The BBC has compiled what looks to be an absolutely visually stunning television series, titled ‘Human Planet.’  The footage is said to contain video from 80 different locations, highlighting the relationship of humans to various ecological conditions.1 The description from the website:

Uniquely in the animal kingdom, humans have managed to adapt and thrive in every environment on Earth. Each episode takes you to the extremes of our planet: the arctic, mountains, oceans, jungles, grasslands, deserts, rivers and even the urban jungle. Here you will meet people who survive by building complex, exciting and often mutually beneficial relationships with their animal neighbours and the hostile elements of the natural world.”

The God of Growth (James M. Tanner, 1920-2010)

The journal Economics and Human Biology has an obituary (in press) describing the life of James M. Tanner, and his singular contributions to the development of the study of human growth.  In his memorial, Roderick Floud quotes David Barker as saying “Jim was the God” of growth studies.

I had missed news of Tanner’s passing, which occurred in August, and was sad to learn of it. His work has been invaluable to many people, including my own teaching and research, from formulating growth charts to a comparative look at how people grow in different parts of the world. But it’s important to reflect not just on his contributions to science, but also the person behind them. One gets a sense of his compassion from the way he referred to childhood growth as a mirror for “the material and moral condition” of a society (1986: 3). Floud quotes an oft-cited passage by Tanner:


A child’s growth rate reflects, better than any other single index, his state of health and nutrition, and often indeed his psychological situation also. Similarly, the average value of children’s heights and weights reflect accurately the state of a nation’s public health and the average nutritional status of its citizens. . . . Thus a well- designed growth study is a powerful tool with which to monitor the health of a population, or to pinpoint subgroups of a population whose share in economic or social benefits is less than it might be.”

Us, Them, & Non-zero Sumness

I love baseball, having played from Little League through high school. The game taught me many lessons about athletics, but also about life. As a New Englander, I grew up a Red Sox fan, which was sometimes painful (the infamous Bill Buckner game of the 1986 World Series fell on my 12th birthday). However, the 2004 championship was pure elation, and made up for everything. After the Red Sox came back from a 0-3 deficit to beat the Yankees in the ALCS (the semi-finals, for you non-baseball fans), my father, brother, uncles, cousins, and I took photos in front of the television, as if we were documenting history. I even made sure my infant son was in the photos, to prove to him when he got older that he was there. Ridiculous, right?

Killer Ghosts & Broken Hearts: The Mystery of Sudden Unexplained Death in Sleep in Asian Men

One of the strengths of a biocultural perspective in anthropology is its broad approach to understanding human biology and health (Wiley and Allen 2008). Such a framework seems particularly appropriate when looking at the fascinating phenomenon of SUDS (Sudden Unexplained Death During Sleep). Though SUDS first appeared in the medical literature 1917 in the Philippines, where it is referred to as ‘bangungut’ (Guazon 1917), it was largely forgotten until the late 1970s when it regained notoriety as an important cause of mortality among Southeast Asian refugees in the United States, particularly among young men (Baron et al 1983).

A Human Biology of War: The Proximate and the Ultimate

On the surface, it may not be so clear where war, health, and evolution intersect. From the perspective of biological anthropology, many have called for a holistic, transdisciplinary approach to human biology and health which considers the environment as the totality of its evolutionary, ecological, and social components, including social inequality (Little and Haas 1989; Thomas et al. 1989; Wiley 2004).

More than a decade ago, Leatherman and Goodman (1998) suggested that biological anthropologists put more effort toward better understanding what they termed the ‘biology of poverty.’ In this sense, poverty is an ‘environment’ that may induce consistent, but obviously varying, biological responses depending upon local circumstances. Similarly, war can be conceived as a biological environment. At least in the short term from an evolutionary point of view, wartime conditions may be as biologically challenging as some of the classic ecologically extreme environments faced by humans (circumpolar, tropical, high-altitude, desert, etc.) (Clarkin 2010).

Life Is Beautiful

I debated for weeks whether to write about something as personal as the death of my brother Kevin on my (semi)professional blog and to try to explain how this event affected my view of life. Ultimately, I gave myself permission after deciding that it’s a fallacy to think that anyone can seal their personal and professional selves into watertight compartments. The personal side of me draws meaning from what I know of anthropology and evolutionary biology. I agree with the physicist Brian Greene, who once wrote that science isn’t merely about facts and theories; it’s also about the perspective those facts and theories provide. Science widens our horizons. Likewise, my academic side draws inspiration from my personal history, including the people who have been part of my life. I can say unequivocally that I was drawn into anthropology because of the many friends of different ethnicities I’ve had, which made me curious about the biological and cultural diversity of humanity. All of these things are significant events in my life, as is the death of my brother, after whom this website is named.

Kevin (Feb 26, 1977- May 14, 2000) with his son, Daniel

Yesterday marked the tenth anniversary of the passing of my younger brother Kevin, who died after his SUV swerved off the side of a small highway and hit a tree. He was only 23 years old, and left behind a young wife and an infant son. I was 25 and in graduate school at the time, three hundred miles away, and didn’t learn what happened until my father called me at 6 AM the following morning. To this day, any time the phone rings in the early morning or late at night, I am automatically filled with a sense of dread. As my father repeatedly asked me if I was sitting down before telling me what had happened, I immediately knew that someone close to me had died. I didn’t care if I was seated, standing, or on my head; I just wanted to know what happened. After what seemed like an eternity, I relented and told my father that I was in fact sitting down. For the rest of my life, his words will be tattooed in my mind: “Your brother Kevin was in a car accident last night, and he’s no longer with us.”

Hmong children playing on a tractor in Javouhey

The Hmong in French Guiana are a interesting population – refugees from Laos who earn a living by farming and selling their produce in the urban centers of what is essentially a French colony in Amazonia (technically, it’s an ‘overseas department’). I’ve not been back there for a while, but miss it and think about it often. One memory has been on my mind lately: a young couple  (Étienne and Marie*) that my research assistant, KaLy Yang, and I met in the village of Javouhey.

The Sin of Certainty

Screen capture from wikileaks video, Iraq

Lane Wallace wrote a recent article in The Atlantic about bias in journalism, and how it influences the questions that one asks. As journalists are human beings, I think we can reasonably assume that they, like everyone else, have biases. What resonated with me was Wallace’s use of the phrase ‘the sin of certainty,’ coined by the science writer Jonah Lehrer. I think this phrase has great utility and should humble us when we consider how much we don’t know. As an example, chemists have just observed for the first time a new yet-to-be-named element (#117). It took until the late 1990s for physicists to recognize that perhaps up to 95% of the universe is actually comprised of dark matter and dark energy. These are far from trivial matters, yet they have eluded us until now.

The Power of Love

Infant rhesus monkey with terrycloth ‘mother’

As social animals, we need to be around others. Virtually everything we do is social – trade, eating meals, watching sports in stadiums or movies in theaters, religious services, education, the internet, etc. Even war is a social activity. No human being on the planet is completely self-sufficient. Being social is more than utilitarian, however; it is also biologically and psychologically necessary. For example, one of the most severe forms of punishment in prisons is solitary confinement.
