Gene back to tell you all about cloning. The words 'cloning' and 'genetic engineering' are often used by people as though they mean the same thing. Well, they have an overlapping meaning that becomes clear when we look through history. Genetic engineering, in its broadest definition, means to manipulate a species so that a particular trait is increased in the population. A trait is how an organism looks or acts or what it does.
Brown eyes is a trait.
Flying in circles is a trait. Climbing trees is a trait. The earliest forms of genetic engineering occurred on farms, where most people on earth lived at the time. They managed to do this by selecting seeds from plants that maybe had more fruit production or tastier leaves than other plants of its type. They planted those seeds and grew plants that had more of the favorable traits.
