“…Some researchers have used life history strategies (i.e. unified clusters of traits; Hertler et al, 2018; Pianka, 1970) to understand these decisions and outcomes. However, it is unclear whether humans actually possess unified clusters of individual traits associated with life history strategies (de Vries et al, 2016; Zietsch & Sidari, 2019).…”

Young adults have to make important fitness-related decisions regarding how they will invest their time and energy into parenting, mating, and somatic investments. Using an adaptive, evolutionary lens, we examined the role of personality traits on the appeal of, and engagement with, these 3 forms of investment. We also examined the potential indirect role of appeal in linking personality to engagement. We chose to study 516 young adults whose life stage coincides with compromises between these 3 forms of investment. Our data showed that certain HEXACO traits were uniquely associated with parenting (e.g., higher E, X, and lower C), mating (e.g., lower H, higher X, lower C, and higher O), or somatic (e.g., lower H, higher E, X, A, and C) appeal and engagement. Additionally, some traits that were associated with parenting engagement were also related to somatic appeal. In contrast, some traits that were associated with parenting engagement were inversely related to mating appeal and viceversa. Our study therefore depicts the flexibility of personality traits in their associations with investment decisions. This malleability in personality traits could allow for investment decisions that could lead to adaptive outcomes across different contexts. Public Significance StatementPersonality traits can play a significant role in delineating individuals' important life decisions, such as parenting, mating, and establishing oneself. Our study showed that specific personality traits relate to how individuals perceive these decisions, which can then be associated with engagement in 1 or more of these important decisions. This study provides some important insight into how personality is linked with potentially adaptive decisions individuals make regarding their time and resources.

“…As applied in psychological research ( Del Giudice et al, 2016 ; Nettle and Frankenhuis, 2020 ), life history theory offers a meta-theory ( Hertler et al, 2018 ) and a mid-level established framework to interpret mainly childhood experiences, trait covariation, and individual differences in allocation of evolutionarily relevant resources ( Del Giudice et al, 2016 ; Krams et al, 2019 ; Nettle and Frankenhuis, 2020 ). Organisms have limited amounts of time, energy, and resources at their disposal, that need to be allocated among competing demands.…”

COVID-19 Pandemic on Fire: Evolved Propensities for Nocturnal Activities as a Liability Against Epidemiological Control

et al. 2021

Humans have been using fire for hundreds of millennia, creating an ancestral expansion toward the nocturnal niche. The new adaptive challenges faced at night were recurrent enough to amplify existing psychological variation in our species. Night-time is dangerous and mysterious, so it selects for individuals with higher tendencies for paranoia, risk-taking, and sociability (because of security in numbers). During night-time, individuals are generally tired and show decreased self-control and increased impulsive behaviors. The lower visibility during night-time favors the partial concealment of identity and opens more opportunities for disinhibition of self-interested behaviors. Indeed, individuals with an evening-oriented chronotype are more paranoid, risk-taking, extraverted, impulsive, promiscuous, and have higher antisocial personality traits. However, under some circumstances, such as respiratory pandemics, the psychobehavioral traits favored by the nocturnal niche might be counter-productive, increasing contagion rates of a disease that can evade the behavioral immune system because its disease cues are often nonexistent or mild. The eveningness epidemiological liability hypothesis presented here suggests that during the COVID-19 pandemic, the evening-oriented psychobehavioral profile can have collectively harmful consequences: there is a clash of core tendencies between the nocturnal chronotype and the recent viral transmission-mitigating safety guidelines and rules. The pandemic safety protocols disrupt much normal social activity, particularly at night when making new social contacts is desired. The SARS-CoV-2 virus is contagious even in presymptomatic and asymptomatic individuals, which enables it to mostly evade our evolved contagious disease avoidance mechanisms. A growing body of research has indirectly shown that individual traits interfering with social distancing and anti-contagion measures are related to those of the nocturnal chronotype. Indeed, some of the social contexts that have been identified as superspreading events occur at night, such as in restaurants, bars, and nightclubs. Furthermore, nocturnal environmental conditions favor the survival of the SARS-CoV-2 virus much longer than daytime conditions. We compare the eveningness epidemiological liability hypothesis with other factors related to non-compliance with pandemic safety protocols, namely sex, age, and life history. Although there is not yet a direct link between the nocturnal chronotype and non-compliance with pandemic safety protocols, security measures and future empirical research should take this crucial evolutionary mismatch and adaptive metaproblem into account, and focus on how to avoid nocturnal individuals becoming superspreaders, offering secure alternatives for nocturnal social activities.

“…Hence, species–environment matching influenced the distribution of animals, with geographical barriers limiting the migration of non-native species lacking the necessary traits to establish into a new environment (Wallace, 1876). These classifications capture covariation among taxa in response to the local conditions whereby, rather than viewing the local ecology operating independently on each native species, environmental pressures generate a cascade of effects among entire symbiotic species assemblages (Hertler, Figueredo, Peñaherrera-Aguirre, Fernandes, Woodley of Menie, 2018).…”

Controversial theories have been advanced (e.g., Rushton, 1985, 2000) relating “race” to human life history strategy: (a) different human populations (“races”) evolved in different physical and community ecologies; (b) these ecologies should at least partially determine the selective pressures shaping the evolution of human life history strategies in different parts of the world; ergo (c) different human populations (“races”) should be associated with different modal life history strategies. Although the argument seems plausible in its stark logical form, there were several limitations in operationalization: (a) the traditional “Big Three Races” used (Caucasoid, Mongoloid, and Negroid) do not correspond very closely to the five or six major population clusters identified by modern human genetics; (b) these “races” are neither discrete nor mutually exclusive, having many zones of overlap and interbreeding, making geographical boundaries fuzzy and imprecise; (c) fixing the “race” issue will still not directly address the fundamental premise of the theory that human life history strategy is largely determined by ecological factors. We therefore divided a sample of 141 national polities into zoogeographical regions instead of conventionally defined “races.” We only used regions for this analysis that were still inhabited mostly by the aboriginal populations that existed there prior to the 15th century AD. Although obtained by different procedures than those used originally by Rushton, these produced results that were surprisingly convergent with the basic premise underlying the original hypotheses.
