如果所有的动物都像人类一样聪明，那么哪个物种会主宰世界呢?

Lyapunova
This is a horror scenario.
It would be a brutal blood bath for a period while determining dominance. But humans would almost certainly come out on top, because humans have a lot of advantages besides just intelligence that people fail to realize, forget about or discount. Humans are a Great Ape and the greatest threats would come from the other Great Apes. But humans have significantly better fine dexterity, are better able to make and wield tools, are more adaptable to very different environments, have better endurance and capacity for travelling long distances, etc.

这是一个可怕的场景。
在一段时间内，这将是一场残酷的血战来决定统治地位。但人类几乎肯定会胜出，因为除了智力之外，人类还有很多优势，只是人们没有意识到、忘记或低估了这些优势。人类是类人猿，最大的威胁来自其他类人猿。但人类有明显更优越的灵巧性，更擅长制造和使用工具，更能适应非常不同的环境，有更好的耐力和长途旅行的能力，等等。

Yes, especially gorillas, have some advantages too. They are slightly stronger and tougher and have natural stronger finger nails and fangs as weapons. But, they cannot throw spears as well as humans can, they wield swords as well as humans can, they cannot wield bows and arrows as well as humans can, and with armor humans can become quite tough.
Virtually naked humans have taken down lions, elephants, bison, gorillas, rhinos, etc. by using weapons and pack tactics. Let humans put on some heavy armor while wielding medi weaponry and they are a lot scarier. Give them modern weaponry and they are scarier yet. Gorillas could not handle heavy armor, because it would rapidly overheat them. Humans are good at shedding their heat, way better than gorillas.

是的，尤其是大猩猩，也有一些优势。它们更强壮，有天然更强大的指甲和獠牙作为武器。但是，他们不能像人类那样投掷长矛，他们不能像人类那样挥舞剑，他们不能像人类那样用弓箭，而且有了盔甲，人类也可以变得非常强壮。
几乎全裸的人类已经通过使用武器和狼群战术撂倒了狮子、大象、野牛、大猩猩、犀牛等。让人类在使用中世纪武器时穿上厚重的盔甲，他们会更可怕。给他们现代化的武器，他们就尤为可怕了。大猩猩无法驾驭厚重的盔甲，因为盔甲会迅速使它们过热。人类善于散热，比大猩猩好得多。

So, what would likely happen is a fight to extinction between the top competitors for dominance, resulting in all other Great Apes being killed off. Then, similar fights to extinction would be taking place between all kinds of different species as they fought for their local dominance. Then humanity would enslave all the survivors and maybe, far enough into the future, we would eventually mature enough to make all survivors equals in society.
(Edit: As I have thought about this more from responding to comments, it should be noted that Humans would get into wars with each other, as would members of the same species of other animals fighting among themselves. But, while I can see Humans enslaving Human level intelligent animals in this, they might also very likely make treaties with rights for animals, make alliances, and would likely become Vegan as part of the bargaining.)

因此，很可能发生的是顶级竞争对手之间争夺统治地位的灭绝大战，导致所有其他类人猿灭绝。然后，各种不同的物种之间也会为各自的统治地位发生类似的灭绝斗争。然后人类会奴役所有的幸存者，也许，到遥远的未来，我们最终会足够成熟，让所有幸存者在社会上平等。
编辑:我从回复评论中思考了更多这个问题，应该指出的是，人类会陷入彼此之间的战争，就像同一物种的其他动物之间的战斗一样。但是，虽然我可以看到人类在奴役人类水平的动物，但他们也很可能与动物签订权利条约，缔结联盟，并可能成为素食主义者来作为谈判的一部分。

BUT!!!
If we go a century or two into the future, this will turn into a good scenario. This is because we are inside the technological singularity and within 50 to 200 years we will begin evolving into a race of pure minds who will use custom-designed cybernetic bodies like we do clothing and accessories. Once we have this technology, all self-aware animals can be rapidly evolved into becoming full equal members of that civilization of pure minds and they will be able to wear whatever body they want, well, that does not already belong to someone else.

但是！如果我们展望未来一两个世纪，这将会变成一个很好的场景。这是因为我们处于技术奇点之中，在50到200年之内，我们将开始进化成一个纯思想的种族，他们将使用定制设计的、可自由操控的身体，就像我们制作服装和配饰一样。一旦我们有了这项技术，所有具有自我意识的动物都可以迅速进化成完全平等的成员，成为那种纯净心灵的、文明的成员，他们将能够穿戴任何他们想要的身体，届时就不再是外人了。

Robb Young
I’m not sure about the horror show, although there certainly would be a period of adjustment.
Surely if every animal was given the intelligence of humans, we’d suddenly be negotiating with them rather than killing them and eating them or going to war with them? (“Why am I locked in a zoo, I have things to do”)
The first thing that might happen is a lot of people would starve as we tried to adjust to a plant based diet as a vast number of people would have an issue eating sentient creatures (far more than they do now). Meat would actually be murder in this case. Farming practices would change, diets would change, land use would change.
There would always be a few that wanted to do nothing but fight, as there are humans. But the food chain would be a bigger issue not just for us, but for all those wild animals that suddenly felt empathy for their prey.

虽然肯定会有一段调整期，但我不确定恐怖场景是怎样的。
当然，如果每一种动物都被赋予了人类的智慧，我们就会突然与它们谈判，而不是杀死它们，吃掉它们，或与它们开战?(“为什么我被关在动物园里，我还有事情要做”)
第一件可能发生的事情是，当我们试图适应以植物为基础的饮食时，许多人会饿死，因为大量的人会对吃有知觉的生物遭遇障碍(比当前多得多)。在这种情况下，吃肉实际上就是谋杀。耕作方式会改变，饮食会改变，土地使用也会改变。
总有一些人除了战斗什么也不想做，就像人类一样。但食物链不仅对我们来说是一个更大的问题，对所有突然对猎物产生同理心的野生动物来说也是如此。

Richard Chiu
Ants.Specifically, fire ants.
That’s not specific enough because there are a couple hundred different species of them, but they’ll gang up on humans (as the biggest existential threat to the entire biosphere) before settling things amongst themselves.
Humans may have a large starting advantage through current control of most technology, but to ensure continued dominance against ants (and other small things, like spiders) the only option is total destruction of Earth’s biosphere.
There are a lot of species that would probably be willing to coexist with humans if they had human intelligence, but ants (and a lot of other bugs) would make extermination of humans a primary obxtive out of rational concern for their own safety.

蚂蚁。具体来说，火蚁。
这还不够具体，因为它们有几百种不同的物种，但它们在解决彼此之间的问题之前，会联合起来对付人类(作为整个生物圈最大的生存威胁)。
通过目前对大多数技术的控制，人类可能有一个巨大的开场优势，但要确保对蚂蚁(以及其他小东西，如蜘蛛)的持续统治地位，唯一的选择是彻底摧毁地球的生物圈。
有很多物种可能愿意与人类共存，如果它们有人类的智慧的话。但蚂蚁(和许多其他虫子)出于对自身安全的理性考虑，会把消灭人类作为首要目标。

Ants with human intelligence, but ant social organization, could readily sabotage nearly all electronic technology in a matter of hours of deciding to do so. This wouldn’t need to be a centralized decision at first, ants dealing with individual humans as local problems would independently make the decision to take action billions of times. The great majority of humanity would lose access to all modern technology without the need for any global coordination.
After that, the remaining humans will be desperately trying to kill all insects (and most other animals) and the logical response is extermination of all humans, then all mammals, and probably nearly all chordates. The big advantage of chordates that pays for their metabolic expenses is that they are smarter than other animals, but if all animals have human intelligence without needing to be humans or even chordates, then chordates lose.

具有人类智慧的蚂蚁，加上蚂蚁的社会组织，可以很容易地破坏几乎所有的电子技术，只需要几个小时。这在一开始不需要是一个集中的决定，蚂蚁会把单个人类作为局部问题来处理，数十亿次地独立做出采取行动的决定。
绝大多数人类将失去使用所有现代技术的机会。
在那之后，剩下的人类将拼命地杀死所有的昆虫(和大多数其他动物)，而合乎逻辑的反应是灭绝所有的人类，然后是所有的哺乳动物，可能还有几乎所有的脊椎动物。脊椎动物的最大优势是它们比其他动物更聪明，但如果所有动物都具有人类的智力，而不需要成为人类或脊椎动物，那么脊椎动物就失去了自身最大的优势。

Duncan Oliver
Actually, it would probably still be humans.
First of all, tool use is, to borrow a term, game-breaking. Animals without body shapes that allow them to make and use tools effectively will not be able to dominate the planet the way humans do. As smart as dolphins are, for example, they aren’t going to be able to make something like a spear. If we’re talking about complex toolmaking, such as flint knapping or tying a rock to a stick to use it as a hammer, there aren’t that many animals that can pull it off. There’s primates, elephants, birds, octopi, and I think that’s pretty much it. Insects might be able to do some stuff by massing together, but I don’t know how much.
Second, fire is OP because it lets you do things like harden wood, smelt metals, and just burn the hell out of stuff. That puts octopi out of the running: they’re pretty much limited to smacking coral and clam shells together because they live underwater. Octopi’s short lifespan will also work heavily against them. Insects are also kind of screwed: the square cube law means it will be very difficult to get a fire going, get it hot enough to melt metal, etc.
Now to elephants. They have strength on their side, but they only have one trunk as opposed to two hands, which will make some things less efficient. In addition, their sheer size limits population densities (which will make division of labor harder), and their diet of nutrition-poor plant matter means they have to spend a huge amount of time eating. Even with agriculture, this could limit their ability to dedicate time to inventing better tools. Other limitations of elephants include that they can’t climb very well, and their weight would make something like building a boat require much more resources. Humans can build a dugout canoe out of a single tree trunk and cross oceans with it. Elephants can’t.

实际上，（主宰者）可能还是人类。
首先，用一个术语来说——使用工具就是打破游戏规则。
没有能够有效制造和使用工具的人类体型的动物将无法像人类那样主宰这个星球。例如，尽管海豚很聪明，但它们不可能制造出矛这样的东西。如果我们说的是复杂的工具制造，比如打火石或把石头绑在棍子上当锤子用，没有多少动物能把应对它。有灵长类动物，大象，鸟类，章鱼，我想差不多就这些了。昆虫聚集在一起也许能做一些事情，但我不知道能做多少。
其次，火是绝杀。
因为它可以让你做一些事情，比如硬化木材，熔炼金属，以及燃烧所有的东西。这就把章鱼排除在外了：它们生活在水下，只能把珊瑚和蛤蜊的壳撞在一起。章鱼较短的寿命也会对它们造成很大的不利影响。昆虫也有点麻烦:二维三维定律意味着生火、加热到足以熔化金属等都将非常困难。

Now to elephants. They have strength on their side, but they only have one trunk as opposed to two hands, which will make some things less efficient. In addition, their sheer size limits population densities (which will make division of labor harder), and their diet of nutrition-poor plant matter means they have to spend a huge amount of time eating. Even with agriculture, this could limit their ability to dedicate time to inventing better tools. Other limitations of elephants include that they can’t climb very well, and their weight would make something like building a boat require much more resources. Humans can build a dugout canoe out of a single tree trunk and cross oceans with it. Elephants can’t.
Birds? They might pull it off: flight is a pretty big advantage. On the other hand, the bird species that have the dexterity to use tools aren’t all that strong. For example, I’m not sure how a raven would swing an axe with enough force to chop down a tree.

现在来谈大象。
它们的身体很有力量，但它们只有一副躯干，而不是两只手，这将使一些事情的效率降低。此外，它们庞大的体型限制了人口密度(这将使分工更加困难)，而它们营养贫乏的植物饮食意味着它们必须花费大量的时间进食。而来在农业领域，也会限制他们投入时间发明更好工具的能力。大象的其他限制包括它们不能很好地攀爬，它们的体重会让建造船只等事情需要更多的资源。人类可以用一根树干造出一艘独木舟，带着它穿越海洋。大象不能。
鸟?他们可能会成功:飞行是一个相当大的优势。另一方面，能够灵活使用工具的鸟类并不都那么强壮。例如，我不确定乌鸦如何挥动斧头，以足够的力量砍倒一棵树。

Other primates? Well, humans don’t have the agility of monkeys or the strength of gorillas, chimps, or orangutans, but we do have one thing going for us: we can walk and run upright at long distances and high speeds, with our hands off the ground and free to hold something like, say, a spear… and unlike other primates, which are covered in fur and have few sweat glands, we are almost hairless but have an extremely effective evaporative cooling system. Humans are pretty much the slowest land mammal anywhere near or size. If an animal wants to catch a fleeing human on open ground, it can usually do so with ease. On the other hand, if a human wants to catch an animal on open ground and that animal can find a place to hide, that animal is pretty much doomed, because we can keep running longer than almost any other animal. This means humans are much better suited to life in environments besides forests than other primates, and it’s much easier to clear a forest than to make one grow in a desert.
Other species could certain develop a civilization if they had similar intelligence to humans, but we have a combination of size, dexterity, omnivorous diet, and biomechanics which make it so that while some animals might be better at us at surviving in some environments, we can do an okay job pretty much anywhere.

其他灵长类动物?好吧，人类没有猴子的敏捷，也没有大猩猩、黑猩猩或猩猩的力量，但我们有一件事是有利的：我们可以在长距离和高速直立行走和奔跑，我们的手离开地面，可以自由地拿着像矛这样的东西……不像其他灵长类动物，它们满身是毛，汗腺很少，我们几乎没有毛，但有一个极其有效的蒸发冷却系统。人类几乎是速度最慢的陆地哺乳动物。如果一只动物想要在开阔的地方抓住逃跑的人类，它通常可以很容易做到。另一方面，如果一个人想在开阔的地方抓一只动物，而那只动物又能找到藏身之处，那这只动物就完蛋了，因为我们几乎比其他任何动物都能跑得更持久。这意味着人类比其他灵长类动物更适合在森林之外的环境中生活，而且砍伐森林比在沙漠中种植森林要容易得多。
如果其他物种拥有与人类相似的智力，它们肯定会发展出一种文明，我们人类的发展取决于我们的体型、灵活性、杂食性和生物力学结合在一起综合因素作用的结果，但其它一些动物可能在某些环境中生存得更好，但我们几乎在任何地方都可以做得很好。

Katie Bjorkman
Most species would die.
Humans have weird intelligence compared to other species. Our power lies in our ability to:
(1) Use our big brains to make tools. Tools are really hard to make and wield for most body types. If you woke up as a hoofed animal tomorrow, you would likely have trouble even turning the doorknob to leave your bedroom.
(2) Transmit knowledge via language and culture. Feral humans - i.e. humans with the same intelligence as anyone else but left without culture and language - are not highly functioning.

大多数物种将会死亡。
与其他物种相比，人类有着奇怪的智慧。我们的力量在于我们有能力:
1.用我们的大脑制造工具
对于大多数体型来说，工具真的很难制作和使用。如果你明天醒来时变成了一只有蹄的动物，你可能连转动门把手离开卧室都有困难。
2.通过语言和文化传播知识
野生人类——也就是说，拥有与其他任何人拥有相同的智力，但没有当前人类的文化和语言，就意味着没有高度的功能。

Here is the huge trade-off we humans have made: we suck at anything that isn’t taught to us. Seriously. Baby hawk falls out of nest, it can be reared (so long as it doesn’t imprint) and released into the wild and it will be just fine hunting and mating and nesting and migrating. But make that hawk have the intelligence of a human and, well, how are you going to teach it to hunt and mate and migrate?
Most species would be toast without complex, hard-wired behaviors via instincts. Giving them the intelligence of a human - which includes our incredible flexibility due to our lack of instincts - and most would die. Maybe the ragged survivors would invent language and figure out how to use hooves and claws and wings to make tools and use their language to transmit knowledge to their offspring. Maybe.

这是我们人类做出的巨大权衡：我们在任何没有教给我们的事情上表现都很糟糕。真的。小鹰从巢里掉出来，它可以被饲养(只要它没有留下印记)，然后被释放到野外，它会很好地狩猎、交配、筑巢和迁徙。但是让鹰拥有人类的智慧，你要怎么教它捕猎，交配和迁徙呢?
如果没有复杂的本能行为，大多数物种都会灭绝。如果赋予它们人类的智慧——包括我们由于缺乏本能而拥有的不可思议的灵活性——大多数都会死。也许狼狈的幸存者会发明语言，弄清楚如何用蹄子、爪子和翅膀制造工具，并使用他们的语言将知识传递给他们的后代。也许吧。

Michael Glenister
Quite a nightmare scenario.
When most people use the term animals, they tend to limit their thinking to mammals, and forget about sponges, jellyfish, flatworms, roundworms, earthworms, insects, spiders, crustaceans, squids, starfish, fish, amphibians, reptiles, and birds.
You might also want to consider numbers, and importance in the food web.
Now if they are going to act like humans, and have ambitions of ruling the world, then we are not going to fare well. The biosphere can do just fine without us, but there are other species, eg. ants, that it relies on. If one or two insect groups decide that we need to be eliminated, then there isn’t much we could do about it. Flies could contaminate all our food with pathogens, wasps or mosquitoes could hunt us down in great numbers either killing us directly or by disease, other insects could take out our food supplies, and still others could sacrifice themselves to neutralize our technology, eg. cover radiators to overheat vehicles. I haven’t even considered what the microscopic animals that live on and in us could do if they wanted to harm us.
My guess is some members of the Arthropods, simply because of pure numbers. However something lower and more crucial on the food chain could also take over by simply by shutting the food chain down, eg. if plankton made themselves unavailable as a food source.

果真如此的话，那真是一场噩梦。
当大多数人使用动物这个术语时，他们倾向于将自己的思维局限于哺乳动物，而忘记了海绵（一种海洋软体动物）、水母、扁虫、蛔虫、蚯蚓、昆虫、蜘蛛、甲壳类动物、鱿鱼、海星、鱼类、两栖动物、爬行动物和鸟类。
你可能还想考虑到数字和在生物链中的重要性。
现在，如果他们要像人类一样行事，并有统治世界的野心，那么我们就不会有好结果。没有我们，生物圈也可以过得很好，但还有其他物种，例如，蚂蚁是生物圈赖以生存的动物。
如果一两个昆虫群体认为我们需要被消灭，那么我们只能坐以待毙。苍蝇会用病原体污染我们所有的食物，黄蜂或蚊子会大量猎杀我们，要么直接杀死我们，要么通过疾病杀死我们，其他昆虫会夺走我们的食物供应，还有一些会牺牲自己来中和我们的技术，如，覆盖散热器让车辆过热。我甚至没有考虑过生活在我们身上和体内的微生物如果想伤害我们会做什么。
我猜是节肢动物的一些成员，仅仅因为数量（就足以制造麻烦）。此外，食物链中更低、更关键的东西也可以通过简单地关闭食物链来接管，如果浮游生物无法作为食物来源的话。

Unfortunately, i think Ants is going to rule the world.
To think human will continue ruling the world would be silly.
Food source
Your chicken, your fish, your cows etc are all smart now. They are not going to behave in such “peaceful” manner. They will retaliate and attack humans if they know and they will know we are going to eat them. They will not just gather around peacefully and will try to escape any confinement.
Fish will not swim at “dangerous” spots. They will not bite the baits any more. They might even figure out how to cut those nets that fisherman use to catch them, perhaps with the help of their friends such as crabs or lobsters, with their claws.
Your food source will most likely be mostly be plant based at this point.
All these aside, even at our current intelligent level, wiping out ants just from your house is very very tough. Not only they grow resistance to your poisonous bait, they breed fast too.

不幸的是，我认为蚂蚁将统治世界。认为人类将继续统治世界是愚蠢的。
食物来源
你的鸡，你的鱼，你的牛等等现在都很聪明。他们不会再以“和平”的方式行事。如果他们知道一切，他们会报复和攻击人类，他们会知道我们要吃掉他们。他们不仅会聚集在一起，还会试图逃离任何监禁。
鱼不会在“危险”的地方游泳。他们不会再咬饵了。它们甚至可能在螃蟹或龙虾等朋友的帮助下，用爪子弄清楚如何切断渔民用来捕捉它们的网。此时，你的食物来源很可能主要是植物。
抛开所有这些，即使以目前的智能水平，在你的房子里消灭蚂蚁也是非常非常困难的。它们不仅能抵抗你的毒饵，繁殖速度也很快。

They can live in almost anywhere. Behind your fridge. Behind your wardrobe. Underneath the ground, deep underneath the ground if necessary. At those hard to reach places at your roof and many more.
Once they have our intelligence, they will avoid those poison baits that you laid out. They will avoid dangerous spots and with their “hive mind”, they will work as a team, much better than humans.
Unless you sleep in a airtight place, ants can get in. They will get in underneath your door, through your ventilation. Any small holes, they will be able to get in.
Once in, they will just go through your nose and start chewing all the flesh they could.
You cannot defend against this.
There’s too much of them and they’re too small to be dealt with efficiently and they’re everywhere literally and hiding underground is so effective you can’t kill them without causing environment damage that affects you as well.

他们几乎可以生活在任何地方。在冰箱后面、你的衣柜的后面、地下，必要时可以在地下深处、在你屋顶上那些难以到达的地方等等。
一旦他们得到了我们的情报，他们就会避开你设下的毒饵。它们会避开危险的地点，凭借它们的“蜂群思维”，它们会像一个团队一样工作，比人类要好得多。
除非你睡在密闭的地方，否则蚂蚁会进来。他们会从你的门缝里进来，通过你的通风系统。任何小洞，它们都能进去。一旦进入，它们就会穿过你的鼻子，开始尽可能地咀嚼你的肉。对此你毫无防卫能力。
它们数量太多，体积太小，无法有效处理，它们无处不在，隐藏在地下是如此有效，你无法在不破坏环境并影响到自己的情况下杀死它们。
