Astrobiology Magazine :: Search for Life in the Universe
Are There Aliens Already on Earth?
In his latest book, Life as We Do Not Know It, Ward addresses an issue often avoided by astrobiologists. Although all known life on Earth has a similar DNA-based chemistry, life found on other worlds may not. In chapter 6 of Life as We Do Not Know It, reprinted below, Ward takes this argument one step further. There may, he says, be unfamiliar life forms on Earth, as well. And scientists would be wise to search for them.
Conspiracy theorists will readily tell you that the U.S. military is hiding alien corpses in a secret facility in the Nevada desert. But paleontologist and University of Washington geology professor Peter Ward thinks that scientists should be looking for a different type of alien life on earth: alien microbes. Ward is the author of several popular books about astrobiology, including the controversial Rare Earth, co-authored with Donald Brownlee.

"A golden age has begun for the life sciences, an age in which science and technology will benefit enormously from a fundamental understanding of the full potential of living systems...This is an agenda for inspiring the next generation of planetary explorers and stewards to sustain the NASA vision and mission."
