Defining Evolution in Anthropology Textbooks

Here's one of the most interesting articles in the current edition of Evolution: Education and Outreach.

White, J., Tollini, C.D., Collie, W.A., Strueber, M.B., Strueber, L.H., and Ward, J.W. (2009) Evolution and University-level Anthropology Textbooks: The “Missing Link”? Evo. Edu. Outreach 2:722–737 [doi: 10.1007/s12052-009-0176-6]

Abstract: Although studies analyzing the content of evolution curriculum usually focus on courses within the context of a biological sciences department or program, research must also address students and courses outside of the biological sciences. For example, using data solely from biological courses will not fully represent the scope of coverage of evolution in university education, as other fields, like anthropology, also utilize evolutionary principles. We analyzed the content of 31 university-level anthropology textbooks for the following: (1) presence of a definition of evolution in various sections of the textbooks, (2) accuracy and consistency of the definitions provided in the textbook sections, and (3) differences between textbooks for cultural and physical anthropology. Results of this study suggest that anthropology textbooks do not necessarily (1) provide a single definition of evolution or (2) provide an accurate, “baseline” definition of evolution when present. Additionally, substantive differences were observed between definitions provided in different sections within a single textbook, as well as between textbooks written for cultural anthropology and physical anthropology/archaeology courses. Given the inclusion of anthropology courses in general education curriculum at the university-level, we conclude that this situation may further exacerbate the misunderstanding of the basic tenets of evolution that university students have been repeatedly shown to demonstrate. We stress the role of the instructor in choosing textbooks that provide accurate information for students, as well as the responsibility they hold in providing a concise, accurate definition of evolution in social sciences courses.

The authors refer to an earlier study by Linhart (1997) who examined definitions of evolution in biology textbooks.

In our literature search, we were able to locate only one study that directly addressed the coverage of evolution in textbooks. Linhart (1997) focused on textbooks designed for one of the following six courses in the biological sciences: general biology (for majors and non-majors), evolution, genetics, paleontology, ecology, and systematics. He restricted his sample to 50 textbooks that had multiple editions and a sizable market share, and he located at least some of these textbooks using colleagues’ recommendations. He analyzed the content of the glossary entry for evolution in each textbook, as well as the material in any pages listed in an index entry for evolution, and compared these data against a definition of evolution he constructed after reviewing the literature:

Evolution is said to have occurred within a species, lineage, or population when measurable changes in various morphological, physiological, behavioral, or biochemical characteristics can be detected. These characteristics must be at least partly under genetic control. The genetic change(s) can occur as a
consequence of processes such as migration, mutation, genetic drift or bottleneck, natural selection, and nonrandom mating. Genetic changes within different populations of a species can lead to differences among lineages, and sometimes to the origin of new species...Evolution is not a synonym of natural selection. Nor is evolution a process that leads inevitably to increased or improved adaptation, or to greater reproductive success. Evolution does not imply a progressively closer fit between a population and its environment. Finally, evolution does not involve predictable or irrevocable changes from simple to more complex forms or toward some sort of perfection (Linhart 1997: 387).

While he found variation between the textbooks written for the six different courses in his sample, his findings indicated that the majority of all of the textbooks equated evolution with natural selection or adaptation and did not describe evolution in much detail. Linhart (1997) expressed much concern regarding the content of the definition of evolution in these textbooks, arguing that many students will have an inaccurate or incomplete view of evolution unless they are provided with additional material.

I agree with the problems that Linhart outlines and I agree that evolution needs to be defined as a process that involves genetic change and populations. It's very important that evolution should be defined in a way that allows for multiple mechanisms such as natural selection and random genetic drift.

Most of the biology textbooks I've read do an adequate job of defining evolution but I haven't covered as many textbooks as Linhart.

It's disappointing that biology textbooks and anthropology textbooks do such a poor job of defining—and presumably explaining—evolution. Is it any wonder that the general public is scientifically illiterate when we can't even get it right in the textbooks?

Evolution According to Niles Eldredge

 

I've read all of the books by Niles Eldredge. He's one of my favorite science authors [Good Science Writers: Niles Eldredge]. However, I've never really understood exactly what he means when he talks about evolution. He's not a molecular biologist or a geneticist but does he understand the basics of these disciplines? Does he think of evolution as a branch of population genetics or something else? Does he know about random genetic drift?

Some of these questions have been answered in an article that he co-authors with his son in the latest issue of Evolution: Education & Outreach. This is a journal dedicated to teaching evolution correctly. The article outlines a universal evolution curriculum for all grades from kindergarten to university [Lessons from EEO: Toward a Universal Evolutionary Curriculum].

Abstract We propose a human-centered evolutionary curriculum based around the three questions: Who am I? Where do I come from? How do I fit in? We base our curriculum on our experiences as an evolutionary biologist/ paleontologist (NE) and as a secondary level special education science teacher (GE)—and not least from our joint experience as co-editors-in-chief of this journal. Our proposed curriculum starts and ends with human biology and evolution, linking these themes with topics as diverse as the “tree of life” (systematics), anthropology, Charles Darwin, cultural evolution, ecology, developmental biology, molecular evolution/genetics, paleontology, and plate tectonics. The curriculum is “universal” as it is designed to be taught at all levels, K–16. The curriculum is flexible: “modules” may be expanded and contracted, reordered, or modified to fit specific grade level needs—and the requirements and interests of local curricula and teachers. We further propose that students utilize workbooks from online or printed sources to investigate the local answers to the general questions (e.g., “Who am I?”), while classroom instruction is focused on the larger scale issues outlined in the modules of our curriculum.

I don't like the idea of teaching evolution from a human-centered perspective. Our students are certainly used to thinking of biology only in terms of themselves, but isn't it our goal as educators to teach them that this is wrong?

It's the age-old question of whether the best way of teaching is to cater to student misconceptions or confront them.

A key part of any evolution curriculum is defining evolution. I prefer a scientific definition that allows us to distinguish evolution from other process that may look like evolution. The minimal definition is derived from population genetics and it allows us to recognize that different frequencies of blood groups in different human populations is evolution [What Is Evolution?].

Eldredge prefers a different definition in his evolutionary curriculum ...

What is “evolution?” Evolution is the testable, scientific idea that all species of life on Earth are descended from a common ancestor living billions of years ago since life first began on Earth. You can think of evolution as the history of life on Earth—or even as the fate of genetic information through time.

Module 3: What Is Evolution? How Do Humans Fit into the History of Life?

I've always taught that evolution is a process and that it's distinctly different from the history of life. It's like the difference between gravity and the history of our solar system. The formation of our solar system was a unique event that relied upon, and can be explained by, gravity and other general processes. Similarly, the history of life on Earth is a unique event. It can be explained by evolution and other processes but it's not the same as "evolution."

As far as I know, there are no evolutionary biology textbooks that define evolution as the history of life. The Eldredges are proposing a curriculum that's out of sync with most pedagogical approaches to evolution. Is this a better way to teach evolution? I don't think so.

Module 3 also covers the mechanisms of evolution. Adaptation and natural selection are mentioned but the authors go on to say that natural selection is not the only evolutionary process. The others are: speciation, punctuated equilibria, and mass extinctions.

I've always suspected that Niles Eldredge discounts random genetic drift as a legitimate process of evolution. This confirms my suspicion.

I'm very concerned about the content of this article and it's publication in a journal that's devoted to evolution education. If this is what the experts on evolution education are touting as the ideal curriculum then there are only two possible conclusions: (1) they aren't experts, or (2) I'm dead wrong about everything that I've been teaching.

I'm almost afraid to open up the comments on this posting for fear that (2) is the correct answer.

Comparison and Adaptation

 
As most of you know, Richard Dawkins is not a fan of the Spandrels paper by Gould and Lewontin [A Critique of the Adaptationist Programme]. A reader has alerted me to a comment that Richard Dawkins posted on Jerry Coyne's blog.

Dawkins said [I was there ...].

I was there (one of the speakers) at the London meeting of the Royal Society, where the Spandrels paper was first presented (by Gould; Lewontin didn’t come). Before Gould spoke, the talk by Clutton-Brock and Harvey substantially anticipated the Spandrels paper and undermined its central thesis. All of us were eager to hear how Gould would deal with Clutton-Brock and Harvey’s devastating critique of what they guessed (from previous publications) he would say. In the event, Gould totally ignored Clutton-Brock and Harvey, and gave his prepared paper, playing for horse laughs from the gallery, as if nothing had happened. It was the beginning of my disillusionment with Gould, whom I had previously respected. Please, if you read the Spandrels paper, look first at the Clutton-Brock and Harvey paper, in the same volume published by the Royal Society, 1979.

I had not heard of this paper by Clutton-Brock and Harvey and I'm not familiar with their work. Here's the reference and the abstract—it doesn't look to me like a devestating critique of Gould and Lewonton's paper.

Clutton-Brock, T.H. and Harvey, P.H. (1979) Comparison and Adaptation. Proc. R. Soc. Lond. B 205:547-565. [doi: 10.1098/rspb.1979.0084]

It has sometimes been suggested that the term adaptation should be reserved for differences with a known genetic basis. We argue that adaptation should be defined by its effects rather than by its causes as any difference between two phenotypic traits (or trait complexes) which increases the inclusive fitness of its carrier. This definition implies that some adaptations may arise by means other than natural selection. It is particularly important to bear this in mind when behavioural traits are considered. Critics of the 'adaptationist programme' have suggested that an important objection to many adaptive explanations is that they rely on ad-hoc arguments concerning the function of previously observed differences. We suggest that this is a less important problem (because evolutionary explanations generally claim some sort of generality and are therefore testable) than the difficulties arising from confounding variables. These are more widespread and more subtle than is generally appreciated. Not all differences between organisms are directly adapted to ecological variation. The form of particular traits usually constrains the form or value that other traits can take, presenting several obstacles to attempts to relate variation in morphological or behavioural characteristics directly to environmental differences. We describe some of the repercussions of differences in body size among vertebrates and ways in which these can be allowed for. In addition, a variety of evolutionary processes can produce non-adaptive differences between organisms. One way of distinguishing between these and adaptations is to investigate adaptive trends in phylogenetically different groups of species.

Vegetarian Nobel Laureates

I'm sure you've all been dying to know how many Nobel Laureates were vegetarians. Well, here's the answer. It was was on the back of a flyer received by one of the Skepchicks [An Appeal to Chickens and Other Logical Fallacies]. She's asking you to review the front part of the flyer to see how many logical fallacies you can identify.

It's interesting that only one Nobel Laureate won the Noble Prize for Physiology or Medicine. I guess the "logic" behind being a vegetarian isn't as obvious to biologists as it is to writers of fiction.

What Can't You Do in the House of Commons?

 
Almost anything goes in Ontario's House of Commons and debates can be rather lively. However, tradition (and House rules) state that you cannot accuse someone of lying. Here's what happens if you break that rule.



Ted Chudleigh is the Conservative MPP for Halton—a district that includes Oakville and Milton. He's ranting about a proposal to harmonize the GST and PST taxes.

Jennifer Smith lives in Milton and she's on the case. A little digging led her to this quotation from a speech by Ted Chudleigh in the House of Commons only 14 months ago [Ted Chudleigh on the HST: What a Difference a Year Makes].

Taxing businesses for their input costs is also a negative thing to do in an economy. It would be far better if we could find a way to harmonize the PST with the GST." (October 2, 2008 - Legislative Assembly Hansard)

Oh, dear. Is it possible that Mr. Chudleigh is a liar? Or is he just a hypocrite?

A Critique of the Adaptationist Programme

The Royal Society of Britain has opened access to a number of classic papers that have been published in Proceedings of the Royal Society. One of them is ...

Gould, S. J. and Lewontin, R.C. (1979) The Spandrels of San Marco and the Panglossian Paradigm: A Critique of the Adaptationist Programme. Proc. R. Soc. Lond. B 205:581-598. [doi: 10.1098/rspb.1979.0086]

Abstract: An adaptationist programme has dominated evolutionary thought in England and the United States during the past 40 years. It is based on faith in the power of natural selection as an optimizing agent. It proceeds by breaking an organism into unitary 'traits' and proposing an adaptive story for each considered separately. Trade-offs among competing selective demands exert the only brake upon perfection; non-optimality is thereby rendered as a result of adaptation as well. We criticize this approach and attempt to reassert a competing notion (long popular in continental Europe) that organisms must be analysed as integrated wholes, with Bauplane so constrained by phyletic heritage, pathways of development and general architecture that the constraints themselves become more interesting and more important in delimiting pathways of change than the selective force that may mediate change when it occurs. We fault the adaptationist programme for its failure to distinguish current utility from reasons for origin (male tyrannosaurs may have used their diminutive front legs to titillate female partners, but this will not explain why they got so small); for its unwillingness to consider alternatives to adaptive stories; for its reliance upon plausibility alone as a criterion for accepting speculative tales; and for its failure to consider adequately such competing themes as random fixation of alleles, production of non-adaptive structures by developmental correlation with selected features (allometry, pleiotropy, material compensation, mechanically forced correlation), the separability of adaptation and selection, multiple adaptive peaks, and current utility as an epiphenomenon of non-adaptive structures. We support Darwin's own pluralistic approach to identifying the agents of evolutionary change.

If you haven't read this paper by now then download it and read it carefully. It's the most important paper to read if you are interested in evolution.

Jerry Coyne agrees, "Read the rest; it’s certainly one of the most important papers in modern evolutionary biology." [It’s a spandrel (sort of . . .)!].

He also says,

This paper is famous because the authors were famous, because it’s very well written, but most of all because it posed a direct attack on the “Panglossian paradigm”: the view that sociobiology wants to explain all traits, particularly human behaviors, as the direct products of selection. This paper has been the subject of furious discussion and at least one book. In my view, the paper made some valid points but went overboard in its criticism of the adaptationist program, which, after all, has produced lots of insights about evolution. I knew Gould, who was on my thesis committee, and it always seemed like pulling teeth to get him to admit that natural selection was even a relatively important force in evolution. If pressed, he would, but Gould always preferred (perhaps for political reasons) to emphasize the limitations of selection. Lewontin was not nearly so extreme.

It's true that the adaptationists have produced some valuable insights when the problem they are examining is actually an adaptation. However, this isn't as significant as you might imagine. Think of it like this. Everything looks like a nail when you have a large hammer in your hand. The fact that some things actually turn out to be nails is no excuse for blindly whacking at everything that sticks up.

Gould and Lewontin advocated a pluralist position where many different kinds of explanations should be considered. They note that Darwin himself was not committed to natural selection as the only possible mechanism of evolution.

Since Darwin has attained sainthood (if not divinity) among evolutionary biologists, and since all sides invoke God's allegiance, Darwin has often been depicted as a radical selectionist at heart who invoked other mechanisms only in retreat, and only as a result of his age's own lamented ignorance about the mechanisms of heredity. This view is false. Although Darwin regarded selection as the most important of evolutionary mechanisms (as do we), no argument from opponents angered him more than the common attempt to caricature and trivialize his theory by stating that it relied exclusively upon natural selection. In the last edition of the Origin, he wrote (1872, p. 395):

"As my conclusions have lately been much misrepresented, and it has been stated that I attribute the modification of species exclusively to natural selection, I may be permitted to remark that in the first edition of this work, and subsequently, I placed in a most conspicuous position-namely at the close of the introduction-the following words: "I am convinced that natural selection has been the main, but not the exclusive means of modification." This has been of no avail. Great is the power of steady misinterpretation."

[Hat Tip: Pharyngula: Oldie moldies that are pretty darned fascinating]

On Determining the Structure of a Protein

Michael Clarkson is a biotech postdoc who blogs at Discount Thoughts. One of his recent thoughts is Don't look for "the" structure. He is referring to the fact that the crystal structure of a protein doesn't actually represent the only structure that the protein can adopt.

The figure shown here illustrates one of the problems with referring to the structure of a protein. This is a representation of an NMR structure of bovine ribonuclease A. It shows that various parts of the protein exist in several different conformations. The actual protein structure is a composite of all these structures in equilibrium with each other.

These conformation could be considered "breathing" and you may think they're not important. However, there are many cases where the conformations of a protein are quite different. We are familiar with allostery, where the conformation of a protein changes when it's bound to a ligand, but the are also examples where two very different structures exist in equilibrium in the absence of ligand.

Read his blog posting and keep in mind that proteins are dynamic structures and not static rigid crystals.

150 Years Ago

On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life was published 150 years ago on November 24, 1859. The publisher, John Murray, had already taken orders for 1,500 copies so the initial printing of 1,250 copies was sold out immediately.

Although much remains obscure, and will long remain obscure, I can entertain no doubt, after the most deliberate study and dispassionate judgment of which I am capable, that the view which most naturalists entertain, and which I formerly entertained—namely, that each species is independently created—is erroneous. I am fully convinced that species are not immutable; but that those belonging to what are called the same genera are lineal descendants of some other and generally extinct species, in the same manner as the acknowledged varieties of any one species are descendants of that species. Furthermore, I am convinced that Natural Selection has been the main but not the exclusive means of modification.
