Two sources provide a comprehensive overview of biotechnology and gene editing. The first offers a concise guide covering the history, applications, and ethical implications of these fields, from ancient fermentation techniques to modern CRISPR technology. The second presents a much more detailed and expansive exploration of the same subject, tracing its evolution from prehistoric practices through to current applications and speculative future possibilities, with extensive attention paid to ethical considerations and regulatory frameworks. Both sources emphasize the transformative power of these technologies and the importance of informed public discussion regarding their use.
