This article starts by addressing the extravagant promises and potential dangers associated with genetic engineering. The author argues that while genetic manipulation holds promise, its limitations and potential side effects are often overlooked, advocating for caution and a focus on understanding normal biology. The piece then compares genetic engineering to traditional engineering, particularly in electronics, suggesting plant and animal breeding represent a second stage of engineering where existing traits are assembled. Ultimately, the author questions the possibility of introducing entirely new features and cautions against eugenic applications in humans, advocating for the fixity of kinds based on breeding limitations.
