Przewalski distribution, that surprising? (Patreon)

I've spotted folks be surprised at just how 'widespread' przewalski horses are currently by this map alone. But consider that there are many more zoos (outside Eurasia too) that host these horses than what I have depicted here. The red dots represent Reintroduced ranges in conservations, free roaming herds and active breeding facilities that I was able to sniff out.
The gradient displays the historic range of this equine. Dark red is of course what most people agree on what the range used to be. Pale is what it most definitely used to be, given that Przewalski horses originate from northern kazakhstan.
Some other maps include Europe, but that would not be possible...I believe, because przewalskis are a recent divergence some 6000 b.c. on a continent that had many different 'types' of horses, from iberian ones to siberian ones.
Sure yes there were wild horses across all of eurasia! But Przewalskis were only one of many, they were not 'the' wild horse.
