In addition to cranium and brain size, researchers were privy to exciting observations. First, they identified six brain areas that contained only maternal or paternal genes. Second, they found no paternal genetic material within the cerebral cortex – the brain area responsible for executive functioning, such as language, planning, logical reasoning, and advanced thinking.
The idea that mothers disproportionately influence a child’s intelligence is not new. In 1984, the University of Cambridge studied both brain development (termed “co-evolution) and genomic conditioning. Cambridge sciences ultimately concluded that maternal genetics contribute more to the thought centers of the brain.
Fast-forward to today, and similar findings have occurred, like the experiment described above.
In one particularly noteworthy study, researchers at a governmental agency in Scotland followed a group of 12,686 people aged 14 to 22. Researchers would interview the subjects each year while observing intellectual development while considering various factors, from education to ethnicity. The scientists conclusively state that the mother’s IQ was the best predictor of intelligence.
Final Thoughts: Mothers Pass Intelligence on to Their Children
Without a doubt, researchers will continue to evaluate and challenge the findings of this and related studies about intelligence. As mentioned, some people will not accept scientific research that claims the development of intellect.
However, if one conclusion can be reached, it’s this: mothers significantly influence their children’s cognitive abilities.
And it isn’t just genetics, either, far from it. Nourishment and nurturement of a child directly influence their intellectual growth – two responsibilities mainly overseen by the mother. Furthermore, the special bond between a mother and child stimulates them to explore the world and navigate problems.
In conclusion, women play a much more significant role in children’s intellectual development than most genetic experiments previously thought. However, the findings of these and other studies seem to bolster the notion that our moms give us our brainpower.
Thanks, Mom!
