Genetic modification
Humans withdraw considerably valuable genes from bacteria, plants, animals, or fungi and insert them into domesticated plants and animals. With biotechnological invention, humans can select and control traits, expression, and cell lineage via exchange of genes. New traits are generating, resulting in an increase of macromutation. The exchange of exogenous genes has resulted in a rise of antibiotic resistance. Consequently, if the domesticated traits release into the wild, the traits will spread rapidly and produce evolutionary changes (Palumbi, 2001).


·         Insecticide proteins, herbicide tolerance, or vitamins into crop plants

·         Growth hormones into farmed salmon or livestock
