Marmoset monkeys exist on a branch of the evolutionary tree that is distinct from the one that led to humans. But they constantly _______ researchers with social behavior that seems pretty highly evolved. Their social organization and _______ practices could have been the model for the phrase “It takes a village.” A dominant male and female breed, and their babies are carefully looked after by _______ family members who then aren’t free to breed themselves.

A new study further _______ the marmoset’s reputation for admirable community values. Researchers report that these caregivers share their food more generously with little ones _______ than when they’re surrounded by the watchful eyes of other community members. In complex societies where individuals band together for mutual protection, researchers have come up with a few widely accepted explanations for _______ behavior. But specific acts, like sharing a delicious cricket (蟋蟀) with a begging baby marmoset, seem to need more specific explanation.

One possibility is that an individual practices _______ as a means of enhancing his status among peers. By presenting that he is so well gifted with material goods that he can give some away, this do-gooder enhances his power within the group. That, in turn, may _______ prospective mates.

The other explanation for charitable behavior _______ that kindnesses extended to others are simply the fees of group membership, which offers some future promise of a chance to mate.__________ to share would result in exclusion from the group and a loss of potential partners.   

Scientists call this the “pay to stay” model. Importantly, for both of these models to work, acts of kindness must have a(n) __________. That suggests you would see more sharing in group settings; away from judging eyes, a caregiver might be more likely to keep food for himself or herself. And yet, in 2,581 tests conducted with 31 adult and 14 baby marmosets, the __________ appeared to be true.

Anthropologists (人类学家) from the University of Zurich carefully documented how often, in groups and in conditions that found caregiver and baby separated from the crowd, an adult would share his or her cricket. When alone with a baby __________ for a taste, adult marmosets shared their cricket 85% of the time. When in a group, caregivers offered up their cricket 67% of the time.” Our results show that helping in common marmosets is not driven by__________management or punishment avoidance, “the study authors reported. Rather, it is driven by a deep-down ____________ to help that is more strongly expressed when individuals are alone with young.”

Animal Rights

Every conscious being has interests that should be respected. No being who is conscious of being alive should be devalued to thinghood, dominated, and used as a resource or _________. The key point of the idea known as animal rights is a movement to extend moral consideration to all _________ beings. Nobody should have to demonstrate a specific level of intelligence or be judged beautiful to be given moral consideration. No being should have to be useful to humanity or capable of accepting “duties” in order to be extended moral consideration. _________, what other animals need from us is being free from duties to us.

Animal rights is about letting animals live on their own terms. It can be written into our laws, but is not an actual list or bill of rights as we have for human society. It begins with our promises not to act like _________ of others. Animal rights is about justice — treating animals fairly.

Why is animal rights _________? It is because we humans often act as though we are the only beings on the planet. Although we depend on other animals for our very survival, humans are the only animals that have upset the balance of nature. There are lots of ways that humans _________ animals. We domesticate them and use them for food, even though our nutritional needs can be completely supplied by a(n) _________ diet. Although other materials are available, we use animal’s skin and other body parts for clothing, furs, hats, boots, jewellery and even pet toys. Humans can talk about it but animals cannot. All animals wish to experience life in its fullness. Unlike many animals who have to kill to survive, humans do not. Why should humans cause _________ to other beings when it’s not necessary?

As we do, animals protect their children; they feel fear; they warn each other of dangers; they play. We might differ from other animals in some ways, but that doesn’t give us the right to _________ them down, take their lands, pollute their waters, or use them for our conveniences. Animals also experience pain and it’s not difficult to observe ____________ of pain in the way a conscious being reacts to it. We take advantage, cause distress, and act ____________ when we use animals for amusement. Lots of pets are ____________ on the streets when their owners no longer find it convenient or affordable to keep or care for them.

Whether we admit it or not, it’s a prejudice to think we are ____________ to animals and that it is our right to control them, which can only make people act mean, hateful or neglectful. However, each of us has within us the power to ____________. We can adopt a different attitude, one that reshape our destiny. This will have wonderful effects on the planet’s other communities, for life is ____________ avoiding suffering. It is interacting, singing, pursuing joy. We humans can learn to live responsibly, with respect, kindness and love.

One morning in early fall, I spotted a pair of wild geese on our pond. The beautiful sight caught me by ________, because we had never seen geese there before.

Dogs Bow to Wolves as Cooperators

If you need help herding some sheep or retrieving a stick, you can count on your canine companion, because dogs always seem to be keen on _________. But only if their partner is a person. When it comes to cooperating with one another, dogs are truly _________… and instead it’s wolves who’ve mastered the art of teamwork. That’s according to a study in the Proceedings of the National Academy of Sciences.

For thousands of years, humans have been breeding dogs that can do all sorts of neat tricks. And because pups aim to please, we’ve come to think that domestication has somehow _________ dogs’ powers of cooperation. But researchers in Austria have been wondering whether that notion could be barking up the wrong tree. Because left to their own devices, dogs are bigger _________ than wolves.

“So wolves live in _________ family packs, they cooperate in raising the young, they also cooperate in hunting and in defending their territory. So they really have a strong _________ on cooperation in many aspects of their lives. _________, free ranging dogs actually seek food mostly by themselves. It’s only mothers that raise their young. And they do form packs but they tend to be somewhat more _________, if you want.”

That’s Sarah Marshall-Pescini of the Wolf Science Center at the University of Vienna. She and her colleagues decided to test dogs’ and wolves’_________ powers of cooperation. In the setup, a pair of animals… either two dogs or two wolves… is __________ with a contraption (装置) that will allow the participants to __________ a tray of food… but only if both members of the team simultaneously pull on the two ends of a rope.

A dozen wolves and 14 dogs took the challenge. And the results? The wolves ran circles around their doggie descendants. In some 400 attempts, the wolf teams __________ a snack 100 times, which may not sound all that impressive until you compare it with the doggie couples, who, in nearly 500 trials, succeeded only twice.

Now, it’s not that dogs are less earnest learners. Or that they turned tail and avoided the apparatus (装置). Marshall-Pescini says the pooches (杂种狗) were __________ about the device.

“What seemed to be happening was that they didn’t want to get into conflict with each other. So they wouldn’t both go and try things on it but rather took it __________. And this really set back their capacity to cooperate.”

So rather than step on each other’s toes, the dogs took turns bowing out, giving their teammate a chance at the plate. That show of social grace left the poor pups with their tummies growling. And no __________ to enjoy.
