I still claim I am neanderthal.
I really still can't figure out the race thing.
Going back just 20 generations to around 1400 by my calculations I have around 1.5 million ancestors that have contributed their DNA to the amazing creature that is me.
If I go back 30 generations, to around the time of the Norman conquest, I guess I have over 3 billion ancestors.
I only knew six of them but I am guessing all 3 billion were most likely heterosexual. I don't think that makes me a homophobe but I do prefer looking at women,... so maybe.
