First, the class would would investigate genetic editing history and determine the differences between gene editing and artificial selection. Thousands of years ago, humans were selectively breeding wolves and created a new species: the domesticated dog. In the 1980s, scientists translocated genes from one species to another to create vegetables with longer shelf lives and pesticide resistant crops. Recently, biologists started directly changing base-pairs on the genome itself with tools such as CRISPR. Which of these are actually considered gene editing?
Next, the class would study the current debates behind GMOs. Some genetically modified (GM) crops increase food production, which would feed an ever-growing human population. However, many GM crops are not being fully tested for long-term human health and environmental risks. Right now, many of our most common crops are genetically modified, including rice and corn. Is it ethical to modify these crops? Should we do the same with salmon? Chimpanzees?
