i dont think we should be able to use polyworld. The creatures in Polyworld will Develop a human level intelligence. We should not be in control of these creatures, its not humane.

I sure do wish that all of us could have a copy of this program so that we could see what we could do with the program...

yeah, it would be nice if they had a video form of abstract or a 10 minute compressed form of what they want to say.

I think that you're trying to apply a strong, philosophical definition of altruism (pure selflessness with no benefit) to determine whether a phenomenon is altrusistic or not. That's not really the sense in which biologists use the term. Note, before, that I said "no immediate payoff" - yes, there may ultimately be a benefit to the individual (as in the case of reciprocal grooming), but expending effort in such a way has a high exposure to risk; freeloaders can be groomed without ever...

Also I would argue shouting doesn't necessarily put the animal at risk. It draws attention, sure. But the predator has likely already spotted the group, and if it will begin persue it will most likely go for the closest/youngest/lonely prey, not based on shouting or not.As for vampire bats, I did a bit of reading and it seems like they do exhibit a form of altruism. However vampire bats in that case are the exception, not the rule.

Grooming benefits the animal performing the grooming. It raises it social status (mating), and makes it more likely it will get groomed by others (status). Shouting as a warning help save the group. The group has many advantages for the individual. This can be compared to a human enlisting the army to fight a war to protect his country. He doesn't do it in the name of sacrifice, he does it because he knows if his country will not be defended his way of life / family / freedom be destroyed.

Vampire bats regurgitating blood to feed others who didn't manage to feed themselves on a particular night, bird and monkey species who give out a cry to warn others of an approaching predator, attracting the predator to themselves, apes and birds that groom one another to remove parasites - all of these activities benefit one individual (the receiver) at cost to another (the one providing the 'favour').

Can you give such an example?
