A very nice discussion of what Charles Darwin called “Slave making ants.” I like how the author critiques Darwin for his use of anthropomorphic terminology to describe biological phenomena.


Several weeks ago I came across a curious highway of ants. They were streaming across the leaf litter in a column about a foot wide. The column started under an oak tree, traversed the leaf litter and hiking trail, then ended abruptly about forty feet away in an otherwise unremarkable patch of fallen leaves. Ants traveling away from the tree were carrying white, ant-sized objects in their jaws. Ants moving in the opposite direction were empty-mouthed. At the destination, a few smaller ants milled about, seemingly at ease among the larger ants that I was watching.

I suspected at the time that I was witnessing a raid by a so-called slave-making ant species. My skills as an ant taxonomist are limited and I turned to my colleagues for help. Thanks to James Trager and Ann Fraser, I’ve confirmed my suspicion and been able to tentatively identify the species in…

About kayaerbil

I am a Berkeley educated chemistry Ph.D. who is moving into the area of working on developing appropriate technology for communities that are subjected to socio-economic oppression. The goal is to use simple and effective designs to empower people to live better lives. Currently, I am working with Native Americans on Pine Ridge, the Lakota reservation in South Dakota. I am working with a Native owned and run solar energy company. We are currently working on building a compressed earth block (CEB) house that showcases many of the technologies that the company has developed. The CEB house is made of locally derived resources, earth from the reservation. The blocks are naturally thermally insulating, keeping the house cool in the summer and warm in the winter. Eventually, a solar air heater and photovoltaic panels will be installed into the house to power the home and keep it warm, while preserving the house off the grid. A side project while in Pine Ridge is a solar computer. I hope to learn about blockchain encryption software for building microgrids. In addition, it is an immediate interest of mine to involve local youth in technology education.
