All "native" species to any local ecosystem were once invasive. Whether something is invasive or native all depends on what date you pick. To 1600s America, the British were "invasive"; to 1900s America, British-derived peoples are "native". To 1600AD, humans were "native"; to 20,000 BC, ALL humans were "invasive".
So if you want to make a statement like that, please date your context, like, say, the arrival of the first humans...so that eventually we can uncover evidence that even THOSE humans weren't the first. ;-)
I love science.
Almost all of the organisms currently living on Easter Island are invasive species that have been introduced, Wynne said.Mr. Wynne:
