Bacteria have flourished on the earth for over three billion years. They were the first life forms on the planet.
The first oncogene was discovered in 1970 and was termed SRC (pronounced "SARK").
The term bacteria was devised in the 19th century by German biologist Ferdinand Cohn. He based it on the Greek word "bakterion" meaning a small rod or staff. Cohn is considered to be the father of modern bacteriology.
