I never thought I'd hear my mom use the words "genetic drift" in a sentence. She can even distinguish it from "gene flow," which I can't do without looking it up.

My back is killing me. I don't know if it's from the driving, sleeping in a strange bed, or just being generally tense. I had an awful nightmare about being covered w/spiders last night, followed by another one I can't remember, so I must be stressed about something.

Tomorrow is ANZAC Day. I should read something about Gallipoli.
