Introduction
The relation between humans and genetic manipulation is older than we think. Humans have been manipulating the transfer of genetic information between organisms for over 10.000 years. The first experiences were with cultivation of grains and domestication of animals. The facilities that these methods bring in order to keep having the necessary stuff for our survival make the humans improve their techniques. Now, with the advances of science, we have some sophisticated ways to make easier get the most wanted kinds of livestock and plants. Selective breeding and transgenesis are examples of popular (and successful) processesTransgenesis and Selective Breeding Essay involving genetic manipulation in the current context.
