The avocado is a fruit of a different time. The plant hit its evolutionary prime during the beginning of the Cenozoic era when megafauna, including mammoths, horses, gomphotheres and giant ground sloths (some of them weighing more than a UPS truck) roamed across North America, from Oregon to the panhandle of Florida. The fruit attracted these very large animals (megafauna by definition weigh at least 100 pounds) that would then eat it whole, travel far distances and defecate, leaving the seed to grow in a new place. That’s the goal of all botanical fruits, really. Survival and growth via seed dispersal.
