I started out in anthropology, so to me how society works, how people put themselves together and make things work, has always been a big interest.
Ever since I was a kid, I've had an enormous interest in the sciences - everything from quantum physics to anthropology.
Here I was into astronomy, and here into anthropology, and there I go into geology. It was much more fun to be able to research and write about whatever I wanted to.
I never got any training in how to write novels as an English major at Oberlin, but I got some great training for writing novels from anthropology and from Margaret Mead.
I was in an interdisciplinary major - which was a new thing then - which was psychology, sociology, anthropology, and biology, which is really sort of the study of the human being.
Once anthropology and geology had opened up the pre-recordkeeping darkness of humanity's long, slow, sustained infancy as suitable grounds for speculation, writers began trying to imagine human existence as it must have been with only stone-age technology.
I have a B.S. in Biology from MIT, an M.Sc. in Human Biology and a Ph.D. in Biological Anthropology from Oxford University, and an M.D. from Harvard Medical School. I never intended for so many degrees, but I enjoyed getting them all.
Telling everyone I wanted to go into forensic anthropology was my form of rebellion.
Maybe if I'd studied writing instead of anthropology, I'd be more sensible. You know - pick a genre, follow the rules, stay in the box - but let's face it. Sensible people don't major in anthropology.
