Hi guys 👋  in this blog lets see how humans communication differs from animals and about body language. 
Their or lot of way to communicate speaking, singing, clapping, hooting, even animals communicate with one another in ways different from the human only humans can express they thoughts and feelings in word because of our superior brain both humans and animals also communicate through body language sometimes we don't use both but make gestures like Traffic sign or simple moments of the hand in order to communicate. 
Why can human speak, but not animals ?
A lot of organs such as lungs larynx mouth pharynx tongue teeth and brain participate in the speaking process all though animals poses all these organs structure is different from that in the human for speaking it is important to properly control the process involved mainly breathing this is done for us by our brain first the hair is inhaled and then deviated through the Larynx from the lungs it as small muscles called the vocal cord when the air passes through the stretched elastic vocalfolded causes them to vibrate producing sound the teeth tongue gums and lips then form the words. 
How do animals communicate ?
Dog bark, growl whine. Deer bell, mice squeak. When bee  has detected it informs the other bees by a kind of a dance and whale inform Each Other by means of whale song there sound can be heard in water from several 100 KM the communication of the Wales has increasingly become difficult because they are so many other sound in the oceans now like those of ships or of oil rigs in general animals of the same species communicate with one another without a problem between species their could be misunderstandings for example a cat pores with satisfaction but that dog meeting that the cat is snarling at it. 
What is body language?
Both humans and animals communicate a lot through their body poster a cat when angry humps it bad and it can ruffles up so that it appears bigger and more dangerous in this way it once it's opponent not to come near humans from when in doubt and smile when happy we use the Thumbs up or the thumbs down sign as common gesture of approval or disapproval by extending the thumbs upward or downward we also make you software Universal sign language we know what an index finger on the lips or a waving hand is trying to tell us but watch out sign do not mean the same all over the world if you make an O with the index finger and the thumbs it means okay in USA but at other place it is an insult.
