abstract Global exposures to air pollution and cigarette smoke are novel in human evolutionary history and are associated with at least 12 million premature deaths per year. We investigate the history of the human exposome for relationships between novel environmental toxins and genetic changes during human evo- lution in six phases. Phase I: With increased walking on savannas, early human ancestors inhaled crustal dust, fecal aerosols, and spores; carrion scavenging introduced new infectious pathogens. Phase II: Domestic fire exposed early Homo to novel toxins from smoke and cooking. Phases III and IV: Neolithic to preindustrial Homo sapiens incurred infectious pathogens from domestic animals and dense com- munities with limited sanitation. Phase V: Industrialization introduced novel toxins from fossil fuels, industrial chemicals, and tobacco at the same time infectious pathogens were diminishing. Thereby, pathogen-driven causes of mortality were replaced by chronic diseases driven by sterile inflammogens, exog- enous and endogenous. Phase VI: Considers future health during global warming with increased air pol- lution and infections. We hypothesize that adaptation to some ancient toxins persists in genetic variations associated with inflammation and longevity.

Cause of Death: Chimpanzees of Gombe, Mahale, and Taï; seveen groups of hunter-gatherers and forager-horticulturalists (Gurven and Kaplan 2007; Gurven and Gomes 2017). Chronic degenerative diseases of aging (cancer, heart disease) are major causes of death in industrialized humans, but are not well defined for chimpanzees or traditional humans. Postmortem findings for older chimpanzees are from captives; there are almost no autopsy data for traditional preindustrial humans. Heart failure of aging chimpanzees is generally nonischemic, based on captives maintained on a healthy diet (Varki et al. 2009). Although coronary artery atherosclerosis is unstudied in wild chimpanzees, aortic atherosclerosis was reported in a small sample of adult wild chimps killed in the Congo (Vastesaeger and Delcourt 1961). However, some early studies noted ischemic deaths in association with elevated chlolesterol (Finch and Stanford 2004:Table 3A, Appendix 4). Tsimané also have negligible ischemic deaths, with slower cardiovas- cular aging than industrial populations (Kaplan et al. 2017). Life expectancy: Young adult chimpanzee (Bronikowski et al. 2016; Wood et al. 2017), human Tsimané (Gurven et al. 2007), and U.S. (National Center for Health Statistics 2016).

1. Warming and insect- The expansion of insect-borne infections with global warming is described in rigorous models borne diseases (Wang and Zou 2018), e.g., dengue, yellow fever, and Zika by Aedes aegypti. Malaria is expanding globally (Flahault et al. 2016; Hundessa et al. 2018). The number of mosquito Disease Danger Days has increased in the U.S. since 1970, e.g., by 47 days in San Francisco (Langer et al. 2018). Arctic warming is associated with faster mosquito development (Culler et al. 2015). Lyme disease is expanding across temperate zones with the tick Ixodes scapularis (McPherson et al. 2017; Bouchard et al. 2018). At least one malaria resistance gene has become less effective: Plasmodium vivax has recently evolved a novel red cell invasion mechanism allowing it to infect FY*O gene carriers via other red cell proteins in two African populations (Niang et al. 2018; see Phase IV). 2. Rising seas, mosquito- Insect populations are fostered by the expanding coastal brackish waters from rising seas borne infections (Ramasamy and Surendran 2016; Diem et al. 2017). In Sri Lanka, mosquito-borne dengue fever was linked to larval density in brackish waters (Ramasamy and Surendran 2012). 3. Dust from deforestation Ambient dust is associated with surges of infectious diseases. African and Asian dust can carry a high density of viable bacteria (Phase I). In the southwestern U.S., Valley fever is associated with dust storms that increased 2.4-fold since 1990 (Tong et al. 2017), while the African “meningitis belt” is strongly associated with seasonal surges of Saharan dust (Pérez García- Pando et al. 2014; Woringer et al. 2018). Saharan dust is seasonally transported to the Ca- ribbean and southeastern U.S. (Conway et al. 2019). 4. Migrations from drought Refugee camps are vulnerable to infections, fostered by antibiotic resistance, poor hygiene, and heat malnutrition, and limited medical services (Nellums et al. 2018; Schwartz and Morris 2018). African and Asian refugee camps are rife with cholera (Golicha et al. 2018) and respiratory viruses (Wu et al. 2019). Asylum seekers in Germany had severalfold more antibiotic resistance genes than native controls, including two genes absent from controls (Häsler et al. 2018). 5. Ozone and respiratory Ozone elevations are strongly associated with asthma. In the Central Valley of California, disease interquartile elevations of ozone increased emergency room visits for asthma in children (OR 1.22) and adults (OR 1.1) by 10% (Gharibi et al. 2018). Ozone levels also surge during heat events, with particular impact to urban inhabitants (Diem et al. 2017). Global warming will inevitably increase ozone because its chemical production responds linearly to temperature (Steiner et al. 2010), e.g., Los Angeles ozone levels varied daily by twofold across the ambient temperatures of 22 to 327C. 6. Mortality from heat stress Cities are “urban heat islands” with ambient temperatures above rural areas with more foliage and lower density traffic. Extreme temperatures are predicted to increase mortality from heat stress by up to twentyfold in Africa and the Middle East (Diem et al. 2017; Ahmadalipour and Moradkhani 2018), with lesser but still major increases of mortality predicted for temperate zones (Eisenman et al. 2016; McLean et al. 2018). Air conditioning (AC) needs will increase, with corresponding demand for electrical power from fossil fuels and increasing air pollution. AC for vulnerable populations is already insufficient, but building design and urban planning can partly ameliorate needs for AC (Lundgren-Kownacki et al. 2018). and cigarettes, while some genes such as toxins may play important roles in amelio- ApoE4 became deleterious as our environ- rating the effects of exposures today, includ- ments changed faster than our genetics (Fig- ing survival of some elderly lifetime cigarette ure 8). smokers.

Data from Dennis et al. 2017, Figure 2. We defined three clusters in the timing of HSD: 5.3–4.7 MYA (seven genes); 3.3–2.3 MYA (12 genes); and 1.9–0.3 MYA (39 genes). These duplicated genes did not show disruptive mutations that would block transcrip- tion or translation, but expression by cell type is not fully characterized.
