THE AVOCADO IN YOUR KITCHEN SHOULDN’T EXIST

The Hass avocado in your kitchen is a biological impossibility. Its seed is too large for any living animal to swallow it whole. Yet seed dispersal by animals is how the species evolved to reproduce, like many others. The avocado tree’s survival strategy was designed for creatures that have been dead for almost 13,000 years.

The avocado co-evolved with Pleistocene megafauna. Giant ground sloths. Gomphotheres, which were elephant relatives. Toxodons, rhino-like mammals.¹ These animals could swallow the fruit whole, walk miles, and deposit the intact seed in nutrient-rich dung (animal poo). The seed was designed to survive digestive tracts. The flesh was designed to be irresistible. The relationship was mutual.

Then the megafauna disappeared. Climate shift. Human hunting. A combination of both… By 10,000 years ago, the large animals were gone.² The avocado had no way to reproduce at scale. No animal left could swallow the pit and move it. Populations would have contracted. Isolated groves. The occasional flood carrying a fallen fruit downstream. A slow but quiet extinction.

I sat with that for a minute when I found it. But then I really started pondering for a bit…
