Study Shows How Intelligence In Humans First Evolved
AUTHOR

In two papers published today in ‘Nature Neuroscience’, researchers have identified the key genes involved in the evolution of intelligence and complex behaviours in humans and other mammals.

The same genes that gave rise to higher mental function are also responsible for a number of brain disorders, the results reveal, suggesting that the evolution of intelligence came at the cost of mental illness.

The discovery pinpoints when in history the genes that enable us to think and reason evolved, giving us the ability to learn complex skills, analyse situations and have flexibility in how we think.
