No family outing would be complete without a squabble over directions. Now conservations have discovered such rows are just as common among herds of elephants thundering across Africa“s vast plains.
It is one of several striking features of their intriguing social system which suggest their behavious is remarkably similar to that of humans.
In the wolrd“s longest continuous study of elephants， researchers who have spent nearly 40years observing their behaviour at the Amboseli National Park in Kenya say the animals use complex commuincations in what appear to be discussions over which route to take.
They also use body language and sounds in other distincly human ways， rubbing shoulders or entwing trunks as a greeting and folding their trunk under their tusks an an invitation to paly.
A calf may reassure itself be sucking its trunk， just like a human baby sucks its thumb.
And female elephants sometimes appear to flirt by glancing over their shoulders at suitors with their eyes opened wide.
Negotiations over directions often begin with a common signal known as the “let“s go“ rumble.
The elephants then engage in lengthy exchanges umtil a consensus is reached and the herd moves off in the chosen direction.

“It“s wonderful to watch and a real process of negotiation.“she said.
The study provides further evidence for elephants“capacity for empathy. They have long been known to display human traits such as grief， but the research shows they may also wince at each other“s pain.
In one example， when a young elephant approached an electric fence， an older famale “looked alarmed， waiting for it to get zapped“， said Cynthia Moss， who founede the Amboseli Elephant Research Project in 1972. She told New Scientist magazine:“Her posture and blinking eyes showed she was wincing.“
Other elephants have been seen puliing out teanquillser darts from fellow herd members. Two were once seen propping up another between them after after it was teanquillised.
The researchers， who have tracked 2，500 elephants，argue that the animals have brain power comparable to apes， but not as advanced as dolphins or humans.
“One thing we can say with confidence is tha elephants live in a very complex social system.“ said Miss Moss. “The core is the family unit， made up of related females and their offspring. But there are layers of relationships berween the families. resulting in bond groups， clans and sub-populations.“
