what creature will take over the world if human extinct??

Answer 1

since u like aliens so much , I will say aliens

Answer 2

As I understand it, humans are really the first species ever to "take over the world". Throughout every era, different species may have been at the top of the ecological food chain, or have had no natural predators, but I believe that an animal would have to evolve to the point of simply repeating the origins of our species, probably a large mammal such as the great apes.

So in answer to your question "what creature will take over the world if humans went extinct?"...I would have to say, strangely enough, humans.

Answer 3

About every hundred million years there's a major extinction and everything practically starts over again. The dinosaurs didn't survive the last one, and the mammals took over. It depends on the type of catastrophe that hits. The dinosaurs didn't suvive the Yukatan asteroind because they couldn't burrow underground and hybernate like small mammals at the time could. If the next catastrophe is a nearby supernova, maybe the insects can survive high amounts of radiation better than mammals.

Answer 4

None will take over.
They will reach a balance where all of them live in some type or harmonious, symbiotic relationship.
If, at some point, one were to get out of hand (in a strictly numerical way), some predator would arise and take care of them. Or their own overpopulation would cause their demise due to a lack of food, a increase in disease, etc...

Answer 5

One day in about 1 billion years A young grub will ask in a classroom if mammals ever ruled the Earth. The teacher will shout, "That is blasphemy, every one knows that God created Cockroach in his own image!!!"

Answer 6

Probably cockroaches. They've been around for several hundred million years and they are most remarkably like our current World leaders.
