Fruits and vegetables have changed a lot since the onset of agriculture 10,000 years ago, as generation after generation of farmers artificially bred crops to select for more desirable traits like size and taste.
But that change can be hard to visualize. So James Kennedy, a chemistry teacher in Australia, created some terrific infographics to show just how drastic the evolution has been. This one, for instance, shows how corn has changed in the last 9,000 years — from a wild grass in the early Americas known as teosinte to the plump ears of corn we know today…
Mind you, not all attempts at selective breeding turn out so well. As Sarah Yager recently wrote at The Atlantic, apple-growers in the United States during the 20th century tried to breed Red Delicious apples to be as bright and shiny as possible and stay on shelves for as long as possible without noticeable bruising. The result? “As genes for beauty were favored over those for taste, the skins grew tough and bitter around mushy, sugar-soaked flesh.” Nowadays, as storage and transport have become more advanced, tastier apple varieties like the Honeycrisp or Gala are surpassing the Red Delicious.
The article gives watermelon and peaches the same treatment and ends with links to FDA definitions that range from selective breeding to the difference between cisgenesis and transgenesis. I’ll launch into that some other time – once again – trying to explain to the Vegan Left that science doesn’t define DNA as good or evil.
