A burial site has been found in Cardiff. It dates from the 6th or 7th Century.
The skeletons are all women.
In death, when all genitals have gone, the skeleton retains the truth about the simple fact-it is either male or female.
There is no third way. That's science and hundreds of years after death, the truth of biology is retained in the bone.
Your sex is in your very bones-male or female-that's it. In the end, that's all there is.
Men can pretend to be women but skeletons tell the truth.
The story is on the BBC website.
