Clint Eastwood's movie, 'The Good, The bad and The Ugly', became the instrument of a study to understand the secrets of brain evolution.
Researchers scanned the brains of 24 people and four rhesus monkeys while they watched-'The Good, The Bad and The Ugly', to study the evolution of the brain.
Earlier research had assumed that human brains and monkey brains were almost similar, except that human brains were bigger. Functions of the brain were pretty much similar to monkeys.
This discovery may be the foundation of a precise explanation of our evolution.
