" richly financed experiments were, at the insistence of Dorian Purcell, focused intensely on archaea, the third domain of animal life. The first domain is eukaryotes, which includes human beings and all other higher organisms. The second domain is bacteria. Microscopic archaea, which lack a nucleus, were long thought to be a kind of bacteria. But they have unique properties, not least of which is the ability to effectuate horizontal gene transfer. Parents pass their genes vertically to their offspring. Archaea pass genetic material horizontally, from one species to another. Their mysterious role in the development of life on Earth is only beginning to be understood, and perhaps it is madness to seek to harness them for the purpose of improving the human genome and extending the human life span.
