Thanks for the details examples here! So would that mean the"when" for a non-native species to be considered native is on the scale of when it noticeably evolved to adapt to its new environment?

> Invasive species would be like replacing all the keys in your keyboard with the letter H. They turn the machine basically useless. Instead to work with the ecosystem, they destroy it, eliminate most species, and replace it by a much cheaper version. A worse system that is more simple, less stable, and has barely the minimum functionality for us to survive

I guess this would also put humans at the top of the list of invasive species? That sure did sound a lot like what we have done over or history, unfortunately
