For decades, people thought that avocados with their huge seeds were spread across Central and South America by giant sloths that went extinct 10,000 years ago. That made senes, because avocados have very large pits, and it would take a huge animal to ingest them and poop out intact pits to grow further away from the parent tree. But it turns out there is no study, no data, and no evidence to support that. It was just an idea someone had that seemed to make sense. We reported it, and so did Sci Show. But now Hank Green explains where that “fact” came from and why it ain’t necessarily so. It turns out that avocados didn’t always have such huge seeds, and the reason they do may have more to do with human avocado fans than with giant sloths. Score one for mythbusting, and an example why there is always a need for fact checking and further research.
