Don't worry, they won't bite people, nor any animals. However, this just gave me an idea... What would happen, if someone created a genetically modified plant - Which would be intelligent too, will have ferocious teeth, and maybe able to uproot itself to a new location at will. Wouldn't that be something??? With recent advancements in the field of genetics, this isn't all that farfetched today... Would be entirely possible by the year 2030 for sure.
