Perhaps the avocado pit will go the way of the lestodon. But just as avocados adapted for megafauna, so do we adapt avocados to our needs. The maligned avocado pit is what’s called an “ evolutionary anachronism.” No sloth on today’s earth is capable of pooping out such a large seed, yet the pit persists. Though humans weren’t swallowing the fruits whole, they did plant them widely over South and Central America, probably giving themselves avocado hand all along the way.
While human hunters likely contributed to the end of the megafauna, both giant sloths and people had something in common: a love for luscious avocado. The avocado might have only survived in a valley or two as a small, obscure fruit, if a new propagator hadn’t come along: us. Without large creatures around, seeds simply fell to the ground and rotted. (Some survived, such as the much-bigger-than-you-think moose.) Accordingly, the ranges of many of the plants they ate also shrank. Near the end of the Pleistocene Ice Age, a fluctuating climate wiped out many megafauna. Many big-seeded plants across the Americas, such as osage oranges and honeylocusts, similarly were propagated by megafauna. These giant sloths had no problem spreading avocado pits. It was a good deal all around, and it likely resulted in avocados as we know them: fatty and large-pitted, all the better to attract huge sloths. When pooped out, far from their parent trees, the seeds could sprout and grow without competition for water and sunlight. These enormous creatures’ digestive systems could process large seeds, and avocados benefited. Giant sloths, along with megafauna like gomphotheres and glyptodons, feasted on whole avocados and spread their seeds over South America. But they occasionally ate a more nutritious treat: the early avocado. Their diet consisted of grass and foliage. Lestodons were much, much larger than your typical sloth they put the “mega” in “megafauna.” Weighing from two to four tons, lestodons, along with other “ground sloths,” roamed grassy plains in South America. But these Cenozoic-era creatures were sloths, the direct ancestors of the ones still around today. Lestodons might sound like toothy, scaly dinosaurs. That’s because lestodons could eat avocado pits, which is the only reason we have avocados at all. But if we all had digestive systems like the ancient, extinct lestodon, we wouldn’t have this pesky problem.
Available only in a few British supermarkets, they supposedly prevent “avocado hand.” This surprisingly common injury, from knife slippage while prying out avocado seeds, can cause serious nerve and tendon damage. Last December, social media buzzed with a new food innovation: seedless avocados.
