The Team in “I”
“We used to think these weird things like corals, lichens, and maybe certain insects, which are amalgamations of symbioses, were the exception in nature. But now we are realizing no, actually, it’s probably everything. Everything is a holobiont.”
Skillings points to the bacteria in our guts and on our skin, even the mitochondria in our cells, as evidence that humans – like coral and cows – are holobionts. From one perspective, a human is a unified organism. From another, we are an ecosystem unto ourselves.
These concepts can impact how we think about human diet and health, a major focus of the first grant, as well as how we understand biological and ecological systems for conservation.
As with a coral reef, the complexity of the project requires different specialists. Skillings has assembled Dr. Ben Allen of Emmanuel College, Dr. Rory Smead of Northeastern University, and Dr. Patrick Forber of Tufts University to aid him in examining how collective entities like ant colonies, corals, or human societies, behave and evolve.
Allen is a mathematician who creates models to predict how cooperative behavior develops in groups. Smead is a philosopher who specializes in game theory and agent-based models derived from economics. Forber is a philosopher of biology who, together with Smead, has studied how spiteful behavior may have evolved in humans to foster group cooperation over time.
“We’ve found there is a really cool, similar set of problems between cooperative behavior in single populations and these multi-species interactions we find in holobionts,” Skillings says.
