This finding is based on a sample of approximately 50 million cases using common, readily available demographic data, e.g., state of birth, birth date, death date, and gender. Physicists Nair, Geim et al. had found precisely the same fractional difference, 0.023, in the absorption of white light (sunlight) by a single-atom thick layer of graphene, a carbon skeleton resembling chicken wire fencing. This absorption fraction, when divided by P, yielded the FSC and was the first time this constant could ‘‘so directly be assessed practically by the naked eye”. As the GR is a reflection of sexual differentiation, this paper reveals that a quantum mechanical process, as manifested by the FSC, is playing a role in the primordial process of replication, a necessary requirement of life. Successful replication is the primary engine driving evolution, which at a biochemical level, is a quantum mechanical process dependent upon photonic energy from the Sun. We propose that a quantum-mechanical, photon-driven chemical evolution preceded natural selection in biology and the mechanisms of mitosis and meiosis are manifestations of this chemical evolution in ancient seas over 3 billion years ago. Evolutionary processes became extant first in self-replicating molecules forced to adapt to high energy photons, mostly likely in the ultraviolet spectrum. These events led to evolution by natural selection as complex mixing of genetic material within species creating the variety needed to match changing environments reflecting the same process initiated at the dawn of life. Both evolutionary mechanisms coexist and are interactive. The periodic energy of solar maxima is likely modulating the human genome from maternal integument to an embryo in utero with non-local mechanisms intrinsic to quantum mechanics. Ó 2009 Elsevier Ltd.

Introduction This paper will show that readily available demographic data, e.g., birth date, death date and gender, can reveal that quantum mechanical processes modulate the human gender ratio, (Nmale/ Nmale + Nfemale). Sunlight is crucial to life beginning 3.5 billion years ago not only for its energy, but also for the evolutionary changes forced upon the biosphere due to variation in light. Early life had to devise an efficient method of collecting solar energy and to protect itself against damaging photons, like ultraviolet radiation (UVR); it also had to cope with variation in that energy. Because of these stresses, life has developed several ingenious ways of rearranging genetic material to increase survivability through increased adaptability.

The development of mitosis, parthenogenesis, semi-meiosis (the first stage of meiosis), then the second stage of meiosis leading to sexual selection, and combinations of these mechanisms have been important in bringing forth a myriad of organisms to match environmental niches over the eons [1–4]. Darwin’s ‘‘forms most beautiful and most wondrous” was the result. Although sexual selection might not have been the main mechanism in producing multiple orders such as occurred in the Cambrian, it has allowed life forms to adapt to increasingly specific environments [1]. The human species employs the full meiotic process through sexual differentiation with the potential along with epigenetic modifications, to create an infinite variety of phenotypes. The human gender ratio is a metric that reflects this sexual differentiation. Here we present evidence that the human gender ratio at death (GRat death) still reveals an intimate relationship between solar photons and the electrons in our chromatin/nucleosomes as manifested by the fine structure constant (FSC) of quantum mechanics. G.E. Davis Jr., W.E. Lowell / Medical Hypotheses 73 (2009) 296–301 We read a paper by physicists Nair, Geim and colleagues regarding the calculation of the FSC in quantum mechanics by measuring white light (sunlight) absorption through a single layer of graphene, a form of graphite with a carbon skeleton resembling chicken wire fencing [5,6]. Absorption was 2.3%, an incredible amount given that this two-dimensional gossamer of graphene was only a single atom in thickness. According to quantum mechanical calculations, this percentage, expressed as a fractional change (e.g., 0.023) divided by P, yields a fair approximation of the FSC, also called alpha, which is equal to 0.00729735. . .. or 1/137. We noted that the 2.3% absorption by graphene matched, within 0.1%, our findings of the fractional difference in the human GRat death between those conceived (and likely born) in peak solar cycle years as compared to those conceived in non-peak years [7]. If macroscopic, albeit extremely thin, carbon reveals a fundamental quantum mechanical constant, is it possible that the carbon skeleton in our DNA or chromatin is performing the same feat? We set out to answer this question by gaining access to a large database of death records from the entire United States. Gender ratio The gender ratio (GR), defined as (Nmale/Nmale + Nfemale) is a rarely used metric in medical reports. The GR can refer to this ratio at birth, which favors males, or at death which favors females, as the latter live between 2 and 10 years longer (average in USA is 7 years) depending upon social resources and environmental hazards. GRat death is an indicator of lifestyle differences as well as the susceptibility to genetic and epigenetic diseases which manifest themselves over a lifetime. The GRat birth is reflective of gender bias at conception, favoring males in the human species, and lethal genetic mutation or environmental stressors in utero [8]. Reports show that the GRat birth is greater at lower latitude; they also reveal that birth in certain seasons may disadvantage males [9–12]. It is not clear whether temperature or decreased variation in light determine these phenomena [13–15]. Increasing solar intensity, especially over the past century, is possibly also a factor in decreasing the GRat birth [16]. However, the GR can be a sensitive indicator of environmental conditions, especially in animals like reptiles [17]. Temperature is a reflection of ambient infrared radiation, but other wavelengths of light have profound biological effects, especially ultraviolet radiation (UVR) [18,19]. Our research has concentrated on the variation in radiation due to 11-year solar cycles and the relationship between the human GRat death and the peaks of solar cycles [7]. We found that in the state of Maine there is a 2.2% increase in GR from birth to death and a 2.4% increase in GRat death from non-peak solar years to peak years, averaging 2.3% between the two measurements and we were puzzled by this. Because of known variation in environments and regional mores, we thought it necessary to recalculate GR in a larger population over a wide geographic area using data from other states [20,21]. Solar cycles Our Sun is a variable star [22]. It cycles in its energy output on average every 11 years, with a range from 8 to 14 years. During the peaks of these cycles, which occur over about 3 years, solar storms increase in number and strength proportionate to the number of sunspots as measured by astronomers for many centuries and meticulously recorded since the mid-18th century. During solar peaks, photonic energy increases by 0.1% overall, but the UVR moiety increases disproportionately up to 19% of total solar insolation during these approximately 3-year periods [23]. Photons of UVR are more energetic than photons of visible light and one would 297 expect that an increase in these photons would affect life. Previous research has shown that 308 nm (UV-B) light has the most biological effect on DNA [24]. Not until the year 1984 did we have evidence that sunlight had an effect on the human central nervous system in its role in seasonal affective disorder [25]. Subsequently, many investigators have reported effects related to solar cycle and seasonal changes in light on the incidence of human disease [26,27]. We recently reported that solar peaks affect human longevity and several human diseases, particularly mental illness [28,29]. We, and others, hypothesized that UVR was the likely wavelength of radiation responsible for altering the genome [24]. The non-peak years of solar cycles have been associated with an increase in birth defects and cancer, probably because during these solar minima the magnetosphere is weaker thus allowing increased atmospheric penetration of cosmic rays (high-energy neutrons and protons) which are capable of damaging DNA through point mutations [30–33]. Major mental illnesses have a higher incidence in those conceived/born during solar maxima, and since these maladies are usually polygenic, they are more likely to be epigenetic in nature. We recently found that persons conceived/ born during these maxima had an average 1.5 year decrease in lifespan suggesting that modifications in the genome, especially the epigenome, result in enough variety to produce disease that shortens life by about 3% [34]. Alpha, the fine structure constant The FSC is derived from quantum theory and first described by physicist Arnold Sommerfeld in 1916. It has several physical interpretations in quantum mechanics depending upon context. While a detailed explanation is beyond the scope of this article, the FSC essentially relates the strength of the interaction of photons (energy) to relativistic electrons (matter). The most recent value for this dimensionless constant FSC is 1/137.035999084 (51), with an uncertainty twenty times smaller than for any previous independent determination [35]. Slight deviation from the numerical value of this constant can result in a universe totally unlike the one in which we exist [36]. Its numerical value was a mystery to Nobel physicists P.A.M. Dirac, a founder of quantum mechanics, and Richard P. Feynman, one of the creators of quantum chromodynamics. The FSC appears recurrently in many applications and is one of the fundamental constants of nature [37,38]. Outside of the world of cyclotrons and other exotic devices in physicists’ laboratories, no one expected to be able to derive the FSC from macroscopic material. This was recently accomplished by Geim and colleagues as mentioned above. In this article we show that the FSC can also be derived from simple demographic data. Methodology Death data Data were obtained from the National Center for Health Statistics (NCHS) for deaths in all 50 states and the District of Columbia from 1979 to 2005, a total of 58,733,243 death records. Data used in this study included sex, state of birth, date of birth (month and year), date of death (month and year), and race. This study reports the GR by state of birth and sex for White only race category (N = 50,778,214). The race category White included individuals of Hispanic race, since data on Hispanic Origin was not recorded from 1979 to 1988 these represented approximately 6% of the sample. Birth dates ranged from 1854 to 2005; however, birth dates prior to 1870 were not used (N = 392) since they antedate the first solar cycle used in the analysis. Sex data for the total sample is displayed in Table 1. 298 G.E. Davis Jr., W.E. Lowell / Medical Hypotheses 73 (2009) 296–301 Table 1 Gender table for White onlya.

Solar data The average number of annual sunspots per year was also collected from the NOAA Web site and the three peak years (of sunspots) of each of the past 12 cycles was obtained. The average annual sunspot number for the past 250 years was found to be 49; for the past 60 years the average is 107.5; for the most powerful cycles (sunspots > 135), the average is 154, about three times the 250-year average. Methodology Birth year data were grouped by solar maximum or solar minimum defined as follows: the three highest sunspot years to include the peak year and/or the year before or the year after were defined as the Maximum Solar Period (MAX); the years before and after each 3 year MAX cycle were grouped as Minimum Solar Period (MIN). Solar cycles used in the study ranged from 1870 to 2005. These data are displayed in Table 2. The gender ratio (GR) was determined using 2X2 table for MAX MIN group and sex for each state (see Table 3 for an example table for the state of Florida where GRpeak = 0.5582 and GRnon-pk = 0.5479). Chi Square analysis was calculated for each state, respectively, using SAS software (version 9.1, SAS Institute, Cary, NC). Data are summarized in Tables 4 and 5; all states have a P-value < 0.0001.

The states of Arizona, Alaska and Nevada, which have experienced large immigrations over the past half-century, were not used in the analysis because there were insufficient native-born for the GRat death to reach statistical significance.

We hypothesize that a quantum mechanical process (QMP) is in some way involved in modulating the GR as it relates to greater insolation during solar cycle peaks. In addition, if GR is affected by a QMP, then one must consider that RNA, the probable initial replicating molecule in the primordial ‘‘organic soup” was also created by a QMP, and from that initiation, the innate complexities of biological enzymes, proteins and genome replication were also driven by a QMP [39,40]. According to a recently published paper, even a complex molecule like RNA has the potential of self-sustained replication with a doubling time of approximately one hour; although a QMP was not specifically addressed, it is likely that such complexity could be accomplished only through the multiple pathways of a QMP [41]. The notion that multiple complex chemical pathways could occur over a short period of time has been based upon the multiple universe concept first put into mathematical form by Everett in 1957 and embraced by others since [42–44]. A study of photosynthesis gives a concrete example of a QMP in action through the technique of two-dimensional electronic spectroscopy first developed at the University of California at Berkeley. There, and at the Lawrence Berkeley National Laboratory, Fleming, Engel and colleagues showed that photosynthesis linking photons to matter is nearly 100% efficient due to a quantum coherence phase that was surprisingly long in duration, a 660 femtoseconds (660 10 15 s) [45]. According to Graham, a wavelike behavior during that time span ‘‘enabled the system to simultaneously sample all the potential energy pathways and choose the most efficient one”. Similar events, though not fully worked out in humans, possibly occur in human chromosomes at conception where, at the union of X–X or X–Y chromosomes, a process of X-inactivation takes place [46]. This inactivation is necessary to equalize the dosage of X alleles with respect to males, which have a single X [47]. What determines whether the male or female allele in an X–X pairing will prevail is enigmatic, but it may also be a QMP which ‘‘selects” the allele that works the most efficiently in ensuring survival. A similar argument is made for the evolutionary optimization of enzymes [48]. However, the single X-allele in an X–Y pairing puts males at risk for disease if there are any deficient X-alleles. We have previously reported that males will have 28% more disease on average than females, thereby shortening male lifespan by 7 years [34,49]. How might the complicated structure of DNA, entwined in its tertiary conformation as chromatin, absorb photonic energy in the same amount as does the simple carbon skeleton of graphene? We refer the reader to a website which cleverly shows an animated image of chromosome composition [50]. The chromosome is composed of DNA spooled about histone protein cores, forming beads called nucleosomes. Chromatin is the combination of DNA and these histone proteins. The purpose of this complicated conformation may not only be to compact an extremely long DNA strand into a small space in the cell nucleus, but it may also conceivably form a structure that maximizes photon absorption while minimizing the formation of damaging free radicals, similar to what oc- [A B]/B [A B]/BP curs in photosynthesis. There is recent evidence that the conformation of RNA or DNA affects how energy is dissipated in UVR-induced excited states [51]. One wonders how light can affect an embryo in a uterus patently shielded from light. There can be no doubt from the results of many studies that environmental events in fetal development predispose to various disorders in adult life [34,52]. There is, as previously referenced, considerable evidence that photons can engender disease processes by making epigenetic/genetic alterations in the genome which is especially vulnerable at conception and early gestation. Known mechanisms include hormones like vitamin D made by UVR in the skin, and melatonin, whose concentration is affected by ambient light and which modulates wakefulness. Chemokines, cytokines, and neurotransmitters like serotonin, which affects mood in seasonal affective disorder or depression, are also proven mechanisms of the action of light at a cellular level. However, quantum mechanisms are ‘‘non-local” in that they work without direct contact or apparent connection with the affected tissue. This reality of ‘‘action at a distance” was proven by physicist John S. Bell in 1964 with his non-equality theorem, and in essence all reality on a quantum level is non-local [53,54]. But there is also increasing evidence that quantum mechanical events have macroscopic manifestations in crystals, ferromagnets and superconductors [55]. Although it is likely that a QMP is ongoing in the human soma, evidence similar to that which was recently discovered in photosynthesis is still in development. Conclusions The gender ratio at peaks and non-peaks of solar cycles reveals the FSC. The likelihood of this unusual constant appearing by chance alone is negligible, but a large database of 50 million death records was required to have the statistical power to discover it. A QMP modulates the human GR using the difference in photonic energy between solar cycle peak years and non-peak years. We hypothesize that X-inactivation is also a QMP. Because the QMP-modulated GR is the result of sexual selection (natural selection), and because sexual selection is a meiotic process that evolved from mitosis, then it is likely that the primordial replication of molecules (probably RNA) was also a QMP. There must be at least two types of evolution in Earth’s history: (a) A molecular evolution (3.5 billion years ago), produced by the waxing and waning of solar energy that perturbs genetic material on average at least (3 years/11 years = 0.28) 28% of the time. (b) A more recent evolutionary process (<2.5 billion years ago), utilizing meiosis and Darwinian natural selection to match the variety imposed by an ever-changing environment. This study is evidence of another macroscopic manifestation of quantum mechanics. 300 G.E. Davis Jr., W.E. Lowell / Medical Hypotheses 73 (2009) 296–301 Study strengths Because of a large N the study has great statistical power. Nevertheless, three states (Alaska, Arizona and Nevada) were excluded for this analysis because relatively few persons were born in those states; the difference in GR from MAX to MIN was not statistically significant. The study had a range of latitudes and elevations across the USA that created variation, yet the mean and median of FSC calculation values converged. Study weaknesses The study examined the White race category to avoid having race as a possible confounding effect; however, this category included cases that were of Hispanic origin. Other races will be analyzed in the future. How this study contributes to new knowledge This work also presents a macroscopic manifestation of quantum mechanics in the biological world, in this case, the human gender ratio. This study proposes a quantum theory of evolution from the onset of life in the ‘‘primordial soup” to the combinations of reproductive strategies that have subsequently developed. Future work We would like other researchers with backgrounds in quantum mechanics, genetics, statistics, biochemistry and molecular biology, among other disciplines, to replicate our findings and to explain how chromatin (or DNA) absorbs the same fraction of photon energy between peaks and non-peaks of solar cycles as a two-dimensional layer of graphene absorbs from white light.
