Tomatoes have their origins in a wild plant in the Andes. They have come a long way since.
Admittedly, they contain almost no nutrition but when they are good (rarely, unless home-grown varieties), they are great to eat anyway.
Around a week ago I started a bunch from seeds indoors. Odd varieties, yellow, purple, striped, and mico cherry tomatoes. They are already popping up in the potting mix.
The dried seeds I used are so tiny that I always wonder how they can contain so much, including DNA and all of its instructions. Yeah, animal "seeds" are smaller.
