Making Sense of Evolution explores contemporary evolutionary biology, focusing on the elements of theories—selection, adaptation, and species—that are complex and open to multiple possible interpretations, many of which are incompatible with one another and with other accepted practices in the discipline. Particular experimental methods, for example, may demand one understanding of “selection,” while the application of the same concept to another area of evolutionary biology could necessitate a very different definition.

Biological research on race has often been seen as motivated by or lending credence to underlying racist attitudes; in part for this reason, recently philosophers and biologists have gone through great pains to essentially deny the existence of biological human races. We argue that human races, in the biological sense of local populations adapted to particular environments, do in fact exist; such races are best understood through the common ecological concept of ecotypes. However, human ecotypic races do not in general (...) correspond with 'folk' racial categories, largely because many similar ecotypes have multiple independent origins. Consequently, while human natural races exist, they have little or nothing in common with 'folk' races. (shrink)

Twenty years have passed since Gould and Lewontin published their critique of ‘the adaptationist program’ – the tendency of some evolutionary biologists to assume, rather than demonstrate, the operation of natural selection. After the ‘Spandrels paper’, evolutionists were more careful about producing just-so stories based on selection, and paid more attention to a panoply of other processes. Then came reactions against the excesses of the anti-adaptationist movement, which ranged from a complete dismissal of Gould and Lewontin’s contribution to a positive (...) call to overcome the problems. We now have an excellent opportunity for finally affirming a more balanced and pluralistic approach to the study of evolutionary biology. (shrink)

This letter addresses the editorial decision to publish the article, “Research on group differences in intelligence: A defense of free inquiry” (Cofnas, 2020). Our letter points out several critical problems with Cofnas's article, which we believe should have either disqualified the manuscript upon submission or been addressed during the review process and resulted in substantial revisions.

Lewis et al. (2011) attempted to restore the reputation of Samuel George Morton, a 19th century physician who reported on the skull sizes of different folk-races. Whereas Gould (1978) claimed that Morton’s conclusions were invalid because they reflected unconscious bias, Lewis et al. alleged that Morton’s findings were, in fact, supported, and Gould’s analysis biased. We take strong exception to Lewis et al.’s thesis that Morton was “right.” We maintain that Gould was right to reject Morton’s analysis as inappropriate and (...) misleading, but wrong to believe that a more appropriate analysis was available. Lewis et al. fail to recognize that there is, given the dataset available, no appropriate way to answer any of the plausibly interesting questions about the “populations” in question (which in many cases are not populations in any biologically meaningful sense). We challenge the premise shared by both Gould and Lewis et al. that Morton’s confused data can be used to draw any meaningful conclusions. This, we argue, reveals the importance of properly focusing on the questions asked, rather than more narrowly on the data gathered. (shrink)

The concepts of adaptive/fitness landscapes and adaptive peaks are a central part of much of contemporary evolutionary biology; the concepts are introduced in introductory texts, developed in more detail in graduate-level treatments, and are used extensively in papers published in the major journals in the field. The appeal of visualizing the process of evolution in terms of the movement of populations on such landscapes is very strong; as one becomes familiar with the metaphor, one often develops the feeling that it (...) is possible to gain deep insights into evolution by thinking about the movement of populations on landscapes consisting of adaptive valleys and peaks. But, since Wright first introduced the metaphor in 1932, the metaphor has been the subject of persistent confusion, from equivocation over just what the features of the landscape are meant to represent to how we ought to expect the landscapes to look. Recent advances—conceptual, empirical, and computational—have pointed towards the inadequacy and indeed incoherence of the landscapes as usually pictured. I argue that attempts to reform the metaphor are misguided; it is time to give up the pictorial metaphor of the landscape entirely and rely instead on the results of formal modeling, however difficult such results are to understand in ‘intuitive’ terms.

Phylogenetic information is often necessary to distinguish between evolutionary scenarios. Recently, some prominent proponents of evolutionary psychology have acknowledged this, and have claimed that such evidence has in fact been brought to bear on adaptive hypotheses involving complex human psychological traits. Were this possible, it would be a valuable source of evidence regarding hypothesized adaptive traits in humans. However, the structure of the Hominidae family makes this difficult or impossible. For many traits of interest, the closest extant relatives to the (...) human species are too phenotypically different from humans for such methods to provide meaningful data. While phylogenetic information can be useful for testing adaptive hypotheses in humans, these generally involve traits that are (a) not widely shared in the species or (b) fairly widely shared in the Hominidae family, and hence likely of a lower order of complexity than the sorts of traits evolutionary psychology has so far been interested in.

The renewed interest in the issue of black reparations, both in the public sphere and among scholars, is a welcome development because the racial injustices of the past continue to shape American society by disadvantaging African Americans in a variety of ways. Attention to the past and how it has shaped present-day inequality seems essential both to understanding our predicament and to justifying policies that would address and undermine racial inequality. Given this, any argument for policies designed to pursue racial (...) justice must be, at least in part, backward-looking, justifi ed partly as compensation for the effects of the wrongs of the past. However, some arguments about black reparations, both pro and con, are focused too far in the past. An unspoken assumption of much of the debate about black reparations is that these would be reparations for slavery. This, we argue, is a mistake. Racial inequality in the United States today may, ultimately, be based on slavery, but it is also based on the failure of the country to take effective steps since slavery to undermine the structural racial inequality that slavery put in place. From the latter part of the nineteenth century through the fi rst half of the twentieth century, the Jim Crow system continued to keep Blacks “in their place,” and even during and after the civil rights era no policies were adopted to dismantle the racial hierarchy that already existed. An important part of the story of racial inequality today is the history of housing and lending discrimination in the second half of the twentieth century (McCarthy 2002; 2004). Home equity, for many Americans, is a very important source of wealth, and the decades after World War II were ones of rapid home equity growth. They were the decades that saw the creation of a large, mostly suburban, middle class. But the middle class that was created was also mostly White, and this was due largely to government policies that (in many cases intentionally) excluded Blacks from the opportunities to get into the home market and benefi t from home equity growth. In this paper we argue that recent housing and lending discrimination constitutes an important basis for black reparations.. (shrink)

Will a synthesis of developmental and evolutionary biology require a focus on the role of nongenetic resources in evolution? Nongenetic variation may exist but be hidden because the phenotypes are stable (developmentally canalized) under certain background conditions. In this case, those differences may come to play important roles in evolution when background conditions change. If this is so, then a focus on the way that developmental resources are made reliable, and the ways in which reliability fails, may prove to be (...) of crucial importance to linking developmental and evolutionary biology. †To contact the author, please write to: 208 Hovland Hall, Philosophy Department, Oregon State University, Corvallis, OR 97331‐3902; e‐mail: [email protected].

We are addressing this letter to the editors of Philosophical Psychology after reading an article they decided to publish in the recent vol. 33, issue 1. The article is by Nathan Cofnas and is entitled “Research on group differences in intelligence: A defense of free inquiry” (2020). The purpose of our letter is not to invite Cofnas’s contribution into a broader dialogue, but to respectfully voice our concerns about the decision to publish the manuscript, which, in our opinion, fails to (...) meet a range of academic quality standards usually expected of academic publications.

Recently, an article by Toshiko Tanaka, Takao Yamamoto, and Masahiko Haruno garnered a fair bit of media attention; in “Brain response patterns to economic inequity predict present and future depression indices”, they reported research that purported to show that “pro-social” individuals were more upset by unequal outcomes that didn’t directly disadvantage them than were “individualists.” Further, being pro-social was associated with a higher chance of developing depression. They linked this research with research showing that economic inequality is associated with poor (...) health outcomes, including higher rates of depression.

The works of the later Wittgenstein resonate with aspects of the pragmatist tradition in American philosophy. Davidson’s work is similarly informed. We argue that because of their association with the pragmatist tradition, their work can be put to use by philosophers interested in social justice issues, including, for example, feminism, and critical race theory. Philosophers concerned with social justice continue to struggle between the extremes of an untenable foundationalism and a radical relativism. Given their holistic understanding of knowledge, meaning and (...) communication, the work of Wittgenstein and Davidson is particularly suited to dissolving the foundationalist/relativist dichotomy. We explore how this and other features of their work facilitates philosophy for social change. (shrink)

Questions traditionally answered by philosophers are now being tackled by prominent scientists. As the cultural influence of science and technology continues to grow, what room, if any, is left for philosophy? Three philosophers—Dr. Jonathan Kaplan, Dr. Massimo Pigliucci, and Dr. Leonard Finkelman —explore issues related to the philosophy of science, including how philosophy has contributed to scientific progress, why philosophy continues to be important to science, and why there remain questions that only philosophy can answer. The panelists represent four generations (...) of an academic lineage: Dr. Kaplan was Dr. Pigliucci's dissertation advisor, Dr. Pigliucci was Dr. Finkelman's dissertation advisor, and Evan Tracy is a student of Dr. Finkelman.

Attempts to explain human behavior that appeal to economic rationality share many of the same ontological as- sumptions and methodological practices that the so-called ‘adaptationist program’ in biology was criticized for. This program in biology was largely abandoned by biologists as poorly motivated, and replaced with the active testing of both adaptive and non-adaptive hypotheses regarding the spread and maintenance of traits in populations. This development was largely welcome by the biological community, despite having required the development of new tools, (...) both conceptual and method- ological. Many analysts of contemporary microeconomic practice criticize the assumptions and practices employed therein as similarly poorly motivated. Close attention to these criticisms reveal them to have more than superficial similarities to the critiques of adaptationism in biology. These similarities extend to some macroeconomics researchers recent suggestions of ways that hypotheses regarding the causes of people’s actions might be tested; as yet, however, these suggestions have not been embraced by the field as a whole. By attending to the ways in which biological practice has moved beyond the adaptationist program, similar changes in economic practice may be motivated. (shrink)

In Understanding Evolution, Kostas Kampourakis has two related goals. The first is to demonstrate that there are conceptual hurdles to properly understanding evolutionary theory. Kampourakis argues that educators, and other promoters of evolutionary theory, have underestimated how difficult it is to understand evolutionary theory and have tended to treat some gaps in understanding that are in fact the result of conceptual difficulties as if they were instead the result of, e.g., religious intolerance to the theory. This, he thinks, is a (...) mistake. Once we accept that there are aspects of evolutionary theory that are counterintuitive, and that a host of cognitive biases make accepting evolutionary biology difficult, we will be, he argues, in a better position to present compelling argument that can work against these biases. That is the second goal of the book—to present an explanation of contemporary evolutionary theory that is attentive to the ways in which the theory might seem problem .. (shrink)

Abstractabstract:Leviticus 25 details legislation for the regularized practice of economic relief in sabbatical and jubilee years. Earlier scholarship described the jubilee legislation as utopian in order to question its feasibility. In contrast, this article employs the term as a critical lens through which to better appreciate the shape and character of the jubilee legislation. Building on scholarship on utopian literature as well as work on the role of law in utopian literature, the author argues that the author of Leviticus 25 (...) employs distinctive economic practices, an idyllic description of Israelite society, and unique terminology and ritual practices for the jubilee in order to present its plausible utopian economic vision for Israelite society. This utopian legislation envisions a credible alternative to the existing practices of ancient Israelite society even if its specific historical context is difficult to determine and its specific statutes could be regarded as dystopian by some members of this society.
