The story of human evolution is long and complicated, but the simple truth is - you’re only here because your ancestors got lucky. Plus, we wind the clock back to the very start of human life, and discover how new research is pushing back the frontiers of human embryology. Plus a suitably festive gene of the month. This is the Naked Genetics podcast for December 2016 with me, Dr Kat Arney, brought to you in association with The Genetics Society, online at genetics.org.uk.

Hi Kat, Don't want to spoil the party but Factor IX deficiency/Haemophilia B/Christmas disease has been called the last name for a lot longer than 1993. In studying medicine in the 1970's I used Muir's Textbook of Pathology, 10th ed, publ1976. On p 501 Christmas disease is specifically mentioned as factor IX deficiency. A quick web search shows Stephen Christmas was diagnosed in 1952 and died in 1993 (Wikipedia). Your description of the disease sounded as if the name only came after his death.
