The Gomphotheres and the Avocado
Most plants bear fruit so that animals can eat them and then disperse their seeds. Avocados, and a few other fruits, are too large (or rather have seeds too large) to be eaten and be dispersed by any animals that are extant (currently in existence). These large seeded fruits, that are found throughout the Americas, evolved along with the large mammals of the Pleistocene epoch (the “Pleistocene Megafauna”), like Gomphotheres, other proboscideans, and Giant Ground Sloths. These animals went extinct around 10,000 years ago, and the Avocados lost their chief dispersers. Many plants went extinct along with the megafauna, but some, like avocados, found new dispersers (like humans and slightly smaller mammals). The geographic range of many of the fruits that survived decreased greatly, but they managed to hold on.

Avocados r gross but at least they r pretty.
Humans are opinionated but at least they are omnivores.
