Phew. I'm so glad I'm not the only one who peppers her everyday language with phrases like "hair whorl direction" or "attached earlobes" or "recessive alleles." But I digress.

Today's Chicago Tribune features an article about a recent scientific survey held in the Windy City called the Molecular Genetic Study of Sexual Orientation, which surveyed the DNA samples 1,000 sets of gay brothers to find genetic commonalities.

"Researchers also have found physical traits that correlate with homosexuality, from the relative size of certain brain areas associated with sexual behavior to seemingly irrelevant characteristics like hair whorl direction and finger-length ratios." There's that phrase again.

A June, 2007 blog entry from Mindhacks.com explores these very same topics and features links to other articles on the subject of the "nurture vs. nature" debate.
