Humans are native to every continent but one. That said, humans are responsible for all invasive species that have ever been introduced.
Usually in terms of animal or plant species the definition of "native" or not depends on whether humans introduced them to the country or not.
No. No more than other species: canines are believed to have evolved in North America and spread naturally (by migration and territorial/habitat expansion) to the other continents; while felines are believed to have evolved in Eurasia and spread naturally (by migration and territorial/habitat expansion) to the other continents. IIRC humans (at least homo sapiens) are believed to have evolved in Africa and spread naturally in the same manner.
Precisely. Sometimes said introduction was deliberate and sometimes accidental.
Rar I wasn't surprised to see all this! I work in an organisation that prides itself in knowledge on flora and fauna (and dinosaurs 
) and someone asked me a while ago how I could tell trees apart in winter, they didn't know the bark was different.
OK, so I'm not great with winter tree ID myself, and this person didn't specialise in botany, but wow. I understood this stuff as a kid, despite not knowing what to do with it!
It's a shame but in my mind, ignorance in one area just means they're clued up elsewhere. It's how it works I reckon.
