Abstract

Despite advances in fields like genetics, evolutionary psychology, and human behavior and evolution — which generally focus on individual or small group behavior from a biological perspective — evolutionary biology has made little impact on studies of political change and social history. Theories of natural selection often seem inapplicable to human history because our social behavior is embedded in language (which makes possible the concepts of time and social identity on which what we call “history” depends). Peter Coming's Holistic Darwinism reconceptualizes evolutionary biology, making it possible to go beyond the barriers separating the social and natural sciences. Corning focuses on two primary processes: “synergy” (complex multivariate interactions at multiple levels between a species and its environment) and “cybernetics” (the information systems permitting communication between individuals and groups over time). Combining this frame of reference with inclusive fitness theory, it is possible to answer the most important (and puzzling) question in human history: How did a species that lived for millennia in hunter-gatherer bands form centralized states governing large populations of non-kin (including multi-ethnic empires as well as modern nation-states)? The fragility and contemporary ethnic violence in Kenya and the Congo should suffice as evidence that these issues need to be taken seriously. To explain the rise and fall of states as well as changes in human laws and customs — the core of historical research — it is essential to show how the provision of collective goods can overcome the challenge of self-interest and free-riding in some instances, yet fail to do so in others. To this end, it is now possible to consider how a state providing public goods can — under circumstances that often include effective leadership — contribute to enhanced inclusive fitness of virtually all its members. Because social behavior needs to adapt to ecology, but ecological systems are constantly transformed by human technology and social behavior, multilevel evolutionary processes can explain two central features of human history: the rise, transformations, and ultimate fall of centralized governments (the “stuff” of history); and the biological uniqueness of Homo sapiens as the mammalian species that colonized — and became top carnivore — in virtually every habitable environment on the earth's surface. Once scholars admit the necessity of linking processes of natural selection with human transformations of the natural world, it will seem anomalous that it has taken so long to integrate Darwinian biology and the social sciences.

23.What anthropologists call “stateless societies” are cultures without a state with complex relations between kin-groups. A good example is a culture called the Ifugao in the Philippines, which provides an example of the modern survival of a “stateless society” that has retained many of the attributes of its traditions. In this culture, an isolated individual seems exceedingly rare because members of the community are embedded in a kin-group and its rituals/culture/identity: “Each sibling group is the center of an exogamous, bilateral kindred, which is reckoned vertically to great-great-grandparents and laterally to third cousins…. Government institutions are poorly developed among the Ifugao, and chiefs, councils, and politically defined districts or other units are lacking in the traditional culture. ‘The functions of government are (or were) accomplished by the operation of collective kinship obligations, including the threat of blood feud, together with common understanding of the adat or custom law given the people by ancestor heroes, in particular the inviolability of personal and property rights.’ … Informal arbitrators (monbaga), who are ‘respected men of wealth skilled in knowledge of genealogy and adat,’ and whose decisions can be backed up by a large and powerful kin group, serve as go-betweens who ‘negotiate and witness property dealings, marriage transactions and the like, and who are paid for their services’ (LeBar 1975: 81). A very loose type of community leadership has traditionally been achieved, however, through the role of the ‘rice chief,’ one of the leading priests of the area, to whom members of the community give voluntary obeisance. The principal function of the “rice chief” was merely to determine on which days certain religious customs of common interest to all should be observed.” EthnoAtlas.

Focusing on distinctive genes among the invading Anglo-Saxons, “Y chromosome studies show that they contributed up to 70% of the modern English gene pool.” Computer models of Mark Thomas and colleagues cited in this note show that: “For example, even if the invaders were only 5% of the population, their Y chromosomes would reach the 50% mark within 15 generations if they were 1.4 times as likely as the locals to reproduce and the intermarriage rate was 7%.” While dominance can explain higher reproductive rate, the lower intermarriage rate seems impossible to explain without linguistic markers of the in-group and out-group.Google Scholar

27.Dalton, Rex, “Decoding our cousins,” Nature, 20 July 2006, 442:238–240. If successful, the project to decode the Neanderthal genome, described in Dalton's report, may well lead to more precise dating of the origins of linguistic evolution among hominids. Since Neanderthal fossil assemblages provide evidence of tool-making and use (e.g., the “spear points, hand axes, scrapers and animal bones” found at the site near Jonzac, France) and a researcher has claimed there's evidence of cannibalism at the Moula-Gercy cave (ibid., citing Alban Defleur, Science, 1999, 286:128–131), the latest research already confirms that Neanderthals were an intermediate step in the progression of both social cooperation and competition from non-human primates to contemporary humans.Google Scholar
28.The principal point is probably not the precise date of linguistic communication, but the emergence of humming and tonal (or “musical”) modifications of the nonhuman primate signals, permitting local variations in signals which could then evolve into naming and grammatically structured speech. SeeMithen, Steven, The Singing Neanderthals: The Origins of Music, Language, Mind and Body (Cambridge, MA: Harvard University Press, 2007). The link between music and language is relevant because it should remind us of the central role of singing in social identity — as epitomized by the powerful emotional responses of solidarity and reassurance elicited by a national anthem like “La Marseillaise” in France, “God Save the King” in England, or the “Star Spangled Banner” in the U.S.Google Scholar

38.In particular, since the presence of a martyr in a family increases the kin-group's status, mating opportunities of the martyrs' collateral relatives may well be enhanced. Whereas it is rare that humans consciously calculate long-term reproductive success (and there is no evidence of such calculations on the part of suicide bombers in Iraq), such behaviors are typically fostered by traditional practices that elicit positive emotional responses. For example, a rare case of an Islamic woman who was apprehended before her planned suicide bombing could be carried out provides confirmation: When asked why she had volunteered for a deed not normally committed by Islamic women, the captured terrorist explained that an American soldier had put his boot on her husband's face when interrogating him; since this action brings severe shame on the family of the victim of a cultural outrage, she felt martyrdom in killing infidels was essential to restore her family's honor. Whereas ancient philosophers include thymos and honor among the powerful motives for human behavior (e.g., Plato and Aristotle), contemporary rational choice theorists who ignore such intangible motives cannot appreciate their effects on the kin-group's long-term reproductive success.Google Scholar
39.E.g., Exod. 19:3–8; 34:10–28 (King James Version). Note especially the divine promise to “cast out the nations before thee, and enlarge thy borders: neither shall any man desire thy land, when thou salt go up to appear before the Lord thy God thrice in the year.” (Exod. 34: 24). Moreover, the punishment for disobeying the divine commandments will be pestilence, destruction, and exile (Lev. 26:14–48): e.g., “And I will make your cities waste, and bring your sanctuaries unto desolation … And I will scatter you among the heathen, and will draw out a sword after you: and your land shall be desolate, and your cities waste” (Ibid 26:31, 33). Conversely, the reward for obeying “all the ways which the Lord your God hath commanded you [will be] that ye may live, and that it may be well with you and that ye may prolong your days in the land which ye shall possess” (Deut. 5:33). Unlike the New Testament, but comparable to many other religions throughout the world, the rewards of belief are this worldly and linked to protection against outside enemies of a named society and population. Indeed, the occupation of the “promised Land” is based on an explicit command that the Hebrews take Canaan by force with the promise of divine assistance conditional on showing no mercy to the defeated inhabitants: “When the Lord thy God shall bring thee into the land whither thou goest to possess it, and hath cast out many nations before thee … And when the Lord thy God shall deliver them before thee; thou shalt smite them, and utterly destroy them; thou shalt make no covenant with them, nor shew mercy unto them” (Deut. 7:1–2). The Koran presents a similar relationship between obedience to divine commandments and the promise of military protection as long as rival peoples are “annihilated” when they fail to adopt Islamic law (e.g., for “annihilation” of the Jews who do not accept Islam, seeKoran, , Surah 17).Google Scholar
40.The Ten Commandments (Exod. 20:2:17) are followed by the comprehensive laws articulated in the remainder of the books of Exodus, Leviticus, and Deuteronomy. Many of these laws promote increased reproductive success either by providing assurances that parental investment will not be lost due to the sexual behavior of others or by directly encouraging r-selected reproductive behavior. Precisely because these laws are available in the nearest copy of the Bible yet rarely considered in the light of contemporary evolutionary theory, detailed analysis follows.Google Scholar

For the latest work, focused on the roles of emotion and cognition in decision-making, see notes 1 through 7 below. It is worth adding that the disjunction between long-term effects on reproductive success (the objective measure of costs and benefits in evolutionary theory) and these neuroscientific studies of cognition poses a more serious challenge to “rational choice” models than outlined above. Inclusive fitness (a concept only recently developed and still little known by social scientists) is quite obviously not consciously salient in normal cognitive assessments, but established emotional responses and traditional legal norms are often shaped by natural selection. As a result, future social scientists might replace models of “rational choice” with models focused on “emotional choice” if such a theoretical change didn't threaten to undermine the perceived economic benefits of higher education in our students.Google Scholar

58.Note that this model of a hunter-gatherer band or other small social group assumes there are dominant individuals in the group whose actions are known before their followers' decisions are made. Olson's “logical” model (above, note 7) ignores facts like this even they are ubiquitous in human social life. While a collection of individuals of roughly equal status who are unknown to each other often approximates the purchasers in the competitive markets of a large industrialized society, it is unrealistic to apply the sociological assumptions of such “rational choice” models to the political decisions of most actual human societies.Google Scholar
59.In Table 2, this is the equivalent of some players perceiving the cost of non-provision of the collective good as minimal (say 25 units instead of 9000 units). In this case, should both players contribute, the public good has a net benefit for each of −50 units (the cost of 75 is only reduced by a benefit of 25). Since each individual will lose 75 units if others don't contribute and the benefit is so much less than the individual contribution, there will be an overwhelming temptation to construct rationalizations confirming the limited utility of the proposed expense. In the modern state (Table 3), an example is provided by some expensive military technologies, such as the anti-missile missile, whose value as a collective good was strongly attacked.Google Scholar

The 27 members of the student body form a close community engaged in an intense educational project delineated by what Deep Springs' founder, L. L.

The principle underlying the three pillars is that manual labor and political deliberation are necessary supplements to the liberal arts in the training of future servants to humanity.

65.Zimbabwe (the former Rhodesia) had highly productive farms that were owned by whites and produced a surplus for export; the crucial practice has been the forcible seizure and redistributing of these farmlands to President Mugabe's political allies (with devastating effects on output).

And if it will make no peace with thee, but will make war against thee, then thou shalt besiege it: And when the Lord thy God hath delivered it into thine hands, thou shalt smite every male thereof with the edge of the sword: But the women, and the little ones, and the cattle, and all that is in the city, even all the spoil thereof, shalt thou take unto thyself; and thou shalt eat the spoil of thine enemies, which the Lord thy God hath given thee.” (Deut., 20: 10, 12–14).Google Scholar

(Cheltonham: Edward Elgar, 2004), pp. 166–183. Although early civilizations in the Amazon may seem to be an exception, their agricultural productivity was a complex adaptation to an environment ill-suited to agriculture. The poverty of Amazonian soils and resulting need to base agriculture on planting crop trees whose leaves shelter the soil from the physical effects of heavy rains explain why the introduction of the steel axe by European explorers had such devastating the ecological consequences.

Apart from hyperinflation (1,000% in 2006), the most telling statistics are average life expectancies of 37 years for men and 34 years for women (in a country with rates of education that are higher than other African societies).

70.Having taught ancient and modern political philosophy in the Ivy League since 1961 and translated as well as analyzed the works of Rousseau (whose concept of the “general will” focuses on the need to make manifest support for collective goods), my response could be attributed to a professional specialization in the study of justice and morality in civilized societies. Even so, scenes like those just described were unheard of fifty years ago. As every thinking adult is well aware, the behavioral standards of our society have been radically transformed since our victory in World War II and the Cold War.Google Scholar

72.Rousseau's fame began with the publication of his prize-winning First Discourse, written in response to the essay contest of 1749 in which the Academy of Dijon asked “Has the restoration of the sciences and arts tended to purify morals” and Jean Jacques replied with a resounding negative: “When there is no effect, there is no cause to seek. But here the effect is certain, the depravity real, and our souls have been corrupted in proportion to the advancement of our Sciences and Arts to perfection. Can it be said that this is a misfortune particular to our age? No, Gentlemen; the evils caused by our vain curiosity are as old as the world. The daily ebb and flow of the Ocean's waters have not been more steadily subject to the course of the Star which gives us light during the night than has the fate of morals and integrity been subject to the advancement of the Sciences and Arts. Virtue has fled as their light dawned on our horizon, and the same phenomenon has been observed in all times and in all places.”Rousseau, Jean Jacques, “Discourse on the sciences and arts,” in Masters, Roger D. and Kelly, Christopher, eds., Collected Writings of Rousseau, vol. 2 (Hanover, N.H.: University Press of New England, 1992), p. 7.Google Scholar

The wording of another passage on this page has persuaded me that Strauss himself realized that a more comprehensive understanding of recent scientific research on human nature would be absolutely essential for the survival of philosophy: “The fundamental dilemma, in whose grip we are, is caused by the victory of modern natural science. An adequate solution to the problem of natural right cannot be found before this basic problem has been solved.”Google Scholar
