I believe this story shows several trends for life. The most obvious is that life evolves. When you consider how long life has been on Earth, how many different forms it has been through, and how recently people have appeared, it seems inevitable that people will evolve into other forms of life, however much they may struggle to stay as they are now.

One major force driving evolution has been changes in methods of reproduction. We have seen how the appearance of methods of reproducing without the need for surface water, for example, led both plants and animals into new environments. The domination of mammals today is due to their improved reproduction over reptiles.
With test-tube babies and genetic engineering we will probably see a new wave of evolution. Genetic engineers will be able to control the evolution of people and of other forms of life For the first time in world history, life will be able to control its own evolution.

Another trend we have seen is for cells in plants and animals to live and work more closely together and to become more specialized. Democracy, capitalism and industrialization seem to me to be part of that trend, and (I hope) world government will be another.

Just as dinosaurs were replaced by the more efficient mammals, so it seems likely that organic life will be replaced by more efficient computers, especially in the biologically unwelcoming environment of space.
