dna

… at least they got it right: if test results I’ve seen are to be believed, a person’s ancestry is very close to random. Which I suspect it is not.

My brother, according to his, has an ancestry entirely different from mine (and no, we didn’t even have a milkman when he was born), while his wife’s is more similar to mine (and no, we are not from the hills of West Virginia).
