Strike that, reverse it.
They literally evolved in North America, and when they went to Eurasia across the Bering land bridge they became an invasive species to Eurasia.
For a species to be invasive, it has to be transplanted rapidly by people into an ecosystem. Horses naturally and slowly made their own way to Eurasia and became extinct in the Americas, until they were suddenly brought back to the Americas by the Spanish ... making them invasive.
Lol no it doesn't need to be by people.
invasive species noun
It can be by you know a land bridge like the bering land bridge that was not previously there.
Horses literally evolved in north america and are thus a native species to north america. They are not a native species to Eurasia and are thus an invasive species to eurasia.
At this point I think I'm going to say cheers.
