Also, bonobos have a need reading glasses as they get older – Scientias.nl

Research shows that bonobos around their fortieth year of life seriously suffer from long sightedness.

When people grow older, they may have difficulties with reading the newspaper. They must have the newspaper further and further away from himself away, keeping to the letters to be able to read or reading glasses purchase. And now research shows that bonobo’s are the same ouderdomskwaaltje have, so write researchers in the magazine Current Biology. Of course that illnesses at bonobos are not reflected in the reading of the newspaper, but during the take care of each other’s fur.

Further away
The researchers did this discovery while observing a number of bonobos. "One day, I saw – together with other researchers – that the oldest male bonobo At the coat of Jeudi cared," says researcher Heungjin Ryu. "Had his arm stretch to Jeudi to be able to take care of and only when he has something in the coat took, he came closer to it with his mouth to remove it. It was funny to see how he the coat of Jeudi cared-for."

Further research
Further research showed that, however, is not the only impact was that in this way it coats well. The researchers studied fourteen wild bonobos, who are between 11 and 45 years old. They discovered that the bonobos in their arms as they grew older, still further extended during the care of the coat of a counterpart. The distance between the two animals took as the animals grew older, will increase exponentially.

Ancestor
"We discovered that wild bonobos around their fortieth symptoms of farsightedness show," says Ryu. This leads to their symptoms at about the same time as the hyperopia-symptoms of people: a relative of the bonobo. It suggests that the way in which the eyes, aging little has changed since the time that the common ancestor of the bonobo and humans lived. That’s extra remarkable when you consider that the lifespan of modern humans is much longer than that of bonobos.

The research suggests, furthermore, that hyperopia is not the result of a modern life in which we do a lot of reading or at a monitor staring at you. It seems, instead, a very natural and very old process.
