Is it possible that there is another intelligent species in our planet?

Question

I know that we humans are the only intelligent species on planet Earth but is it possible that there is another intelligent species on Earth, probably more intelligent than humans....

And I don't mean alien, I mean earthling.

Answer 1

I am sure that there mite be  monkeys are intelligent,dogs are they aren't as smart but in there own right they are but i know that squirrels are the least intelligent ugly things i know and seen :0)

Answer 2

Aren´t you contradicting yourself? You say we are the only intelligent species and then ask if there are any others.

To put your mind at rest it is safe to say that we are the only  technologically advanced species on this planet.

Answer 3

All species have their own intelligence. To rate them according to which is best is strictly human.

Answer 4

Yes, the graguans.

They are so advanced they manage to live among us without being noticed.

Answer 5

I think you need a broader definition of intelligent.   Apes, monkeys, whales, dolphins, dogs, elephants, horses.....many animals on this planet are intelligent.  They have societies, rules and families.  They communicate and teach.

Answer 6

The Common House Cat is the MOST intelligent animal on the planet...

It sleeps 17 hours per day, and it can get YOU, to feed it FRESH food whenever it wants...

Additionally, it can get you, to let it in and out of the house, at will...

The earth actually belongs to cats, but they do tolerate having humans as slaves...

Michel Montaigne said, "You couldn't know about your cat, in nine lives, what your cat already knows about you"...

Answer 7

Your dog or cat is one of the stupid non telepathic ones isnt it?

If you mean a hominid species then I suppose its possible some other species might have survived and be in hiding.

There are all those stories about metal working dwarves ... I sometimes wonder if one branch of neanderthals managed to learn metal working?

As for elves with "magical" powers probably a race of humans with psionic abilities explains those stories?

Many things are possible and speculation is pleasant but ACTUAL proof ... ah that's a whole other problem!

Answer 8

monkeys.  Didn't you see the number thing on the news lately?  they did better than the humans

Answer 9

wait a second, why do you say humans are the only intelligent species on earth?

did you know that whales know over 40 songs by heart, and that each of those songs contains more information than a large book?  i don't know a single human who knows 40 large books by heart.  

whales are obviously very intelligent, we simply don't understand what information they are exchanging with each other.

Answer 10

One species more intelligent than the other?

Well whatever race you will classify inventing globalization wasn't too smart was it.

Answer 11

It depends on how you define intelligence.

There are many types of intelligence, even among humans. Many animals, especially mammals, have a great deal of intelligence on our earth.

Scientists realize that animals such as whales, dolphins, seals etc. learn and teach language. They, and many other animals, have emotions and feelings and can plan and anticipate.

Humans are truly anthrocentric when they decide that their intelligence is always superior to other species. We certainly aren't intelligent when we form armies, or use our technology in ways that kill our own homes, resources, planet.
