Really? Genomics confirms that the tomato is a fruit, not a vegetable? No, probably just Gisela's lame attempt at humor. There are a lot of good reasons for genomic research, comparing one genome to another, but it doesn't seem that this science writer touched on any of them. Genomic research wasn't needed to identify the domestic tomato's closest wild ancestor; yes, it confirmed it, but it was already known, well known. And yes, tomato is pretty close to potato too, but that was already so well known that tomato has been transferred back into the genus Solanum, discarding its colorful genus Lycopersicon ("edible wolf peach", maybe distinguishing it from other toxic red-fruited nightshades), a triumph for Linnaeus who put it there in the first place. So what did we learn from this fluffy bit of science news? Not much.
