The following article contains discussion about two fairly controversial topics: natural selection and poop. Consider yourself warned.
When it comes to eating seeded foods like tomatoes, most people don't think about what happens to those seeds as they pass through the digestive system. As it turns out, they usually go right on through without being damaged...which could explain what's happening at this sewage plant.
This is a tomato plant growing on the side of a poo grinder at a raw sewage plant.
As plants like tomatoes and strawberries evolved, they developed ways to keep their seeds alive even after ingestion.
Way back in the day, when humans were still hunters and gatherers, strawberry plants could be seen growing where latrines used to be. Basically, these plants grew from poop.
In fact, you can still see evidence of this phenomenon today.
Back when train toilets emptied right onto the tracks, tomato plants would pop up in the same locations. This is actually still a problem in England.
So there you have it. When it comes to tomatoes, your poop can play a role in the process of natural selection. The more you know, right?
