Heh well they're not technically English. In this case, Greek, but usually Greek or Latin when it comes to scientific nomenclature. All I knew was 'zoa' which you find often in biology since it means 'animal'.

And yeah I'm careful not to call humans the most successful creature. Many animals dominate the planet and simply use us and our habits to their advantage; ants, spiders, mites, rats. If crops disappeared, humanity would pretty much be doomed. If humans disappeared, crops would do pretty darn good! Perhaps that is a form of intelligence, philosophically speaking
