Dier, mens en empathie
| 29 nov.2009 |
Tot voor enkele jaren, op zijn hoogst twintig, was de algemeen geldende
opvatting dat dieren geen emoties hadden, in ieder geval niets dat leek op de
menselijke variant ervan. Voor een belangrijk deel werd dat ingegeven door de
christelijke opvattingen over de positie van mensen, dieren en moraal.
De laatste jaren gaan deze opvattingen is steeds hoger tempo overboord, onder
invloed van onderzoek maar wat betreft het grotere publiek vooral door de
verspreiding van informatie over het internet. Dat laatste is van belang omdat
de sterkere bewijzen van tegendeel zeldzaam zijn, en bij elkaar gebracht moeten
worden voor het onweerlegbare bewijs. Hier een voorbeeld van zo'n sterker bewijs:

Is this haunting picture proof that chimps really DO
grieve?

United in what appears to be deep and profound grief, a phalanx of more than
a dozen chimpanzees stood in silence watching from behind the wire of their
enclosure as the body of one of their own was wheeled past.
This extraordinary scene took place recently at the
Sanaga-Yong Chimpanzee Rescue Center in Cameroon, West Africa.
When a chimp called Dorothy, who was in her late 40s, died of
heart failure, her fellow apes seemed to be stricken by sorrow.
As they wrapped their arms around each other in a gesture of
solidarity, Dorothy's female keeper gently settled her into the wheelbarrow
which carried her to her final resting place - not before giving this much-loved
inhabitant of the centre a final affectionate stroke on the forehead.
...
Until recently, describing scenes like this in terms of human
emotions such as 'grief' would have been dismissed by scientists as naive
anthropomorphising.
But a growing body of evidence suggests that 'higher'
emotions - such as grieving for a loved one after death, and even a deep
understanding of what death is - may not just be the preserve of our species.
Chimpanzees ... and the closely related Bonobos maintain
hugely complex social networks, largely held together by sex and grooming.
They have often been observed apparently grieving for lost
family and tribe members by entering a period of quiet mourning after a death,
showing subdued emotions and behaviour.
And such complex emotions are not the preserve of primates or
even mammals. Just this month, for instance, Dr Marc Bekoff, an ethologist at
the University of Colorado, reported evidence that magpies not only appear to
grieve for their dead but carry out something akin to a funeral ritual.
In one instance, a group of four magpies took it in turns to
approach the corpse of their dead comrade.
Two of the birds then flew off to return with a piece of
grass, which they laid down by the corpse. The birds then stood vigil.
In fact, there is a large body of anecdotal evidence that
corvids - the group of super-bright birds that include crows, magpies and rooks
- engage in many sophisticated social rituals.
But the most famous nonhuman death rituals are those of
elephants, who will often spend days guarding a dead body, gently prodding the
remains with their trunks and giving the impression of being lost in grief.
Elephants are highly social, long-lived and intelligent
animals, whose excellent memory is no myth.
It is perhaps unsurprising that the loss of a member of the
clan produces an emotional reaction.
The evolution of human death rituals is lost in the mists of
time. There is some evidence that now-extinct hominid species such as the
Neanderthals appreciated the significance of mortality, burying their dead and
even scattering the graves with flowers.
Seeing a group of chimpanzees, our closest relatives,
apparently paying a sad and heart-rending tribute to their much-loved lost
sister gives us, perhaps, a window on how this deepest and most fundamental
emotion evolved in our own ancestors.
