The Alternative History Thread

I'm reminded of the 90's TV series Sliders where in some parallel worlds the Cro-magnons had evolved alongside normal humans, The Kromags

 

And in the world of GW....
I had a book by them (or maybe Citadel) (lent to a mate and never got it back) which gave the history of the greenskin races. Originally the only greenskins where goblins and snotlings. They had the brains and evolved the orcs to do all the muscle work. But being bigger and stronger the orcs took over and now the gobs and snots are subservient to them. What if orcs where never developed.....???

 

What if the Dutch colonised New Holland ahead of the British. Where would Australia be now...?

 

Typical TV show getting the science wrong.
