2 . It may seem as if Mother’s Day was invented by a company named Hallmark, but people have been giving a shout-out to Mom for a long time. A more recent tradition was Mothering Sunday, which developed in the British Isles during the 16th century. On the fourth Sunday in April, young men and women who were living and working apart from their families were advised to return to their mothers’ houses.
Mother’s Day as it is observed in the United States started in the 1850s with Ann Jarvis, a West Virginia woman who held “Mothers’ Work Days” to promote health and hygiene at home and in the workplace. During the Civil War, Jarvis organized women to improve sanitary conditions for soldiers on both sides, and after the war she became a peacemaker, bringing together mothers of Union and Confederate soldiers and promoting a Mother’s Day holiday.
Jarvis’s work inspired another 19th-century woman, Julia Ward Howe. In 1870, Howe published her “Mother’s Day Proclamation”, which envisioned the day not as appreciation of mothers by their children but as an opportunity for women to exercise their collective power for peace. Howe started holding annual Mother’s Day celebrations in Boston, her hometown, but after about a decade the tradition faded away.
It was Jarvis’s daughter, Anna, who succeeded in getting Mother’s Day recognized as a national holiday. After her mother died in 1905, Anna started holding yearly ceremony on the anniversary. In 1912, West Virginia and a few other states adopted Mother’s Day. Two years later, Woodrow Wilson signed a resolution naming the second Sunday in May as Mother’s Day, making it an official US holiday.
It wasn’t long before whatever ideals the day was supposed to celebrate were buried under an amount of greeting cards and candy. By the 1920s, Anna Jarvis was campaigning against the holiday she had created. “I wanted it to be a day of emotionalism, not profit,” she said.

4 . While many of us might long to just sleep through this entire winter, humans, unlike a lot of other mammals - don’t have the capacity to hibernate (冬眠). But researchers think they have found some tell-tale marks on the fossils, which suggests that early humans may have survived the harsh winter by hibernating.
Bears have specialized metabolic (新陈代谢的) processes to protect them from this extended sleep, but sometimes this process doesn’t quite go to plan. For example, hibernators can end up with a host of diseases after hibernation if they don’t get enough food reserves before they go down for the winter. The researchers believe this may have been the circumstance of some human ancestors whose remains with deep cracks in bones were discovered in a Spanish cave called Sima de los Huesos. This deep hole is home to an incredible number of fossils, with archaeologists having discovered thousands of early humans’ skeletal remains that are around 430,000 years old and probably the ancestors of the Sima people or others.
In a paper published in L’Anthropologie, two experts argue that the fossils found in Sima de los Huesos show seasonal variations that suggest that bone growth got interrupted for several months of each year. They suggest these early humans found themselves being in metabolic states that helped them to survive for long periods of time in extremely cold conditions with limited stores of body fat.
The researchers admit the idea “may sound like science fiction”, but they point out that many mammals including primates (灵长类动物) do this. “This suggests that the genetic basis and physiology for such slow metabolism could be preserved in many mammalian species including humans," state Arsuaga and Bartsiokas.
However, Chris Stringer of the Natural History Museum in London pointed out that large mammals such as bears do not actually hibernate, because their large bodies cannot lower their core temperature enough. Instead, they enter a less deep sleep known as torpor. In such a condition, the energy demands of the human-sized brains of the Sima people would have remained very large, creating an additional survival problem for them during torpor.

10 . A Michigan farmer Bristle was digging with a backhoe (反铲挖土机) in one of his wheat fields when — bang — it struck a large bone.
Bristle contacted Fisher, a paleontology (古生物学家) professor at the University of Michigan. Fisher rushed to the farm and identified the bone as a fossil of an Ice Age mammoth (猛犸象). Since it was harvest season, Bristle gave Fisher and his students only one day to remove the rest of the fossils from the ground. The team found 20 percent of the animal’s bones, including its skull, tusks, pelvis, and shoulder blades as well as some teeth, ribs, and other bones.
The age of a mammoth can be determined by counting the rings in one of its tusks. Like the rings in a tree trunk, each ring stands for one year of a mammoth’s life. Fisher thinks that the bones are supposed to belong to male mammoth around forty years old. It was probably a rare hybrid of a woolly mammoth and a Colombian mammoth that lived between 11,700 and 15,000 years ago during the Pleistocene lee Age, when ice sheets covered much of Earth’s land.
The bones appeared to have been cut up and some of them were missing, leading Fisher to conclude that early humans must have killed the animal and stored its meat so they could return to it at a later time. Some other indications of human activity include a stone flake (薄片) that might have been from a cutting tool and the arrangement of the neck bones in order. If the mammoth had died naturally, its bones would have scattered randomly.
In the US, fossils found on private property belong to the owner of the land. However, Bristle donated the fossils to the University of Michigan for further study. Fisher hopes to display the bones at the University of Michigan Museum of Natural History, possibly combined with fiberglass models of bones from other Michigan mammoths to form a complete Mammoth skeleton (骨架).
