Hey there! Welcome to Life Noggin! Any dog lover will tell you that our furry friends make our lives better.
大家好！欢迎来到打脑洞开的生命奇想！任何爱狗人士都会告诉你，我们毛茸茸的朋友使我们的生活更好。
they save lives as police and search and rescue dogs and take care of us as therapy and service dogs.
它们作为警犬和搜救犬拯救生命，作为治疗及服务犬照顾我们。
Studies even show that they improve our health by reducing stress and lowering blood pressure and cholesterol.
研究甚至表明，它们可以通过减少压力、降低血压和血脂改善我们的健康。
They also make Twitter slightly more tolerable thanks to their adorable little faces,
多亏了它们可爱的小脸，它们让推特更容易让人接受。
That's why whenever I get stressed out, I spend time with my buddy - professor Cuddlesworth.
这就是为什么在我压力山大的时候，我会和我的盆友抱抱教授一块玩耍。
Here boy! That's a good dog! Yes you are! It's clear that life without them would be horrible for us, but what about them?
嘿小子，这是条好狗！是的你是！很明显，没有它们，我们的生活会很糟糕，但是对他们来说呢？
If every human suddenly disappeared, what would happen to our dogs? Do they even need us?
如果所有人突然消失了，我们的狗会怎么样？它们需要我们吗？
Researchers estimate that we've been domesticating dogs for ten to forty thousand years.
研究人员估计，我们驯化狗狗的时间已经有一到四万年了。
Since then, we have provided them with food, protection, and shelter.
从那时起，我们为它们提供食物，保护和住所。
Without humans, dogs that are used to being cared for would need to quickly learn how to fend for themselves.
没有人类，习惯被照顾的狗狗就需要快速学会如何养活自己了。
Since no one will be filling up their food bowl, they will need to scavenge or hunt for food.
因为没有人会喂它们食物，它们需要捡拾食物或者猎取食物。
So, dog breeds that are known for their tracking and hunting abilities, like spaniels and retrievers, would have it much easier than other breeds.
所以像猎犬和寻回犬这样的以跟踪和狩猎著称的犬类就会过得比其它犬类更轻松。
They will also be living in a world without temperature control.
它们也会生活在一个没有温度控制的地方。
So some dog breeds that struggle in the heat or cold wouldn't fare well in those climates.
所以一些难以在炎热或寒冷中生存的狗在那些气候条件下不能很好地生存。
Dogs with thick coats, like the husky, or brachycephalic dogs with flat faces, like the bulldog, could easily overheat in hot regions.
像哈士奇那样的厚毛狗，或者像牛头犬那样的扁脸短头狗，在炎热的地区很容易过热。
While breeds with short hair, like the boxer, or dogs with low body fat, like the greyhound, would freeze in cold climates.
而像拳狮犬那样的短毛犬，或者像灰狗这样身体脂肪含量低的狗，在寒冷的天气中会被冻死。
Good thing professor Cuddlesworth here falls right in the middle. Plus, he's a skilled hunter. Yes you are!
好消息是抱抱教授就处在中间。而且，它还是个娴熟的猎手。是的你是！
Since dogs were bred to be less aggressive than their wolf ancestor,
因为被喂养的狗的攻击性不如它们的狼类祖先，
the portion of their brain responsible for the fight or flight response has shrunk,
负责它们战斗或逃跑反应的大脑区域已经减少了，
which will make it difficult for most dog breeds when faced with predators.
这会使大部分犬类在面对捕食者时变得很困难。
Over time, it's likely that most dogs would adjust to their new lives
久而久之，一旦多数狗发展了像寻找食物和住所、构建同盟这样的生存技巧时，
once they developed survival skills like finding food and shelter and forming alliances.
他们就会适应它们的新生活。
But it may take a few generations. We've seen this happen with dogs who escape or are released into the wild. Without human contact, they become feral.
但是这可能需要几代狗的时间。我们已经看到，那些逃跑或被放归野外的狗会出现这种情况。没有人类接触，他们就变得凶猛。
In a 1995 study, the first few generations of feral dogs had high rates of juvenile mortality and indirectly depend on humans for food.
在一项1995年的研究中，最初的几代野生犬有较高的幼体死亡率，在获取食物方面严重依赖人类。
However, after long periods of time when natural selection has taken it course -
然而，在自然选择发生的很长时间里，
we're talking thousands of years here - wild dog species emerge.
我们谈论的是数千年的时间，野狗物种出现了。
This is thought to be the story of the Australian dingo. So, eventually, dogs will be okay.
人们认为这就是澳洲猎狗的故事。所以，最后，狗会没事的。
Though it is reassuring that your little buddy needs you just as much as you need them.
让人安心的是，你的小朋友需要你们就像你们需要它一样。
So do you have dogs? What kind, and let me know their name in the comment section below, or tell us what we should talk about next!
你有狗吗？什么品种呢？请在评论区告诉我它们的名字，或者告诉我们接下来要谈论什么？
