Genetic Modification From Ancient Practices To Modern Foods

The video discusses genetically modified organisms (GMOs), highlighting unusual examples like glowing pigs and featherless chickens. It explores public concerns about GMOs, especially in food, and explains the historical context of genetic modification through artificial selection. Modern genetic modification techniques are described, including cisgenic and transgenic methods. The video provides examples of GMOs in agriculture and addresses safety concerns, noting that while current GM foods are tested, some exotic pairings remain uncertain.
