why are humans taking over this world?

Question

as you see, humans' brains are dangerous. they exploit other living things and make themselves in dangerous (u see global warming) have you ever thought that if we stayed primitive, there will be no earth-damage?
why did humans' brains evolute the fastest?
will there any chance that someday another species of living things is evoluted as humans did and they take over this earth?

(imagine someday homo sapiens will be the MINOR creature and another species exploits homo sapiens as homo sapiens does in this world nowaday)

Answer 1

"(imagine someday homo sapiens will be the MINOR creature and another species exploits homo sapiens as homo sapiens does in this world nowaday)"

Sounds like the making of a good movie... Too bad Charlton Heston isn't acting anymore... He would make a good lead of,,, say,,, an astronaut who through time dialation returns to Earth in the distant future to find apes riding horses and hunting humans...

Answer 2

Human bodies became weaker as the brain grew stronger compared to other animals. Bigger brains made it possible to figure out ways to exploit everything else on earth and to defend against first large predators and now microscopic predators.

All of this contributed to more and more surviving offspring. From an evolution point of view, human brains made conquering and exploiting all other species possible.

But, now, the world is totally over-populated with no end in sight. The huge brains cannot figure this out and try to do something about it. Evolution and survival and the need to reproduce wins out over what common sense would dictate.

It may never be possible for another species to do what humans have done to earth. By the time humans have finished it off, there will be no more cheap fossil fuels to fuel another advancing (?) civilization.

Answer 3

It's geographical luck, we started out in Africa, then we moved to the middle east. In the middle east, we were able to learn how to farm. That brought us out of taking resources away, so we had to move. We moved to Europe and Asia, some to remote spots like Papua New Guinea or Japan. Then, we continued on and grew more food. Also, the main reason is that our greater ancestorst discovered something other than scavenging for fruit, they discovered that eating meat can help you become smarter, unlike monkeys (they're ancestors didn't discover so early as us). EX: a fox needs to know tactics to catch a rabbit, BUT the rabbit just needs to know how to run from the fox and get food.

Answer 4

We ain't. The biosphere is run by and for the benefit of bacteria and we are just along for the ride. If all the multicelled critturs from mushrooms to magicians disappeared tomorrow, the bacteria will still be here and would hardly have noticed us coming and going.

Answer 5

we r th most intelligent species. our brain-body size ratio is max. we learn things more quickly. 4m past u can c, all animals were equivalent( im talkin abou stone age). all animals including us had only 3 requirements FOOD, SPACE, SEX. Still its is th same requirements of other animals excluding us. in th past wen man learned to harness th resources in his vicinity for food,etc. he also learnt many peculier things also.
man has CURIOSITY also, he want 2 know everything. nd this lead 2 development. man developed th art 2 communicate, this is th key to share th information.
dnt worry my dear frend . i do agree that we r ruining our earth, but it will b total silly 2 go back to th stone age. we will make earth healthy again. KYOTO PROTOCOL is a nice example 4 it.

Answer 6

because we can so we do it is how the human brain works don't ask me why though good question though

Answer 7

because God created us in his own image,can you imagine that ! we are like him.and secondly we are difference than other lower animals,because of our higher brain.
