The present invention provides manufacturing processes for biological replication of undifferentiated plant and animal cells and tissue in a weightless condition, including those systems used in current stem cell research and development and use of undifferentiated parenchyma in plants. The present invention further provides methods for adapting plants and animals to survive outside their native environments. In particular, undifferentiated cells from plants or animals are replicated under weightless conditions in which cell replication or proliferation is accelerated and sustained. Under such conditions, the undifferentiated cells can be “forced” to express sets of genes useful for survival in particular environmental conditions. In this manner, cells surviving prolonged exposure to specific environmental conditions can be selected for and cultivated to produce an organism adapted to that particular environment in an accelerated manner. Methods of identifying specific genes associated with adaptation of a plant or animal to a specific environment are also disclosed.
