of details about ordinary folks-what they did, what they thought, how they prayed. And animal mummies are a big part of that.
"They're really displays of daily life," says Egyptologist Salima Ikram. After peering beneath bandages with x-rays and cataloguing her findings, she created a gallery for the collection-a bridge between people today and those of long ago. "You look at these mummified animals, and suddenly you say, "Oh, King So-and-So had a pet". I have a pet. And instead of being at a distance of 5,000-plus years, the ancient Egyptians become clearer and closer to us."
