Species conservation via the Endangered Species Act is highly politicized, yet few data have been gathered to illustrate the relationship of political party affiliation to species conservation perspectives. We conducted a nationwide public opinion survey and found that Democrats value species conservation more highly than do Republicans, and that Democrats are also more strongly supportive of the Endangered Species Act. Republicans place higher value on property rights than do Democrats, but members of both parties value economic growth as highly as wildlife conservation. The results imply that the Democratic propensity to value species conservation reflects a biocentric perspective that does not bode well for practical conservation efforts. Species conservation will depend upon the success of academicians and progressive political leaders in educating students and members of all parties about the fundamental conflict between economic growth and wildlife conservation.

The Royal Society of London held a scientific meeting in September 2000 focusing on two theories of the origin of AIDS: one, that it occurred through “natural transfer” of immunodeficiency virus from monkeys or chimpanzees to humans; and the other, that it occurred through iatrogenic transfer via contaminated polio vaccines used in Africa in the late 1950s. This meeting was the culmination of years of public contention over the polio-vaccine theory. Several dimensions of the politics of science are revealed by analysis of this issue, including the power of scientific editors, the use of the mass media, decisions regarding selection of speakers and organization of the meeting, and epistemological assumptions made by participants.

Kennewick Man, an early Holocene (9,000 years old) skeleton found in Washington State in 1996, has been a lightening rod for political discussion. Due to his alleged Caucasoid features, Kennewick Man controversially called into question who first peopled the Americas. A projectile point lodged in his hip also catapulted him to celebrity status. Spared the quick (within ninety days after an inquiry) repatriation typically required under the 1990 federal Native American Graves Protection and Repatriation Act (NAGPRA), Kennewick Man was fully examined by a team of scientists chosen by the government who were forbidden to discuss their findings. Although the team concluded that Kennewick Man has cranial features associated with both Caucasoids and modern Native Americans, he is considered mainly to resemble modern Japanese Ainu, Polynesians, and Southeast Asians, as are other early Amerindian finds. Despite the resolution of early controversies, Kennewick Man continues as a symbol of the ideology of repatriation. In this article, I review the evidence for my belief that, taken to an extreme, the demand to bury aboriginal skeletons, not only in America but also around the world, poses a potentially serious impediment to scientific enquiry.

In 1998, the Sierra Club membership voted in a contentious referendum to refrain from including restriction of U.S. immigration as part of its official club population policy. Club proponents of immigration reduction had declared the problem was simply the environmental impact of greater numbers of people; however, they failed to distinguish themselves from groups with much broader immigration-reduction agendas, leaving themselves open to charges of racism. The club faction calling for the exclusion of immigration issues from the policy, on the other hand, failed to acknowledge the demographic reality of the contribution of immigration (30%) to the growth of the U.S. population. As a result, current club policy is not credible, as it calls for a reduction in the U.S. population but ignores immigration. The Sierra Club's complex organizational structure and open, democratic political process make it particularly vulnerable to internal conflict during periods of changing perspectives within the organization.

Arguably, no curve in the world increases indefinitely—certainly no growth curve of human society. The quest for sustainable use of the planet involves estimating levels of activity, particularly resource use, that can continue indefinitely. Since the biosphere is dynamic, this continuation is not a stagnant, steady-state situation but rather a mutualistic interactive relationship between human society and the planet's ecological life support system. Human technology, creativity, and ingenuity may modify natural laws, but cannot be used to repeal them. Attempts to maintain the recent exponential growth of the human population, affluence, and artifacts cannot continue forever, or probably even for another century. At best, quality of life will be diminished, and, at worst, a substantial loss of human life will occur if both ethical and ecological issues are not freely and openly discussed. Sustainability may be visionary and unattainable, but it does offer an opportunity to improve the quality of life for future generations of humans and the other life forms, an opportunity that is far greater than possible with present unsustainable practices.

Many treatments for infertility require the use of donated gametes or embryos. Arguments have been made that all parties involved (donors, recipients, and children) should have open access to information about one another. The present article reports a survey of attitudes of 77 donors and 327 recipients in the state of Western Australia. Donors and recipients endorsed a register of nonidentifying information, but were less keen on a register of identifying information. They believed that medical personnel should have access to such registers, and that donors and recipients (but not children) should have access to nonidentifying, but not identifying, information. Typically, the sort of information respondents wanted to access pertained to health status and physical characteristics. Overwhelmingly, both donors and recipients saw gamete and embryo donation as more like blood donation than like adoption.

This article argues that an evolutionary psychological perspective could be useful for developing second-generation models of rationality. The standard model of complete rationality is inadequate primarily on the grounds that it generates predictions inconsistent with empirical data. The model is extremely useful and should not, nor cannot, realistically be dismissed. It accurately predicts outcomes in markets and openly competitive situations. However, behavioral phenomena that the standard theory has trouble explaining—such as mass contribution to public goods, types of cooperation, and altruism—are usually treated as “anomalies.” These outcomes are too prevalent and important to be treated as such. I attempt to build upon Elinor Ostrom's proposal to generate new models of rationality, which recognize the use of heuristics, norms, and rules, and are able to better account for empirical findings. I argue that second-generation models would benefit from the acknowledgment of social roles—but more specifically, evolved social roles. Evolved social roles are intuitive bundles of norms, expectations, and social strategies that shape an individual's player type. If we extend rationality to incorporate underlying bio-psychological mechanisms, such as evolved social strategies and evolved social roles, then we gain an understanding of a wider array of decision-making processes and social phenomena.

The age of puberty in many populations has declined steeply over recent centuries and may be declining still. Consequently, today's children tend to experience the hormonal stresses of rapid development at younger ages than did their ancestors, around whose later, if not more gradual, maturation traditional behavioral expectations formed. Little has been made of this “rush to puberty” outside the life sciences. This article reviews its historical documentation, scholarly appreciation, epidemiological correlations, putative physiological and environmental explanations, sociological implications, and largely latent politics.

At the November 1998 general election, Michigan citizens were given the opportunity to vote on Proposal B, an initiative that would have legalized physician-assisted suicide (PAS). PAS initiatives also have been held in Washington State, California, Oregon, and Maine, with only Oregon's passing. We use exit poll data to analyze the vote on Proposal B. Attributes associated with social liberalism—Democratic Party identification, less frequent church attendance, more education, and greater household income—led to increased odds of a “yes” vote. Attributes associated with social conservatism—Republican Party identification and frequent church attendance—led to decreased odds of a “yes” vote. Similar to the abortion issue, PAS's supporters strongly value personal autonomy, whereas its opponents strongly value the sanctity of life. Voter alignments like those in Michigan will likely appear in other states with the initiative process if PAS reaches their ballots.

If the prescriptive “ought” is separated from the factual “is,” an intellectual analysis of the real world is by definition without normative value. The naturalistic fallacy thesis—maintaining that normative and descriptive spheres must remain separated—is often presented in a weak sense that seems reasonable. However, only in a strong sense—by strictly separating facts and values—are fallacy accusations supported. We claim that this naturalistic fallacy thesis is unsound and that normative statements instead should be based on rational understanding as found in the Darwinian and social sciences. The Cartesian compromise should be abandoned, since only naturalism can provide a cogent framework for better understanding and support ethics with a solid foundation. Many people nurture values based on tradition, whim, subgroup identification etc., and they demand respect for those values. However, we can demand respect for values only when they have a rational foundation. The common belief in the thesis of naturalistic fallacy is an anti-intellectual device that shields values from rational inquiry.

This paper integrates several different but mutually consistent evolutionary approaches to ethnicity: genetic similarity theory, social identity theory, individualism/collectivism, an evolved racial/ethnic human kinds module, and rational choice mechanisms relying on domain general cognitive mechanisms. These theories are consistent with each other, and together they illustrate the interplay of evolved cognitive and motivational systems with mechanisms of rational choice that are able to choose adaptive strategies in uncertain, novel environments.

Biomedical research is a success by any standard. It has led to treatments and preventive practices that have caused rates of death from the major killers—heart disease, cancer, and stroke—to decline steadily over the past few decades (National Center for Health Statistics, 2002: Table 30). Hundreds of new drugs have been approved over the past decade (U.S. Food and Drug Administration, 2002), and another 1000 potential drugs are under development (Pharmaceutical Research and Manufacturers of America, 2002). The past year alone has seen breakthroughs in understanding afflictions as diverse as sickle cell anemia, tuberculosis, breast cancer, Alzheimer's disease, depression, and substance abuse.

This article explores long-term issues and problems that have seriously undermined the U.S. Chemical Testing Program established by the Environmental Protection Agency (EPA) under the Toxic Substances Control Act. This program is meant to gather information needed to protect human health and the environment from damaging exposure to toxic chemicals. Despite seemingly broad and impressive authority under the statute, there are a number of inherent difficulties, as well as substantial political constraints, that impede comprehensive oversight of chemicals in U.S. commerce. The article discusses several approaches that EPA has adopted to overcome statutory and political limitations and increase chemical testing information. The most recent and promising of these efforts has involved international negotiations to harmonize testing approaches with OECD nations and to cooperate on an agenda that will better share the testing burden on an international level.

In the past quarter century, the concept of culture has undergone change as evolutionary scientists have come to include social behavior in their purview. Evolutionary psychology is the newest field to concern itself with culture by claiming that most specific human behaviors are generated by minds specifically designed for these behaviors—and not from a general-purpose mind—as a result of adaptations made during the Pleistocene. Thus, mental behaviors are explained as having formed independently of cultural learning. In defending the concept, however, the leading proponents practically slough off culture as significant in human affairs. I argue that they have neglected the powerful explanatory statement of Darwin regarding at least one general-purpose adaptation of social animals, namely, the instinct for sociability, a position supported by recent neurological studies. Expanding the Darwinian concept, modern research shows that (1) the human brain was selected for sociability, which explains the origin and strength of culture, as well as its variability; (2) the development of complex culture in a pre-human primate initiated the two-and-one-half million-year evolution to modern humans; and (3) there are political contributions to cultural evolution that rest on the nature of groups (competitive and cooperative).

Twenty-five years ago, in November 1976, a physician misunderstood a cassette-tape providing continuing education for family practitioners to say that the rare neurological complication called Guillain-Barré syndrome could be a side effect of flu vaccines. When a recently vaccinated patient developed the syndrome, the physician alerted public officials and thereby started the process that ultimately ended the government campaign to immunize all Americans against swine flu. The physician was right, but for the wrong reasons, as Neustadt and Fineberg point out in the introduction to the 1983 edition of their classic case study of the swine flu episode (1983:xxv).

The present discussion of sociobiological approaches to ethnic nepotism takes Pierre van den Berghe's theory as a starting point. Two points, which have not been addressed in former analyses, are considered to be of particular importance. It is argued that the behavioral mechanism of ethnic nepotism—as understood by van den Berghe—cannot explain ethnic boundaries and attitudes. In addition, I show that van den Berghe's central premise concerning ethnic nepotism is in contradiction to Hamilton's formula, the essential principle of kin selection theory. It is further discussed how other approaches that make reference to ethnic nepotism are related to van den Berghe's account and its problems. I conclude with remarks on the evolutionary explanation of ethnic phenomena.

Standard of living is determined in part by the availability of ecological resources, and in part by the availability of “cheap energy.” The demise of cheap energy is likely to occur during the twenty-first century. Gradually, over this time, humans will be restricted to using renewable natural capital. Reliance on renewable energy sources will require a reduction in population to within the range of 1.5 to 3 billion people in order to maintain what most of us would regard as an adequate lifestyle. Attention is drawn to the need for nations to exercise sovereign responsibility.
