TIL that horses went extinct in North America about 10,000 years ago. They were then reintroduced to the continent by the Spanish as early as the 1550s. (www.pbs.org)

Lol no it doesn't need to be by people.

invasive species noun

Any species that has been introduced to an environment where it is not native, and that has since become a nuisance through rapid spread and increase in numbers, often to the detriment of native species.

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.
