ok, in the 40's there was a rat experiment. A few were put into a large room, with adequate food....and that was it. They were allowed to procreate as they wished, and there was always enough food. Tucker was right...for awhile, the rats were fine. As they increased, rat behaviour DID change....teen male rats formed gangs and attacked the females and babies. Rat gangs had battles. The same as is happening to humans right now.

anthropologists have figured out that the average human can consider from 150-200 ppl as "us" .... everybody else is "them" ie strangers.
