1 . The pyramids of Giza(吉萨金字塔) have been timeless(永恒的) symbols of Egyptian culture. But who actually built them? For years, we did not know for sure. But recently an ancient village was discovered near the pyramids. Close by, there was a cemetery(墓地) where pyramid builders were buried. From studying these places, archeologists are now certain that the pyramids were not built by slaves or foreigners (or aliens!). Instead, ordinary Egyptians built them.
It took about eighty years to build the pyramids. According to archeologists, about 20,000 to 30,000 people took part in the task. The workers had different roles. Some were responsible for digging up the rocks that were to be used. Others were tasked with moving them, while another group was given the job of shaping them into blocks. People also worked on different teams, each with its own name. These teams would often compete against each other to do a job faster.
Life for these workers was hard. “We can see that in their skeletons,” says Azza Mohamed Sarry El-Din, a scientist who has been studying the bodies that were found in the cemetery. The bones show signs of arthritis (关节炎), which probably developed as a result of having to carry heavy things for a long time. Archeologists have also found many female skeletons in the cemetery. The damage to their bones is similar to that of the men. Their lives may have been even tougher. Male workers would on average live to be between the ages of 40 and 45, but women would only live to be between the ages of 30 and 35. However, workers usually had enough food, and they also had good medical care when they got sick or hurt.
The work was hard, but the laborers were proud of their work. On a wall in Khufu’s Great Pyramid, for example, a group of workers wrote Friends of Khufu. “It’s because they were not just building the tomb of their king,” says Egyptian archeologist Zahi Hawass. “They were building Egypt. It was a national project, and everyone was a participant.”

5 . How far back does your family tree go? A hundred years? A thousand years? What about 6 to 7 million years?
An ancient skull (颅骨) found in Africa suggests that the human family might be that old. Discovered in 2001 in the desert of Chad, the skull was nicknamed Toumai by scientists. Toumai is a rare find. The skull is nearly complete and it even includes a few teeth. The Toumai skull is estimated to be between 6 and 7 million years old. Scientists are debating whether the skull is linked to humans.
The finding is not without controversy. Some scientists think that Toumai is the oldest known hominid (人科), or primitive human ancestor, ever found. Others say Toumai is an ape. Most hominids that scientists are aware of lived millions of years after Toumai. The most famous one is called Lucy. She lived in Ethiopia about 3.5 million years ago. While Lucy’s face looked like the face of a chimpanzee, Toumai’s skull has both human and ape-like features. Because Toumai’s skull looks different from other hominid skulls, some scientists think Toumai represents a whole new species.
Scientists were surprised to find a human-like face on a skull as old as Toumai’s. They thought hominids turned into humans step by step overtime. Scientists marked those changes on a timeline starting with a chimpanzee-like ancestor and ending with modern humans. Toumai’s human-like face and chimp-sized brain suggest that the development of hominids was not so simple. There may not be a direct line leading from Toumai to Lucy to us. Instead, the timeline might be like a tree with lots of branches. Different species in different places could have evolved human-like features at different times.
Scientists aren’t sure where exactly Toumai belongs on our family tree. Toumai could be like a great-great grandfather or just a distant cousin. Toumai could also be one of many types of hominids who wandered Earth millions of years ago.

6 . Human footprints in White Sands National Park in New Mexico aroused an argument two years ago when scientists found the prints to be surprisingly old.
In 2021, researchers described more than 60 footprints preserved in New Mexico. Radiocarbon dating(放射性碳定年法)of an aquatic(水生的)plant’s seeds in and around the footprints suggested that the first humans in North America came from Siberia via a land bridge between 23,000 and 21,000 years ago, almost 7000 years earlier than the long-held theory.
But some scientists noted that the aquatic plants used to date the footprints could have absorbed ancient carbon in groundwater. “There’s a possibility then for the plant to give overstated viewpoints on its age,” says Davis, who wrote a criticism of the 2021 paper.
Now, two other ways probably solving the argument, researchers report in the Oct. 6 Science. Pigati and colleagues radiocarbon-dated pollen(花粉)stuck in the same layers as some of the footprints. The pollen came from land plants, mainly pine, avoiding the groundwater carbon issue. The researchers also collected stones above the lowest footprints and used a dating method that estimates how long the stones had been buried.
The pollen gave an age range of 23,400 to 22,600 years old, and the stone an age minimum of about 21,500 years old. Both results proved the previous age estimate. Despite possible errors in the individual dating methods, “the data overall from the new study strongly indicate human presence in the Americas” around 22,000 years ago, says Bente Philippsen, a physicist at the Norwegian University.
One thing is certain: There’s still plenty to uncover about the footprints.Coauthor Kathleen Springer says, “We are learning more every time we go out there,” she says. “This paper is literally the latest chapter in the White Sands story.”

7 . The famous Sanxingdui (三星堆) Ruins site, dating back at least 4,600 years, is located in the city of Guanghan in Sichuan province, about 60 kilometers from Chengdu, the provincial capital. It is believed to be relics of the Shu Kingdom, which survived for over 2, 000 years.
The site was accidentally discovered by a farmer in the late1920s. From November 2019 to May 2020, Chinese archaeologists (考古学家) discovered six new sacrificial pits (祭祀坑) at the Sanxingdui Ruins, namely Pit No.3 to Pit No.8. After months of continuous digging at that time, more than 500 important treasures dating back to around 3,000 years were discovered. So far, archaeologists have discovered masses of important cultural items from six of the pits, including pieces of gold masks, gold foil, bronze masks, bronze trees and large numbers of ivories. The rest of the newly discovered pits are still being dug up.
“Surprisingly, we have found some never-heard-of-before bronze items,” said Lei Yu, from the Sichuan Archaeology Research Institute. “For instance, some large and well-made bronze items have strange-looking dragon or cow designs on them.”
In another major discovery, relics of silk products were found for the first time at Sanxingdui, which shows “the ancient Shu Kingdom was one of the important starts of silk in ancient China”, according to Tang Fei, head of the digging team.
The Sanxingdui Ruins site is regarded as one of the world's greatest archaeological findings of the 20th century, attracting millions of visitors from home and abroad now.

9 . For archaeologists (考古学家) in Israel, eight prehistoric ostrich (鸵鸟) eggs-thought to be between 4,000 and 7,500 years old-proved as valuable as treasure when they were dis-covered near an ancient fire pit in the Negev, a desert region in the south of the country.
They were discovered during an archaeological excavation (挖掘) in the agricultural fields of Be’er Milka, the Israel Antiquities Authority (IAA) announced on Thursday. The eggs’ location suggests that they were collected by the prehistoric (史前的) desert nomads (游牧民) who used the campsite, according to a press release from IAA, and further lab analysis will provide more information about their uses and ages. Although the nomads did not build permanent structures at this site, the finding allows us to feel their presence in the desert. The campsites were covered by sand, keeping the eggs exceptionally well-preserved.
Ostriches were common in the region until they became extinct in the wild during the 19th century. Their eggs were beautifully decorated and were prized items during the Bronze and Iron Ages (青铜和铁器时代). As well as being used as decorative items, ostrich eggs were also used as a source of food. One ostrich egg has the nutritional value of about 25 normal chicken eggs.
While ostrich eggs are not uncommon in excavations, the bones of the large bird are not found. This may indicate that in the ancient world, people avoided dealing with the ostrich and were content with collecting their eggs.

10 . In 1823, a young woman noticed a strange fossil (化石) on a beach near Lyme Regis, England. She dug out the bones and had them carried to her home.She carefully arranged the skeleton(骨架) on a table. Then she saw something extraordinary. The creature’s neck was a meter long-more than half the length of its body. It was unlike any animal living on Earth.
Even at a young age, Mary Anning had a talent for spotting unusual fossils. Her father died in 1810, leaving her family in.debt, so Mary began selling her fossils to collectors. At 12, she made her first major discovery—a crocodile-like skull(头骨) with a long skeleton. It turned out to be a sea creature that lived long ago. Named ichthyosaur, or “fish-lizard”, it was the first extinct animal known to science.
Fossil hunting brought in money, but it was a dangerous job. One day, a rock fall killed her dog and almost buried Mary. Despite the dangers, she continued to look for mew finds The long-necked fossil she unearthed in 1823 was another long-dead sea reptile(爬行动物). Known as a plesiosaur, it would inspire legends—including that of the Loch Ness Monster.
Mary was not only a skilled fossil hunter; she also carefully examined and recorded her finds. However, she wasn’t widely recognized in the scientific community. Only one of her scientific writings got published in her lifetime, in 1839. She was also not allowed to join London’s Geological Society, as membership was only available to men.
Mary Anning died in 1847, but her contributions have not been forgotten. Her finds are now displayed in museums in London and Paris. The beach near her home is a UNFSCO World Heritage Site, known as the Jurassic Coast. Her life continues to inspire visitors hoping to find their own fossil wonders. According to Britain’s Natural History Museum, Mary Anning was “the greatest fossil hunter the world has ever known”.
