2 . Imagine this: You’re digging a well, and instead of hitting water, you unearth a headless human body made of pottery. This actually happened to farmers in Shanxi province in central China in 1974. Local archaeologists heard of the find and biked over to investigate. They realized that the figure had come from a tomb built over 2,000 years ago for China’s first emperor, Qin Shihuang. Archaeologists finally discovered three separate pits (穴) filled with 8,000 life-sized statues, all made from terracotta — a type of fired clay.
About a mile away from these pits, there’s a large mound (山丘). Archaeologists know that this is the main part of Qin Shihuang’s tomb, but they have never looked inside. They have left it alone out of respect for the first emperor and to protect the tomb as it is.
“Many people wish to see the treasures and mysteries inside, but we cannot,” says Xiuzhen Li, an archaeologist. Opening the tomb could damage its contents. Someday, Li hopes, we’ll have technology that will let us see inside the main part of the tomb without opening and disturbing it.
“Probably in the near future we’ll have some new technology that can see inside like an x-ray,” she says. Scientists are working on techniques that make it possible to see underground. Another idea is that a tiny robot could enter through a small hole and capture videos of what it sees. Even if this robotic exploration is done very carefully, however, it would still damage the tomb. For now, the Chinese government prefers to wait to do anything until they have even better technology.

3 . A small group of paleontologists (古生物学家) recently discovered 10 species of ancient mammals previously unknown to science with the help of an enormous number of helpers at their dig site: ants.
The study of ancient mammals throws new light on the diversity of mammals that existed in North America around 33 million to 35 million years ago, when the climate was changing dramatically. It also pays attention to the harvester ants, with which researchers have long had a love-hate relationship. “The ants are not fantastic when they’re biting you,” said Samantha Hopkins, a professor of Earth Sciences at the University of Oregon. “But I’ve got to appreciate them because they make my job a whole lot easier.”
Most species of harvester ants live in subterranean caves that sit beneath a small hill of dirt. They strengthen the dirt by covering it with bits of rock and other tough materials. The ants have been known to travel over a hundred feet from their caves and to dig six feet deep in pursuit of materials that help secure their caves. The materials include fossils. Harvester ants can carry materials 10 times to 50 times the weight of their body, although they do not weigh very much, so the heaviest fossil they can collect weighs less than the average pill.
Given the size, harvester ant hills are hot spots for what scientists call microvertebrate (微型脊椎动物) fossils, which are animal fossils too small to see without a microscope. For over a century, scientists like Dr. Hopkins have found sediment (沉积物) off the sides of harvester ant hills in search of these fossils, making it easier to find large numbers of fossilized mammal teeth without spending hours in the field sifting through (仔细检查) sand and dirt.

4 . Humans evolved from apes. This is what we learned in biology class. But what came before apes? Chinese scientists have discovered fossils that could enrich the evolutionary story of how humans evolved from fish.
According to four articles published in the journal Nature in late September, Chinese researchers found fish fossils that provide the “missing link” about the origin of the jaw, a key feature that 99.8 percent of vertebrate (脊椎动物) species have.
Zhu Min, a lead researcher of the studies from the Chinese Academy of Sciences, said that the findings drew a large amount of interest in the science world due to the importance of jaws in animal evolution.
However, the rise of the jaw had been a mystery due to a lack of sufficient fossil evidence to support that jawed vertebrates lived 450 million years ago.
The latest findings made by Zhu’s team presented a set of five surprisingly well-preserved fish fossils that included three whole-bodied fish, helping scientists paint a more accurate evolutionary picture of the origin of the jaw. The fish fossils were discovered at two sites in Chongqing and Guizhou, whose strata (岩层) date back to the Silurian Period that began around 440 million years ago.
These fossils show that jawed fish were already thriving (繁荣) in the world’s ancient oceans at that time. Later on, more diverse and larger jawed fish evolved and began to spread around the world, paving the way for some fish to eventually go on land and evolve into other animals — including humans.
“These fossils provide an unprecedented (前所未有的) opportunity to peek into the ‘dawn of fish’ and help scientists trace many human body structures back to these ancient fish thus filling some key gaps in the evolutionary history of how fish evolved into humans,” Zhu said.

5 . Fossils are well preserved remains, impressions, or traces (痕迹) of animals and plants that lived long ago. Paleontologists (古生物学家) divide fossils into two main groups. Some fossils, called body fossils, show the structure of the plant or the animal. They form directly from the remains of plants and animals. Other fossils, called trace fossils. They record signs of animal or plant activities, such as walking, feeding, scratching, or even resting.
Most animals and plants don’t become fossils after they die. They break down into little bits or may be eaten by other animals. But some remains get buried too fast, avoiding those things happening. An animal might die near a body of water and sink to the bottom, where its remains get covered in sediment (沉积物). As sediment builds up, mineral-rich water seeps into the remains, leaving minerals in the tiny spaces of the bones and even replacing the original bones. The new minerals react with those in the animal’s remains and then harden into fossils.
Most fossils are buried deep in the Earth. As the Earth’s surface changes, scientists can dig up new fossils and learn more about past life and the Earth’s history. In rock that formed before a certain time, roughly 2.8 million years ago, scientists will not find human fossils.
Fossils are our keys to understanding prehistoric life and the Earth’s history. By studying fossils, we learn about a great variety of plants and animals that lived in the past. We can know what they looked like, how and where they moved and what they ate. By comparing fossils from different time periods, we can track the evolution of a species, see how it adapted to changes in its environment, and understand more about the climate and environment where the fossils were buried.

Clues at Ancient Lake Site Reveal Earliest Known Cooked Meal
Scientists have found the earliest known evidence of cooking at an archaeological site in Israel. The discovery has suggested prehistoric humans were able to deliberately make fires to cook food at least 780,000 years ago.

7 . A rich burial was unearthed by archaeologists at La Almoloya, southeastern Spain that is the cradle of the El Argar civilization, which lived in the region during the Bronze Age.
La Almoloya was a primary center of politics and wealth in the El Argar territory, and although the discovery was made in 2014, experts are now taking a closer look at the sociological and political context of the unearthed treasure.
The remains of a woman, along with a man who may have been her husband, were discovered in the forested hills of the area. Radiocarbon dating suggests the burial happened around 1700 BC. The pair were found with 30 objects containing precious metals and semi-precious stones, including the silver diadem (王冠), which encircled the skull (颅骨) of the woman.
Experts believe that the man in the grave was probably a warrior; wear and tear on his bones indicate he spent a lot of time on horseback, and his skull had deep scars from a facial injury, while gold plugs through his earlobes indicated he was someone of distinction.
The woman, named the “Princess of La Almoloya”, was buried a short time after the man, with vast quantities of jewellery: bracelets, earlobe plugs and rings, to name a few. The grave goods of the woman were worth tens of thousands of dollars in today’s money.
“We have two ways of interpreting this,” says archaeologist Roberto Risch of the Autonomous University of Barcelona. “Either you say, it’s just the wife of the king; or you say, no, she’s a political personality by herself.”
Risch is a co-author of a study that was recently published about the important findings, that noted the building under which the grave was found was of equal importance—a building specifically dedicated to governing purposes in Western Europe. A wide hall was excavated (挖掘), with high ceilings, a raised platform, and a capacity for more than 50 people to sit on benches that lined the walls. “It’s a building where people could be sitting listening to each other, or to someone explaining something,” says Risch, “There is no evidence of food and no clear-cut religious artefacts, so it doesn’t look like a home or a temple.”
The discovery at La Almoloya shed new light on the politics and gender relations in one of the first urban societies of the West. Previous findings have revealed that women were considered adults at a much younger age than boys were. Excavated grave goods have highlighted that girls as young as six were buried with knives and tools, but boys would be in their teens by the time they would be buried alongside such objects.
Additionally, the graves of some women from EI Argar were reopened generations later to bury other men and women, an unusual practice that experts believe would have been a very high honor. “What exactly their political power was, we don’t know,” Risch adds. “But this burial at La Almoloya questions the role of women in [Bronze Age] politics... it questions a lot of conventional wisdom.”

9 . Some late Stone Age Europeans may have carried make-up inside mini bottles worm around their necks or waists more than 6,000 years ago.
Researchers have found traces of ingredients known to be used in cosmetic formulations (配力) by later civilizations inside small bottles unearthed in Slovenia, dating to between 4350 and 4100 B.C, more than 200 years earlier than previously thought. In 2014, Bine Kramberger at the Institute for the PCHS found a mini ceramic bottle al an ancient site once occupied by people of the Lasinja culture in around 4350 B. C. More than 100 similar bottles have also been found.
Their purpose was unknown, but it is thought that some might have been children’s toys. Curiously, most of them have holes in their tiny handles or edges that archaeologists think people threaded string through, enabling them to be worn around the neck or waist. But Kramberger’s find was different because it contained a solid white substance. “It was clear that it had valuable information because in such old archaeological sites, we rarely find containers that still keep remains of their former content,“ he says.
Long and thin stone tools were found near the bottle, which could have been used to extract the substance within. Now, Kramberger and his colleagues have analysed the substance in the bottle and examined 13 others from the same period.
The mystery material contained a white lead mineral called cerussite, while different lead minerals were identified in two other bottles. The three lead-containing bottles also had contents coming from beeswax (蜂蜡) inside.
The bottles’ contents could have been used for painting. says Kramberger. But he says it is more likely that they were cosmetics, because they contained common ingredients for such products known from later cultures. Cerussite powder was very popular among the ancient Greeks and Romans for skin whitening and remedies, despite is known toxicity (毒性).
Gaydarska says the new study supports what archaeologists have long thought—“that the abilities and cultures of Neolithic people were far more comprehensive and complicated than they are often given credit for”.
