Genetic engineering has evolved significantly from the ancient practice of selective breeding, which humans have used for centuries to develop specific traits in animals like dogs and horses. This method allowed for the enhancement of desirable characteristics through careful selection. Hybridization, a form of selective breeding, combines diverse organisms to create hybrids that exhibit the strengths of both parent species. This historical context sets the stage for understanding the advanced genetic engineering techniques employed today to improve traits in various organisms.
