Serena williams also has a lot of muscle and big shoulders. Black women generally have higher testosterone on average.
So the highest standard of evidence is to actually see them "in the flesh" or to see original birth certificates etc.
- who is she? Credentials?
- Can she prove using chemical indicators that this is taking place?
- If she is mainstream then she must have published research that she can cite.
