Random Genetics!!
A British anthropologist had been living with an isolated African tribe.
He was one of the few Europeans to ever have contact with the tribe.
Through years of study, the anthropologist learned the tribe's
language and was living with them to better understand their culture.
One day, a woman in the tribe gave birth to a white baby.
The tribe elders were furious. They thought the anthropologist had
betrayed their trust and seduced the woman.
The tribe leader decided to confront the European and demand he explain his actions.
The anthropologist denied ever being intimate with the woman.
"But how is it that her baby is white?" the leader asked.
"You are the only white man we have seen in years!"
Confronted with that simple fact, the anthropologist scrambled.
He turned to a field where the tribe's sheep were grazing.
He pointed to one black sheep among the white animals.
"See! Nature is abundant with diversity. Through a random mix of genetics,
you get seemingly inexpiable variations in colour.
That's how a flock of white sheep could produce a black sheep."
The leader paused. He looked at the black sheep and then back to the anthropologist.
"OK. I won't say anything about the white baby if you don't say anything about the black sheep."
