Who’s afraid of a synthetic human?
In the future there will be no more human beings. This is not something we should worry about.
Much of today’s scientific research may enable us eventually to repair the terrible vulnerability to which our present state of evolution has exposed us. It is widely thought inevitable that we will have to face the end of humanity as we know it. We will either have died out altogether, killed off by self-created global warming or disease, or, we may hope, we will have been replaced by our successors.
The Human Fertilisation and Embryology Bill would allow for inter-species embryos that will not only enable medical science to overcome the acute shortage of human eggs for research, but would provide models for the understanding of many disease processes, an essential precursor to the development of effective therapies.
Darwinian evolution has taken millions of years to create human beings; the next phase of evolution, a phase I call “enhancement evolution”, could occur before the end of the century. The result may be the emergence of a new species that will initially live alongside us and eventually may entirely replace humankind.
