The researchers used DNA sequencing from the blood of a male chimpanzee to present the genomes; it is more closely aligned with humans. This event can further explain how feasible animal testing is and explain that the reaction of using animals in testing is only related to DNA sequencing, not the environment (Lovgren 2005). There are absolutely no things about the experiment. Scientists use different animal models and repeated experiments to obtain more confident data which is the best way to test a new product before introducing it
