In 2012, my wife and I hosted a group of science enthusiasts to a vacation at the C Lazy U dude ranch as part of Science Getaways - vacations with extra bonus science added. While out on our biology hike, we saw vast groves of aspen trees, and learned that they reproduce themselves by sending up runners from their rooots - clones, essentially.

One, though, must've suffered an error during the DNA transcription. Unless there's some evolutionary benefit for an aspen tree to have a bleeding eye in its trunk.

And if that's the case, I don't think I wanna know.
