    So I was stumbling around on firefox and came upon this fact that made my eyebrows raise.

    "Until a study published in 1905 by Carnegie scientist Nettie Stevens that identified the Y chromosome, gender was thought to be caused by environmental factors, such as passion of sex, nutrition and temperature. These theories had their roots in Aristotle, over 2000 years ago."

    We learn something new every day.

    Additional fact: in many animals, the sex of the fetus IS caused by environmental factors such as temperature. Aristotle mixed us up with crocodiles. :p

    Surprising isn't it? Had no idea my birth city caught up to one of America's historic cities (also called Steel City).
