What's the essential difference between Human and Animal ?

The obvious differences are there. They do not talk due to the vocal cord differences. They do not lie!! They can withstand the cold where we put on clothing. They have never sinned. They have often learned to manipulate people or things larger than themselves for their own benefit and in a way so that the people don't seem to mind.

some time human behavie like animals but animals never befaive like humans.

theres not a big difference between the two. we ahve a more developed brain and body.

The speech and the behavior are the essential factors that differentiate human and animal.

men can think and feel.. of course animals too, can feel, what i mean is humans have emotions. they fall in love.. humans have a common sense and can distinguish wrong from right.. if they fail to think effectively, feel love, and lost his senses, they become animals. and sometimes more than animals...

human: animal: have brain have brain can think about something cannot think at all good about good or good or bad bad

I think feet and body hair are the only differences that I can come up with.

The brain. Animals like chimps and apes have many physical traits similar to humans, but without the human thought and reasoning abilities, they can't do what humans do.
