Michael Andrews reading, "The Life That Lives on Man"

1. summarize key points:
Amazing facts about parasites living on our skin. We start out with a history of human awareness and thought concerning these parasites, and how the field of parasitology developed in tandem with medical science.

We move onto the landscape of our skin - the dry, flaky deserts of our arms with the occasional hairs, and the oily, densely packed landscape of our scalp. Sweat glands, hair follicles, sweat and salt everywhere. What a place for a bacteria to live!


2. Develop an argument about compelling points:
He mixes ecology with the study of parasites, engaging different levels of scale and redefining the original meaning of what it means to study ecology. We use models of our understanding of microbes and scale to even be able to think about the life living on our skin!

Andrews also examines the idea of what it means to be a human, and how human agency is in part a product of symbiotic interactions with microbes and mites, and also our very biology (i.e. salty epidermis) is a product of interactions with various biotic stresses. In other words, our agency is in part a product of the concatenations of many other agencies.



3. Words I learned today:
scurf: a clump of skin scales
squames: tough, horny flakes on the surface of our skin
