Why I Study Duck Genitalia
Fox News and other conservative sites miss the point of basic science.


In the past few days, the Internet has been filled with commentary on whether the National Science Foundation should have paid for my study on duck genitalia, and 88.7 percent of respondents to a Fox news online poll agreed that studying duck genitalia is wasteful government spending. The commentary supporting and decrying the study continues to grow. As the lead investigator in this research, I would like to weigh in on the controversy and offer some insights into the process of research funding by the NSF.

My research on bird genitalia was originally funded in 2005, during the Bush administration. Thus federal support for this research cannot be connected exclusively to sequestration or the Obama presidency, as many of the conservative websites have claimed.

Since Sen. William Proxmire's Golden Fleece awards in the 1970s and 1980s, basic science projects are periodically singled out by people with political agendas to highlight how government “wastes” taxpayer money on seemingly foolish research. These arguments misrepresent the distinction between and the roles of basic and applied science. Basic science is not aimed at solving an immediate practical problem. Basic science is an integral part of scientific progress, but individual projects may sound meaningless when taken out of context. Basic science often ends up solving problems anyway, but it is just not designed for this purpose. Applied science builds upon basic science, so they are inextricably linked. As an example, Geckskin™ is a new adhesive product with myriad applications developed by my colleagues at the University of Massachusetts. Their work is based on several decades of basic research on gecko locomotion.

Whether the government should fund basic research in times of economic crisis is a valid question that deserves well-informed discourse comparing all governmental expenses. As a scientist, my view is that supporting basic and applied research is essential to keep the United States ahead in the global economy. The government cannot afford not to make that investment. In fact, I argue that research spending should increase dramatically for the United States to continue to lead the world in scientific discovery. Investment in the NSF is just over $20 per year per person, while it takes upward of $2,000 per year per person to fund the military. Basic research has to be funded by the government rather than private investors because there are no immediate profits to be derived from it.

Because the NSF budget is so small, and because we have so many well-qualified scientists in need of funds, competition to obtain grants is fierce, and funding rates at the time this research was funded had fallen well below 10 percent. Congress decides the total amount of money that the NSF gets from the budget, but it does not decide which individual projects are funded—and neither does the president or his administration. Funding decisions are made by panels of scientists who are experts in the field and based on peer review by outsiders, often the competitors of the scientists who submitted the proposal. The review panel ranks proposals on their intellectual merits and impacts to society before making a recommendation. This recommendation is then acted upon by program officers and other administrators, who are also scientists, at the NSF.

This brings us back to the ducks. Male ducks force copulations on females, and males and females are engaged in a genital arms race with surprising consequences. Male ducks have elaborate corkscrew-shaped penises, the length of which correlates with the degree of forced copulation males impose on female ducks. Females are often unable to escape male coercion, but they have evolved vaginal morphology that makes it difficult for males to inseminate females close to the sites of fertilization and sperm storage. Males have counterclockwise spiraling penises, while females have clockwise spiraling vaginas and blind pockets that prevent full eversion of the male penis.

Our latest study examined how the presence of other males influences genital morphology. My colleagues and I found that it does so to an amazing degree, demonstrating that male competition is a driving force behind these male traits that can be harmful to females. The fact that this grant was funded, after the careful scrutiny of many scientists and NSF administrators, reflects the fact that this research is grounded in solid theory and that the project was viewed as having the potential to move science forward (and it has), as well as fascinate and engage the public. The research has been reported on positively by hundreds of news sites in recent years, even Fox news. Most of the grant money was spent on salaries, putting money back into the economy.

The commentary and headlines in some of the recent articles reflect outrage that the study was about duck genitals, as if there is something inherently wrong or perverse with this line of research. Imagine if medical research drew the line at the belt! Genitalia, dear readers, are where the rubber meets the road, evolutionarily. To fully understand why some individuals are more successful than others during reproduction, there may be no better place to look. The importance of evolutionary research on other species’ genitalia to the medical field has been recently highlighted in the Journal of Sexual Medicine. Generating new knowledge of what factors affect genital morphology in ducks, one of the few vertebrate species other than humans that form pair bonds and exhibit violent sexual coercion, may have significant applied uses in the future, but we must conduct the basic research first. In the meantime, while we engage in productive and respectful discussion of how we envision the future of our nation, why not marvel at how evolution has resulted in such counterintuitive morphology and bizarre animal behavior.
