HOORAY for Basic Science Research! And duck genitalia

Basic science =  scientific questions that are founded in understanding theory, or the natural world around us

Applied science = scientific research that is directly applicable to humans. i.e. Cancer research

The last few years of financial crisis have seen a rise in criticism over basic scientific research. NPR does a great job of summarizing the criticisms and explaining why seeking to understand duck genitalia is a solid biological question.

A guide to the science and pseudoscience of A Troublesome Inheritance, part III: Has natural selection produced significant differences between races?

This is the third in a series of guest posts in which Chris Smith will examine the evolutionary claims made in Nicholas Wade’s book A Troublesome Inheritance. You can read part I here, and part II here. Chris is an Associate Professor of Evolutionary Ecology at Willamette University. He uses population genetic approaches to understand coevolution of plants and insects, and he teaches the interdisciplinary course “Race, Racism, and Human Genetics” with Emily Drew.

A Troublesome Inheritance was published in 2014 by Penguin Books. Cover image via Google Books.

This spring former New York Times science writer, Nicholas Wade, released his latest book on human evolution, A Troublesome Inheritance: Genes, Race, and Human History. In it, Wade argues that genetic studies completed in the eleven years since the Human Genome Project was completed reveal real and important differences between human races. Unsurprisingly, the book’s release has been met with a sharply divided critical reception.Whereas the book has been widely embraced by those on the political right, and by the white identity movement, it has been panned by anthropologists, evolutionary biologists, and population geneticists. For the last two weeks at Nothing in Biology Makes Sense, I’ve been looking in depth at the literature that Wade uses to support his ideas. Last week I considered Wade’s argument that natural selection acting on the MAO-A gene – a neurotransmitter implicated in aggression and impulsivity – has led to behavioral differences between races. This week I will consider Wade’s larger claim that natural selection has produced numerous differences between races.

Throughout the book Wade continually repeats the mantra that natural selection on humans has been “recent, copious, and regional.” It would be hard to find an evolutionary biologist that would disagree with these rather vague pronouncements. Indeed, there are a multitude of studies showing that natural selection has acted on humans, and there is persuasive evidence that selection has caused evolutionary changes in human populations as we have adapted to diverse environments over the course of the last several thousand years (see, for example, Yi et al., 2010).

However, scratching the surface reveals that when he says that natural selection has been “recent, copious, and regional,” what Wade actually means is that natural selection has been “radical, complete, and racial.” By Wade’s account, natural selection has dramatically reshaped the human genome, producing major differences between races. This much more dramatic interpretation is entirely unsupported by the literature, however. In truth, Wade vastly overstates the portion of the human genome that shows evidence for natural selection, and where there has been recent natural selection acting on humans, its effect has primarily been to create genetic differences between members of the same race, and similarities between people of different races.

A guide to the science and pseudoscience of A Troublesome Inheritance, part II: Has natural selection favored violent behavior in some human populations?

This is the second in a series of guest posts in which Chris Smith will examine the evolutionary claims made in Nicholas Wade’s book A Troublesome Inheritance. You can read part I here. Chris is an Associate Professor of Evolutionary Ecology at Willamette University. He uses population genetic approaches to understand coevolution of plants and insects, and he teaches the interdisciplinary course “Race, Racism, and Human Genetics” with Emily Drew.

Last week at Nothing In Biology Makes Sense, I began critiquing Nick Wade’s latest book, A Troublesome Inheritance. The book has produced a firestorm of criticism, largely because it argues that evolution has produced significant cultural and behavior differences between races.

Wade makes many sweeping claims, among them: that natural selection has made the English inherently fiscally prudent and more likely to defer gratification by saving for tomorrow, that events early in the history of Judaism caused the Jews to evolve features predisposing them to careers in banking, and that genetic variation in certain neurochemicals has made Africans inherently more violent.

Wade hangs these seemingly bizarre conclusions on the mantle of modern population genetics, which he claims confirms the existence of ‘three primary races,’ that have evolved real and significant cultural differences between them. By heavily referencing the scientific literature, Wade manages, as Mike Eisen put it, to “give the ideas that he presents… the authority of science… What separates Wade’s theories – in his own mind – from those of a garden variety racist is that they are undergirded by genetics.”

A guide to the science and pseudoscience of A Troublesome Inheritance, part I: The genetics of human populations

This is the first in a series of guest posts in which Chris Smith will examine the evolutionary claims made in Nicholas Wade’s book A Troublesome Inheritance.

Last month the former New York Times writer Nicholas Wade released his latest book on human evolution, A Troublesome Inheritance: Genes, Race, and Human History (2014, Penguin Press). In it, Wade argues that the genomic data amassed over the past ten years reveal real and meaningful biological differences between races, and that these differences explain much of the cultural and socioeconomic differences between people. If you haven’t read a newspaper or picked up a magazine in the last month, you may not have noticed that Wade’s book has—predictably—prompted intense and impassioned reaction from scientists, sociologists, and commentators from across the political spectrum. Writing for the Wall Street Journal, Charles A. Murray, author of The Bell Curve, called Wade’s book, “A delight to read … [that] could be the textbook for a semester’s college course on human evolution.” On the other hand, Arthur Allen, in his review for the New York Times, predicts that many readers will find Wade’s book to be, “a rather unconvincing attempt to promote the science of racial difference.”

View from Kamiak Butte. Outside Moscow, ID.

A lot of pixels have been spilled on the subject of the adjunct crisis in academia. For those of you who don’t know what that is, it refers to the explosive growth in the use of adjunct faculty to teach courses at colleges and universities in the United States. These faculty are hired on a course by course, semester by semester basis. They receive no benefits and don’t have a shred of job security. By some estimates an average “full-time” adjunct faculty member teaching 8 courses a year (3 each semester and 2 in the summer, perhaps?) would make less than $30,000 a year and it’s thought that adjunct faculty are now doing 70% of the teaching at higher education institutions in the US.

Much of the discussion of this issue has focused on the perceived fundamental unfairness of employing highly educated professionals in such an absurd fashion, or on the pyramid scheme-y aspects of graduate programs that chew up students and spit them into this cesspool of underemployment. In the comments sections of these pieces, there is an ever-present retort, presumably emanating from those free market-loving capitalists among us, that if adjunct faculty hate their plight so much, they should change career paths.

In response to this, I want to use a recent post at this blog to highlight a slightly less well covered aspect of the issue and the other side of that coin: when you offer shitty compensation, you might just get shitty employees.

The gold-star creationist?

2010.02.15 - Life Sciences South

Academic freedom is a bedrock principle of higher education—part of the point of having classes taught by working scholars is that, at the university level, students should be exposed to the interplay of ideas at the cutting edge of each field of study, and so professors should have latitude to explore controversial topics and defend their own perspectives.

But there are limits to that principle. Common sense, and the need to organize prerequisites across a multi-year curriculum, dictates that even a tenured professor would get into trouble if she devoted her entire introductory chemistry course to a critical reading of The Lord of the Rings. In a (maybe) less extreme example, a professor who spent an astronomy class arguing that there is a scientific basis to the Zodiac would, at the very least, get a talking-to from his department chair. In order to meaningfully teach a given class, there are topics that need to be covered—and there is material that has no legitimate place in the syllabus.

This is why I was so surprised to learn, a few weeks ago, that the University of Idaho—the institution where I earned my Ph.D., where Noah earned his Master’s degree and Sarah earned both her B.S. and Master’s—has hired someone who believes that the Earth was created over the course of six days about six thousand years ago, to teach an introductory microbiology course.

Why study whether we evolved this way?

baby i was born this way

John Corvino, the chair of the Philosophy Department at Wayne State University, has recently published a book, What’s Wrong With Homosexuality, which systematically knocks down objections to the equality of LGBTQ folks. He’s been discussing major points from the book in a series of clever and widely-circulated videos, and I just recently discovered that, in an episode about the biological basis of sexual orientation, he talks about that review article proposing a possible epigenetic basis for sexual orientation that I discussed here a few months ago.

Full disclosure: I found Corvino’s post, actually, because he linked to my piece about the epigenetics paper, and he did so while paying it what I consider the highest compliment it’s possible to pay a science blogger: “A nice explanation of the paper can be found here.” Which: look at me blushing.

But Corvino comes at the question from a somewhat different angle than a biologist: he says it really doesn’t matter whether there’s an inborn basis to sexual orientation.

Does science promote morality?

Almost a year ago today, I wrote my first post here at Nothing in Biology Makes Sense!.  The post, titled ‘The Data on Science and Religion‘, discussed a article in Science that investigated whether analytical thinking promoted religious disbelief.  I thought it fitting that my post today would tackle a new article, just published in PLoS One that asks whether analytical thinking also makes you more moral.

The authors of the article, Christine Ma-Kellams and Jim Blascovich, used a series of four experiments to ask whether there was a link between exposure to science and moral behavior.  In the first experiment, the authors examined how previous exposure to scientific thinking influenced perceptions of moral behavior.  Participants were asked to read a short story describing a date rape situation and rate how wrong the behavior was on a scale of 1-100, where 100 is considered completely wrong.  They were then asked, on a scale of 1-7, how much they ‘believe’ in science.

To avoid confounding past experiences, the following three experiments manipulated the participants recent exposure to scientific thinking by asking them to play a word game that either contained scientific vocabulary (i.e. hypothesis, scientists, etc.) or control vocabulary (i.e. shoes, paper, etc.) and then complete one of three alternative tasks aimed to measure morality.  The second study repeated the same moral judgement scenario as their first experiment.  The third study asked participants to report the likelihood that they would engage in certain activities in the following month.  Those activities fell into two categories: (1) prosocial behaviors that benefit others, such as giving blood and (2) control activities with no benefit to others, such as going to the movies.  Finally, the forth study measured actual moral behavior by giving the participants $5 and asking them to split it (in any manner they desired) between themselves and another anonymous participant.

Friday Coffee Break, Official Springtime Edition

springcoffee

Every Friday at Nothing in Biology Makes Sense! our contributors pass around links to new scientific results, or science-y news, or videos of adorable wildlife, that they’re most likely to bring up while waiting in line for a latte.

With the official start of Spring this week, at least depending on where you are.  For me, I’m currently sitting in Ithaca, NY where the high for the day is still only squeaking into the above freezing range which only makes me miss Richmond, VA right now all the more.  So without further adieu, which is apparently my new catch phrase, your links for the week.

To start things off on a light and happy note.  Sarah has some wonderful news that she passed her dissertation defense!!  She is so excited, as she should be, that her link this week is a ton of dancing GIFs.  Of note, she things either Carlton or Ace Ventura match her mood best.  Congrats Sarah!

This week CJ wonders about the possibility of a gender gap in pain perception as discussed in the NYTimes article.  She also thought this article gave a good break down of the process of becoming tenured and is indeed quite helpful (and makes me glad to be in the field that I am in).  And finally, an opinion piece on why De-extinction would not work.

From Jeremy, a piece from the blog Why Evolution is True on why science writing is tedious and often boring and what it takes to write good science.

From Amy, a depressing story on the passage of an amendment limiting the funding for NSF research regarding political science and the letter from Senator Tom Coburn justifying this measure.

Finally, I’d like to end things with a video.  I’m a big fan of TED talks and also of U2, so when I saw that Bono gave a TED talk about his passion of helping to fight to end poverty I thought it was worth a look.  I loved his analogy of how poverty could end in as short a time period as about 3 more Rolling Stones farewell tours.

Barack Obama in Lima - November 2nd

President Obama at a rally in Lima, Ohio, on Friday.

Cross-posted from Denim and Tweed.

You may have heard that there’s an election happening in the United States today. It’s been ten months of “campaign season” since the early Republican party primary elections in Iowa and New Hampshire, and the two presidential campaigns and their various allies have raised and spent going on two billion (billion!) dollars on advertising and campaigning and probably also consultants’ fees.

This seems like an awfully expensive and inefficient way to choose someone to run a government, which is to say an awfully expensive and inefficient way to work together to decide upon and achieve common goals. Winston Churchill famously noted that democracy is the worst form of government “except all those other forms that have been tried from time to time.” But Churchill was really only talking about democracy in comparsion to other human forms of government. The living world contains all sorts of examples of individuals coordinating their actions for mutual benefit, and none of them need political action committees to do it.

Is there a better approach to group organization somewhere else on the tree of life? Let’s consider a few options:
