Monkey IQ and the evolution of intelligence
Scientists at Harvard have developed a pseudo-IQ test for monkeys which shows that monkeys display consistent levels of intelligence across a variety of cognitive tests.
Banerjee's team ranked the 22 monkeys across all 11 tasks and found that the same animals tended to perform similarly well across all the tests. When her team calculated an IQ score for each monkey, the smarter monkey bested the less intelligent monkey two-thirds of the time for any given test.
"This is a difficult study to undertake, and this team should be commended for doing it so well," says Robert Deaner, a psychologist at Grand Valley State University in Allendale, Michigan. He says the new work "really strengthens the argument" that general intelligence has a long evolutionary history.
