Do all living things possess intelligence?
Well, 'life' and 'intelligence' are pretty arguable things. Defining whether something is 'alive' is a philosophical problem left unsolved since... forever (even now. see viruses). As for intelligence, all 'living' things don't necessarily possess intelligence. A tree is alive.. not necessarily possessing intelligence but does function to stay alive. Plankton don't have intelligence, but they have photoreceptors to trigger electric pulses to tell it to move when it needs to survive.

So, yes, 'living things possess intelligence'.

If yes, then how animals are differ from us?
1) Big syntax error in that question..
2) We are animals. Take a basic biology class. There are different types of animals.. Can you tell me how a tiger differs from a human?

Just a minor suggestion.. think a little more carefully into what you are thinking. Life and intelligence have their controversies.. animal differences are obvious between species.

It is my non-expert opinion that true life and/or intelligence is the fear of mortality. Therefore although not nessecarily sentient a tree is alive on the grounds that they do create defense mechinisms to protect their own life. Further, to take a small step into the animal kingdom, although ants are a "hive mind" if you threaten an individual ant it goes into a defensive state where it tries to escape that threat. Human beings are (with the exception of Lemmings(There may be more, but I only know of lemmings)) the only animal on the planet that will willingly destroy our own lives through suicide, yet even those among us who are suicidal are terrified of our death.

Simply stated, Intelligence is no more than the fear of dieing.
