Natural Born Heroes

A 200,000 year old jawbone tells the story of an elderly woman who was kept alive thanks to the kindness of her companions. Is this jawbone the oldest evidence of human kindness? From this first known example of human compassion to modern day heroes, the final programme in the Human Instinct series explores the most complex of instincts. The instinct to put others first. Blood Ties The mother’s drive to protect her children is the most powerful heroic instinct we know. Cindy Parolin showed no hesitation when she leapt to the defence of her 6 year old son. Attacked by a cougar, Steven was saved by his mother’s incredible bravery as she wrestled with the animal for hours while he was dragged to safety by his brother and sister. But what is it that drives this incredible behaviour? Having children is a way of ensuring our genes are passed on to the next generation. Humans usually have just one child at a time, so they are prepared to do virtually anything to ensure their children are safe. But this protective instinct also expands to the rest of our family. And the more genes we share, the more likely we are to put ourselves out for someone. In a unique experiment, scientist Dr George Fieldman proves this point. People will hold their breath longer for their parents, children or siblings - who share half their genes - than they will for their grandparents, uncles or aunts- who share only a quarter. People will hold their breath longer underwater for more closely-related family. Fast Friends But unlike many animals, humans are also willing to risk everything for people who aren’t related to them. Al Rascon received the medal of honour for his actions in the Vietnam war. He ran into a hail of bullets, risking death, to rescue his injured friend. How has this self-sacrificing instinct evolved? It appears humans have quite a lot in common with vampire bats. These tiny creatures must feed often to survive, and it is not that easy
