Alexis Rockman. Manifest Destiny, 2004, oil on wood, 96 x 288 in.
Image 1. As an interesting aside, artists have arguably been the ones to most seriously consider the evolution in and around houses. Alexis Rockman for one has imagined the forms of vertebrates in the urban, domestic future. He imagines the diversification that will occur in cities, a radiation of wild (and in his work, apocalyptic) forms.
Once we have predictions, we could simply wait and see–across months, years and centuries–whether the lineages that evolve in the future meet our expectations but there is also another approach. We can consider the evolution that has already occurred in our homes. The first human homes were built more than 100,000 years ago (For more on the history of homes, see the book by Jerry Moore, The Prehistory of Home; Jerry, like Jason Munshi-South and Michelle Trautwein, is also involved in our group). That is plenty of time for us to see evolution in many of the species that live with us, evolution in addition to that due to factors we already know to have had an effect, such as pesticides and antibiotics. How different are the species living in our modern homes from those of our first homes, or the nests of hominids? No one appears to have ever studied the species living in the closest analogues to the antecedents of our homes, the nests of chimps and gorillas. No one has ever sampled the species living with hunter-gatherers either. No one has compared the species found in houses of different parts of the world. It is high time to build a ship of sorts to sail along these shores and into the unknown, but before we do, we need a framework, we need ideas of what we most need to understand, we need hypotheses.
The Sloan Foundation has generously provided the support for our upcoming meeting of the minds, a gathering that will include artists, cultural anthropologists, archaeologists, evolutionary biologists, microbiologists, a psychologist, ecologists, experts in urban and household design, epidemiologists and even those strange bug-sucking beasts, the entomologists. It is a super team of people from fields that would almost never normally interact, people who might fight or disagree (though we hope not, and even if it happens it seems likely to be passive aggressive, not aggressive–we are academics after all), but will almost certainly bring to bear new insights on the questions at hand.
Once we have reframed the study of indoor evolution, where will our own H.M.S. Beagle sail? Into your bedroom, we hope. That is the good news. We do not need to build or buy a boat to explore the evolution in our homes, we just need you to walk around your house and do experiments, sample or in other ways help us to see the wild diversity that has already emerged where we live. Where Darwin had the Beagle, we have you. For that we are grateful. The actual Beagle was a stinking (the dead finches were the least of the problem), leaking mess of a boat anyway.
But we don’t want to just wait until the fun stuff–coming up with the wild ideas–is done. We’d like your help now. We want to know what you would like to understand about the evolution of the homes (and/or cities) you are living in. We invite you to post your wild questions and ideas and, in doing so, think about how to study the species around us.
For our part, as we meet, we will make each part of our meeting as public as possible so that we might have a think tank of twenty one people in Durham, North Carolina, augmented with the ideas from thousands of other people around the world. But be prepared, if you get involved we may test your new idea and, in doing so, recruit you to go into your home and help us to see the evolution all around us, the evolution that we wake up to every day–as predictable as bird song or the sun’s rise–but mostly ignore, because whether or not we study the evolution in your bathroom or on your face, it is happening. Some versions of genes are being favored, others are becoming more rare, all because of the ways we live, the ways we live and the ways the species alongside us live, breed or die.
Note: As we get closer to our meeting, we will tell you more about the members of our group, both through stories of their work and interviews about what they have done. This meeting is being organized by Craig McClain, Kerry Kinney, Jonathan Eisen and me, Rob Dunn. You can find a brief bio of everyone else below (note, I’m editing this right now, so if you don’t see 20 people that is why).
Who is the Group of 20? Rachel Adams has studied the dispersal of fungal spores into homes. Holly Bik is an innovator in techniques to use genetic approaches to see what is otherwise invisible, particularly when those small beasts are multicellular. Ashley Bateman is a microbial ecologist who recently discovered that the bumps that occur during roller derby can transfer bacteria from one person to another. Noah Fierer is a microbial ecologist who has studied everything from armpits to Central Park, but all from the perspective of bacteria. John Hawks is a paleoanthropologist with an eye toward the big story of human evolution, or maybe both eyes. He is that good. Sarah Hird is an evolutionary biologist who has worked on everything from the love lives of chipmunks to the ancient divergences of carnivorous plants. David Hughes studies the ways in which parasites take over the minds and lives of their hosts, though he can’t rule out that that is just what his parasites are telling him to study. Stephen Kembel studies diversity and diversification, whether in hospital rooms or grasslands. Kembel has recently shown that hospital rooms with their windows open are less dominated by pathogens than those with their windows closed. Sergios Kolokotronis uses molecular tools to reveal stories about our everyday life that we had, in our busy days, missed, whether that be the identity of the fish at the supermarket or, most recently, the evolution of bedbugs. Gabriel Levy is a religious scholar working on a new book on Judaic Technologies of the World (When I said it was a broad group, I meant it). Laura Martin studies how people perceive, study and manage the environment (be it wilderness or basement). Her field work has focused on vertebrates in wetlands which sneak around and influence the life in and around our homes more than one might think. Raul Medina studies the process by which new lineages of insects evolve by switching from one host to another, whether that host is a plant or the body of another insect. Could parasites be diverging within our homes as they switch to new hosts? Maybe. Corrie Moreau studies the evolution and life history of societies (typically ants) and the species that live with them. Corrie is the only member of our group ever (to my knowledge) featured in a cartoon. Jason Munshi-South studies the evolution and ecology of vertebrates in New York Cities. Recently, he has spent some time in the sewers of New York. Rumor has it, he was looking for mutant, super rats. Rumors though can be wrong. Samuel Crane studies the evolution of species in response to human alteration of the environment. He has revealed secrets about the evolution of important agricultural weevils that even the weevils didn’t know. Will Wilson has written the book on the climates humans have constructed in cities, literally. Juan Ugalde studies the evolution and function of particular skillsets of microbes. We hope he can help us figure out not just the evolutionary stories of microbes in homes, but also what they do once there. Michelle Trautwein studies the evolution of flies (which are very, very diverse in homes) and the diversity of arthropods in homes more generally. Michelle found more than a hundred species of arthropods in my home. I am too nice a guy to say how many were found in Michelle’s (but it was more, just for the record). Martin Taeubel has worked on many aspects of indoor microbiology, specifically focused how elements of house construction influence microbe composition and how microbe composition influences health and well-being. He has also named a new species of Staphylococcus from a Himalayan goat. Jeffrey Siegel is a civil engineer, interested in indoor contaminants but also the links between outside and inside environments more generally. He has worked actively to understand how to build houses so as to make them more healthy. Laura Popova is an anthropologist interested in the ecology, culture, history and socio-politics of pastoral societies. A key element of understanding the species in our homes is understanding how those species relate to the ways we live, have lived and could live. Laura considers these ways. Clare Palmer studies the ethics of our relationship to other species. Her most recent book is Animal Ethics in Context. Sergey Nuzhidin is an evolutionary geneticist. His work has focused on model organisms (fruitflies and the like) but increasingly he has become interested in the species living alongside him in the lab and just outside. Gwynne Mhuireach is interested in the influence of home design on microbial communities and human health.
