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.
Researchers studied three chickens that appeared to be literally half-male and half-female, and found that nearly every cell in their bodies — from wattle to toe — has an inherent sex identity. 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.
