How to change a wild plant into a useful crop
The main method, practiced for thousands of years, is to select seeds from plants with desired traits, or breed animals with qualities you like, so those traits are passed on to offspring. After many generations, the selected traits predominate.
Suppose you want to breed a bigger pumpkin. One way is to harness the power of evolution -- a process that can be summarized by the acronym VIST: Variation, Inheritance, Selection, Time. |
