Specific biological factors, including expanded cortical hierarchies and unique human gene repeat expansions like NBPF/Olduvai triplets, account for the advanced cognitive capacity of the human brain.

The analysis

The retrieved literature includes direct evidence that specific biological and genetic factors (such as NBPF repeat expansions and cortical specializations) underlie uniquely human cognitive capacities, supporting the claim.

The evolution and development of the uniquely human capacity for emotional awareness: a synthesis of comparative anatomical, cognitive, neurocomputational, and evolutionary psychological perspectives.. 2019. https://doi.org/10.31219/osf.io/sdbmr

This paper synthesizes comparative anatomical and neurocomputational perspectives, arguing that disproportionate cortical expansion and hierarchical processing levels account for unique human cognitive capacities.

This study demonstrates that specific genetic structures, such as tandemly organized NBPF 3mer higher-order repeats and Olduvai triplets, are vastly more abundant in humans and directly relate to enhanced human cognitive capacity.
