There's no such thing as de-evolution unless you consider evolution has some purposeful direction in the first place. The tomatoes are evolving into the niche that works. Just because there was a plant in the past that occupied that niche doesn't mean the current plants are going backwards - to do so would kind of imply that they know about their current genetic makeup and have decided it's too much effort and isn't working out.
