Kanan writes: From the article, "A study of sexually scrambled chickens suggests that sex in birds is determined in a radically different way from that in mammals.

This cell-by-cell sex orientation contrasts sharply with the situation in mammals, in which organism-wide sex identity is established through hormones." Check out the picture's on at the BBC's story.
