Abstract: In the biological world, genetic and variation phenomenon is naturally prevalent. The species reproduction and evolution are dependent on both genetic and variation. Likewise, technology is also made a feature of genetic property. Based on the law governing biological genetic and variation, product development can be obtained quickly through the genetic and variation characteristics of the current technology. Combing the analysis on genetics, biology, and evolution theory, the technological genetic property of new product development is looked into and the technology evolution pattern in the new product development as well as the route of new product development are discussed.
