You scratch my back... Presentation Transcript

An animal is said to be altruist when its behaviorbenefits other individuals, sometimes at a cost of its own well-being.
Sebastião Salgado
Animal altruism is most obvious in kinrelationships, but may also be evident among wider social groups.
In “The Selfish Gene”*, Richard Dawkins puts forth three strategies of reciprocal altruism: Suckers, Cheats and Grudgers. *Chapter “You scratch my back, I’ll ride on yours”
Let’s say that a bird (B) has a parasite on the topof his head and needs another bird (A) to remove it. A pulls it off him.A is a sucker and grooms others indiscriminately.
Later, A has a parasite on his head and seeks outB in order that B may pay back his good deed. B simply turns up his nose and walks off.B is a cheat, an individual who accepts altruism from others, but never returns it.
But now, suppose there is a third strategycalled Grudger. Grudgers groom strangers and individuals who have previously groomed them. However, if any individual cheats them, they remember the incident andbear a grudge: they refuse to groom that individual in the future.
*http://www.all-creatures.org/stories/a-love.html
A swallow is injured and the condition is fatal.She was hit by a car as she swooped low across the road.
Her mate brought her food and attended to her with love and compassion.
He came back with food again but found her dead.He tried to move her... A rarely-seen effort for swallows!
Aware that she is dead and will never come back, he cries out.
He stood beside her, crying out.
Finally aware that she will never return,he stood beside her body with sadness and obvious sorrow.
Sebastião Salgado IN MEMORY OF MY SISTER GLÓRIA WITH LOVE AND COMPASSION
