In 1859 Charles Darwin published the first edition of the origin of the species which amongst other things. In 1865 Gregor Mendel publicized his own discoveries on which he breed peas which became the foundation of modern genetics.1910 T.H Morgan demonstrated that chromosomes are the concrete entities which carry the genes. These scientist all did different experiments to modified animals. In 2006 a pig was engineered to produce omega acids through roundworm genes.
One of the biggest breakthroughs on the path to genetic engineering was the discovery of the structure of DNA in 1963 by an American biologist James Watson that discovered enzymes and they are special chemicals that can recognize and cut DNA at a specific development.
