Cremona, 25 giugno 2008. Oggi nella nostra città si ritroveranno volontari dalle province italiane bagnate dal fiume Po per dar vita al primo di una serie di appuntamenti organizzati per la pulizia delle rive [banks] del fiume più lungo d’Italia. L’anno scorso era toccato al Tevere e due anni prima all’Arno, ora anche il nostro fiume potrà avere le attenzioni che merita e di cui ha un estremo bisogno. Oggi Cremona e poi, durante luglio e agosto, i volontari si ritroveranno a Mantova, Parma, Piacenza, Reggio Emilia e Ferrara, per un’operazione che porterà più di duemila volontari di varie associazioni emiliano-romagnole e lombarde a dedicarsi al fiume. L’intenzione è quella di restituirlo alle persone, di farlo tornare un luogo dove incontrarsi, dove poter prendere il sole e, per chi non ha paura delle sue correnti, di fare una nuotata. Oggi purtroppo, quelle che una volta erano le spiagge dei poveri, di quelli che non potevano permettersi le vacanze al mare, assomigliano più a una discarica di rifiuti. Negli anni precedenti più di quattro tonnellate di rifiuti erano state raccolte nell’operazione di pulizia del Tevere e dell’Arno: per il Po ci si aspetta che almeno venti tonnellate di rifiuti verranno rimosse dai volontari in questi due mesi. Per chi volesse dare una mano, il ritrovo è alle 9:00 di oggi davanti al Duomo: i lavori continueranno per tre giorni, fino a domenica 27 alle 17:00. Si prevede la racconta di _____ tonnellate di rifiuti per la pulizia del Po. a. quattro b. venti c. non si sa con precisione
The Theory of Inclusive Fitness
If a blackbird's primary instinct is self-preservation, why does it risk death in order to warn others in the flock that a hawk is approaching? Why does a young man, who has his whole life ahead of him, jump in front of a speeding bus to save a child? Are these behaviors spiritually altruistic, or is there some biological explanation for self-sacrifice? The traditional theory of evolution in the early 1900s proposed the idea of "survival of the fittest." This idea made evolution seem like a competition between individual creatures, and it did not explain why animals sometimes make sacrifices to help each other. However, in 1964, W. D. Hamilton proposed the theory of "inclusive fitness," which seems to explain the mystery of self-sacrifice. The instinct to protect one's young, or one's family, is easily understandable in terms of evolution. According to Hamilton, an organism may contribute to its own chances of passing on its genes if it helps others that share the same or similar genes. This same helpful behavior can be extended to other, more distantly related members of the same species. Hamilton's theory of inclusive fitness says that not only do we have an instinct to protect our own young, but we also have an instinct to protect the reproductive success of others, as long as they are somewhat related to us. The theory of inclusive fitness suggests, of course, that the probability of the young man heroically rescuing the child will decrease as the degree of relatedness between him and the child decreases. But if the child is his own, the likelihood of him helping is far greater than if the child is not in his family.
