6 . In the late 1970s, archaeologists (考古学家) uncovered the remains of a woman and a young dog, her hand resting on the puppy’s chest in a 12,000-year-old village.
The find is some of the earliest evidence of the bond between humans and dogs. But even after years of study researchers are divided on how this bond began. Did it arise over thousands of years, as early dogs became tamer (驯服的) and more accustomed to human behaviors? Or was this fire already burning in the ancestors of dogs: the gray wolf?
Christina Hansen Wheat, a behavioral ecologist at Stockholm University, and workmates hand-raised 10 gray wolves from the time they were 10 days old. When the animals were 23 weeks old, a caregiver led them one at a time into a mostly empty room. Over the course of several minutes, the caregiver exited and entered the room, sometimes leaving the wolf alone, sometimes leaving it with a complete stranger. The team repeated the experiment with 12 23-week-old Alaskan huskies (哈士奇), which they’d raised similarly since puppyhood.
For the most part, the scientists saw few differences between the wolves and the dogs. When their caregiver entered the room, both species scored 4.6 on a five-point scale of “greeting behavior”—a desire to be around the human. When the stranger entered, dog greeting behavior dropped to 4.2 and wolf to 3.5, on average, suggesting both animals made a distinction between the person they knew and the one they didn’t. It’s this distinction that the team counts as a sign of attachment.
In addition, dogs barely paced—a sign of stress—during the test, while wolves paced at least part of the time. However, the wolves stopped pacing almost entirely when a stranger left the room and their caretaker returned. Hansen Wheat says that’s never been seen before in wolves. It could be a sign, she says, that the animals view the humans who raised them as a “social buffer”.
For her, that’s the most interesting part of the study. “If this is true, this sort of attachment is not what separates dogs from wolves,” she says. In other words, it didn’t have to be bred into them by humans, but could have been the seed we selected for, and then strengthened over thousands of years.

7 . Kiwis are unique in a lot of interesting ways. They have many characteristics that are not found in any other bird.
It is assumed that the kiwi’s ancestor was able to fly and reached New Zealand. Once on the island, it lost its ability to fly and eventually became the kiwi known today. Kiwis have feathers that look like hair and very strong and muscular legs. They rule the ground instead of the air. They can smell very well. Kiwis are quite shy and usually only come out at night. Kiwis can live a long time, between 25 and 50 years.
A female kiwi carries a huge egg about its body size. The kiwi is about the same size as a chicken but its egg is actually six times as large as a chicken’s egg. The reason for this is that the kiwi doesn’t have to fly, so there aren’t any limits on its weight. The female has to eat three times as much as usual to help the egg develop. Right before the egg is laid she can’t eat anything because the egg presses against her stomach, leaving no room for food.
All kiwi species are endangered. On average, twenty-seven die each week. They have been affected most by deforestation and invasive mammals. Before humans came to New Zealand, the only mammals on the island were bats and seals. The kiwi never had to worry about predators before, but now since it cannot fly, and lays its eggs on the ground, it is pretty defenceless against invasive mammals such as rats and stoats. Stoats kill a lot of the chicks, while dogs kill a lot of adult birds, usually by accident, because they are quite delicate (脆弱的) .

8 . A new study has found that all dogs have different personalities—even dogs of the same breed(品种).
Elinor Karlsson studies genetics at the University of Massachusetts. She co-wrote a report about the study, which appeared recently in the publication Science.
Karlsson said, “Every dog really is an individual,” noting that there is “a huge amount of difference” even between dogs that look the same.
At a New York dog park, dog owners talked about the different characteristics of their pets. Elizabeth Kelly owns an English springer spaniel. She called her dog friendly, but also “kind of the queen bee.” In other words, her dog likes to act like it is in charge of other dogs. Suly described her yellow Labrador as “calm, lazy and shy.”
The idea of dog breeds is quite recent. Around 160 years ago, humans began to breed dogs to have certain physical qualities, such as fur, color and ear shape.
Karlsson said her aim was to learn how much a dog’s breed affects their behavior. The answer? Breed does not decide an individual dog’s personality.
Karlsson’s team gathered information from 18,000 dog owners and studied the genetic code of over 2,000 dogs. The researchers found that some qualities are based on genetics. However, it is not sure that two dogs of the same breed will behave in the same way.
For example, huskies and beagles, may be more likely to howl—or make a long, loud barking sound. But many of these dogs do not howl, as owner observations showed.

10 . The climate change may lead humans to shrink in size. Steve Brusatte, a researcher at the University of Edinburgh, believed that the way that other mammals have previously responded to periods of climate change could offer an insight into humans’ future. He compared the possible difficult situation of people to that of early horses. Those horses became smaller in body size as temperatures rose around 55 million years ago.
In his book, Brusatte mentions that animals in warmer parts of the world today are often smaller than those in colder areas. “Becoming smaller was a common way that mammals deal with climate change.” Brusatte told The Guardian, “That’s not to say every species of mammal would get smaller, but it seems to be a common survival trick of mammals when temperatures rise very quickly.”
In a recent study, researchers studying human remains over the past million years have also suggested that temperature is a main predictor of body size change, while scientists studying red deer have said that warmer winters in northern Europe and Scandinavia may lead to the body size of these animals becoming smaller.
However, not all experts agree that rising temperature causes mammals to shrink. Adrian Lister, an expert from the Natural History Museum in London, said, “The relationship shown by the recent human remains study is weak. I prefer to believe that the strong connections between temperature and mammal body size may often depend on the availability of food and resources.”
Lister has also expressed doubts about the idea that humans will shrink as the climate heats. “We are not really controlled by natural selection,” he said. “We wear clothes. We have got heating. We have got air conditioning if it is too hot.”
