Final answer:
Potatoes, tomatoes, and tobacco were developed from wild nightshade species through ancient genetic modification. These crops are now crucial to global diets and industries.
Step-by-step explanation:
Potatoes, tomatoes, and tobacco are all plants that have been developed by humans from wild nightshade species. This process of development occurred many thousands of years ago through the method of genetic modification. These vital crops are now widely cultivated and form an important part of diets and industries globally. The nightshade family includes a variety of other plants as well, many of which are rich in alkaloids and have significance in both culinary and medicinal contexts.
