The Wall Street Journal last weekend ran an essay by physicist Paul Davies, who has a current book about the Search for Extraterrestrial Intelligence (SETI). The essay, “Is anybody out there” is a short precis of the book.

This paragraph got my attention:

Our bodies contain some genes that have remained little changed in 100 million years. An alien expedition to Earth might have used biotechnology to assist with mineral processing, agriculture or environmental projects. If they modified the genomes of some terrestrial organisms for this purpose, or created their own micro-organisms from scratch, the legacy of this tampering might endure to this day, hidden in the biological record.

A likely early adopter use of biotechnology is people implanting codes of various kinds into the junk DNA of their children. This idea of ancient ET is kind of a love child of that “implanted code” idea and intelligent design — if bacteria were actually products of alien engineering, they might have systems that could not have evolved by incremental processes.

So it’s highly significant that no such systems in bacteria have been identified.
