=== Cortical convolution ===
The folding of the brain’s surface, known as [[Gyrification|cortical convolution]], has become more pronounced throughout human evolution. It has been suggested that this increased folding serves as a neurological foundation for some of the brain’s most unique cognitive functions. As a result, the extent of cortical convolution may play a role in shaping individual intelligence within the human species. <ref>{{Cite journal|title = Neuroanatomical Correlates of Intelligence |journal = Intelligence|date = 2009-03-01|issn = 0160-2896|pmc = 2770698|pmid = 20160919|pages = 156–163|volume = 37|issue = 2|doi = 10.1016/j.intell.2008.07.002|first1 = Eileen|last1 = Luders|first2 = Katherine L.|last2 = Narr|first3 = Paul M.|last3 = Thompson|first4 = Arthur W.|last4 = Toga}}</ref>

An analysis published in 2019 found the contours of 677 children and adolescent (mean age 12.72 years) brains had a genetic correlation of almost 1 between IQ and surface area of the [[supramarginal gyrus]] on the left side of the brain.<ref>{{Cite web|url=https://www.the-scientist.com/news-opinion/brain-surface-area-reveals-overlap-in-genes--intelligence--evolution-65559|title=Brain Surface Area Reveals Overlap in Genes, Intelligence, Evolution|website=The Scientist Magazine®|access-date=2019-07-17}}</ref><ref>{{Cite journal|last1=Raznahan|first1=Armin|last2=Giedd|first2=Jay N.|last3=Lee|first3=Nancy Raitano|last4=Wallace|first4=Gregory L.|last5=Chu|first5=Alan|last6=Pritikin|first6=Joshua N.|last7=Seidlitz|first7=Jakob|last8=Liu|first8=Siyuan|last9=Clasen|first9=Liv S.|date=2019-04-17|title=A Comprehensive Quantitative Genetic Analysis of Cerebral Surface Area in Youth|journal=Journal of Neuroscience|volume=39|issue=16|pages=3028–3040|doi=10.1523/JNEUROSCI.2248-18.2019|issn=0270-6474|pmid=30833512|pmc=6468099}}</ref>
