Abstract: A simple, natural method of preserving organisms includes sealing biological blood or organisms in a shell filled with resin, curing the resin, and solidifying the shell for a long time to form amber. The biological blood or organisms can be preserved for a long time. Scholars of later generations may research the integrity of the biological blood or organisms of the present days. Otherwise, the biological blood or organisms may be of no researching meaning and purposes due to pollution or oxidation and dehydration. The organisms of the present days may be reconstructed after 100 years by using technologies of that time. Thus, the organisms being extinct due to pollution can be reconstructed. Diversities of organisms on the earth can be maintained. Precious genes of the organisms of the present days can be preserved for thousands years. It contributes greatly to the study of evolution of organisms.
