Avocado
Archaeological evidence confirms avocado consumption dating to 10,000 BCE in the Tehuacan Valley. The fruit has maintained continuous cultural relevance for twelve millennia, surviving the rise and fall of civilisations whilst steadily expanding its geographic range. Its current popularity represents merely the latest chapter in humanity's longest ongoing fruit relationship. Genetic diversity across hundreds of cultivars ensures continued adaptation to changing climates.
The Joker
The Joker first appeared in Batman #1 in 1940, achieving immediate cultural traction. Eighty-four years of continuous publication and adaptation demonstrate remarkable staying power for a fictional construct. Unlike many Golden Age villains consigned to obscurity, the Joker has gained relevance with each passing decade, suggesting a character whose themes—chaos versus order, sanity versus madness—remain perpetually resonant.
