Yale researchers have shown that the origin and evolution of the placenta and uterus in mammals is associated with evolutionary changes in a single regulatory protein, according to a report in Proceedings of the National Academy of Sciences. "Many past studies have shown that genes are regulated and altered by changes within their own structures. This is the first work suggesting that the evolution of transcription factors — separate regulatory proteins — may play an active role in the origin and evolution of structural innovations like the placenta and uterus," said senior author Gunter Wagner, the Alison Richard Professor of...
