Intelligence is believed to be among the conditioned genes that have to come from the mother. Laboratory studies using genetically modified mice found that those with an extra dose of maternal genes developed bigger heads and brains, but had little bodies.

Like most aspects of human behavior and cognition, intelligence is a complex trait that is influenced by both genetic and environmental factors. Intelligence is challenging to study, in part because it can be defined and measured in different ways.

Where does real intelligence come from?

“General intelligence originates from individual differences in the system-wide topology and dynamics of the human brain,” Barbey tells The Scientist. General intelligence originates from individual differences in the system-wide topology and dynamics of the human brain.
