Fascinating fact. Begs the question what pollinated agriculture (squash, tomatoes, peppers, berries etc) prior to the introduction of the honeybee and the equally fascinating answer is that there were many species but all of them were SOLITARY and NON-HIVE DWELLING!
I wonder if it would be possible to experiment a bit - ban honeybee hives in a 10 mile square radius, or perhaps in that area that bans all radio transmitters. See what happens.
That depends on how you draw the line. Most would consider buffalo[0] to be native to North America, but they arrived less than 200000 years ago. If you go far enough back, no life is native to anywhere except wherever abiogenesis occurred.
