The fruits we eat today, they weren't the same before a period of time. After human started severely cultivating them, these fruits changed dramatically.

•Watermelon:
If you talk about huge, juicy watermelons, they used to look smaller than apples! Also they tasted bitter, not sweet at all. Over time, humans have bred watermelons to have a red, fleshy interior which is actually the placenta like the ones seen here.

•Banana:
In the 1950s, various fungal plagues (most notably Panama disease) devastated banana crops. By the 1960s, the Gros Michel was effectively extinct, in terms of large scale growing and selling. Enter: the Cavendish, a banana cultivar resistant to the fungal plague. It's the banana that we eat today.

•Carrot:
(Daucus carota subsp. sativus) is a root vegetable, usually orange in color, though purple, black, red, white, and yellow cultivars exist. They are a domesticated form of the wild carrot, Daucus carota, native to Europe and Southwestern Asia.

•Corn:
For a long time, scientists couldn't figure out where domesticated corn originally came from — it doesn't look like anything that grows in the wild. It took serious sleuthing by geneticists, botanists, and archaeologists to figure out that maize split off from teosinte grass some 9,000 years ago.

•Tomato:
Early incarnations of the plant had tiny green or yellow fruit. It was used in cooking by the Aztecs, and later explorers brought the tomato back to Spain and Italy.

•Cabbage:
Cabbages and kale presumably originated in Western Europe; cauliflower and broccoli in the Mediterranean region. Cabbages and kale were the first of the cole crops to be domesticated, probably about 2,000 years ago.
