      Hi, Ez3t1524, you are absolutely right. As human, we are very similar to each other. Genetically, we are all 99.9 percent the same. That little difference defines an individual, which is used in finding the suspects in crimes. Because all creatures started from the same orgnaism, we are very related to other animals. For example, there is 95% to 98% similarity between humans and apes from DNA point of view.
