Neoteny Argument
Human populations display an intra-species gradient in neoteny; this gradient is empirically measurable, heritable, and predictive of cognitive and institutional phenotypes after controlling for environmental variance.
-
craniofacial morphology (Brace et al., 1991; Harvati & Weaver, 2006)
-
growth curves and skeletal maturation (Bogin, 1999)
-
prefrontal cortex development tempo (Petanjek et al., 2011)
-
sexual dimorphism and androgen receptor sensitivity (Puts et al., 2016)
-
increased neocortical size and plasticity
-
enhanced executive function
-
reduced reactive aggression
-
greater investment in learning
-
general intelligence (g) (Lynn & Vanhanen 2012; Rindermann, 2018)
-
executive function (Ardila et al., 2005)
-
impulse control (Moffitt et al., 2011)
-
reaction time (Woodley et al., 2015)
-
delayed gratification / time preference (Wang et al., 2016; Daly & Wilson, 2005)
-
rule-following behavior (Henrich, 2020)
-
contract enforcement (La Porta et al., 1999)
-
low corruption and high institutional trust (Inglehart & Welzel, 2005; Rothstein & Uslaner, 2005)
-
cooperation in large-scale, impersonal environments (Turchin et al., 2013)
-
Pubertal timing: h² = 0.50–0.80 (Towne et al., 2005; Silventoinen et al., 2008)
-
Brain maturation tempo: h² ~ 0.80 (Lenroot et al., 2009)
-
Craniofacial morphology: h² 0.40–0.80 (Johannsdottir et al., 2005)
-
intelligence: h² 0.50–0.80 (Plomin & Deary 2015)
-
executive function: h² 0.40–0.60 (Friedman et al., 2008)
-
impulsivity / self-control: h² 0.40–0.70 (Beaver et al., 2009)
-
Twin/adoption studies: cognitive & behavioral traits track inherited tempo, not household environment (Bouchard, 2004)
-
Transnational migration studies: life-history traits persist across cultural environments (Nettle, 2011)
-
GWAS data: tempo-related traits (height, puberty, schooling duration) correlate with polygenic scores (Okbay et al., 2016; Day et al., 2017)
-
operationally measurable,
-
cross-domain testifiable,
-
falsifiable,
-
and robust under adversarial controls.
-
empirically measurable,
-
genetically influenced,
-
developmentally causal,
-
behaviorally expressed,
-
institutionally consequential,
-
and decidable under the Natural Law framework.
Any model denying these relationships must reject established findings across evolutionary biology, behavioral genetics, developmental neuroscience, anthropology, and NL’s requirement for operational, measurable, testifiable categories.
