Instead of venom, Braconid wasps inject their victims with a virus that suppresses the victim's immune system and allows the wasp's parasitic larvae to grow within the victim. Scientists found that this virus is unlike any other virus on Earth. It is over 100 million years old and apparently assimilated itself into the very DNA of the wasp.
And the Vikings beat the Polynesians by another 200+ years and "discovered" America in the 1100's.
