Humans may be gradually losing intelligence, according to a new study.
“The development of our intellectual abilities and the optimization of thousands of intelligence genes probably occurred in relatively non-verbal, dispersed groups of peoples [living] before our ancestors emerged from Africa,” said study author Gerald Crabtree, a researcher at Stanford University, in a statement.
Since then it’s all been downhill, Crabtree contends.

> Fluoride, a substance rampant water supply is lowering IQ and dumbing down the population.
> Pesticides, which are rampant among the food supply, are creating lasting changes in overall brain structure — changes that have been linked to lower intelligence levels and decreased cognitive function.
> Following 14,000 children, British researchers uncovered the connection between processed foods and reduced IQ.
