Topic: Soldier Birds and Helpful Chimps: Is Altruism Genetic?
Soldier Birds: http://news.bbc.co.uk/1/hi/sci/tech/7350610.stm
"Like soldiers in combat zones, birds operate a sentry system to ensure their comrades are safe from attack.
By singing a "watchman's song", the pied babbler tells its group mates they are free to forage for food in Africa's Kalahari desert.
This is a rare example of truly altruistic bird behaviour, said Dr Andy Radford, of Bristol University, UK.
"The unselfish behaviour of the sentry is probably rewarded down the line. It's a win-win scenario," he said."
Altruism "in built": http://news.bbc.co.uk/1/hi/sci/tech/4766490.stm
"Infants as young as 18 months show altruistic behaviour, suggesting humans have a natural tendency to be helpful, German researchers have discovered.
In experiments reported in the journal Science, toddlers helped strangers complete tasks such as stacking books.
Young chimps did the same, providing the first direct evidence of altruism in non-human primates. "
