However, recurrent mutation can not be totally disregarded. • Recurrent mutation tends to maintain a supply of genetic variation for mutation to act upon • Even if selection is tending to eliminate one allele, recurrent mutation tends to maintain its presence in the gene pool. Thus, if the environme ...

History of genetic engineering

Genetic modification caused by human activity has been occurring since around 12,000 BC, when humans first began to domesticate organisms. Genetic engineering as the direct transfer of DNA from one organism to another was first accomplished by Herbert Boyer and Stanley Cohen in 1973. Advances have allowed scientists to manipulate and add genes to a variety of different organism and induce a range of different effects. Since 1976 the technology has been commercialised, with companies producing and selling genetically modified food and medicine.
