The Search for Life on Earth
June 10, 2009 / Written by: Henry Bortman
The search for life on other worlds could prove that Earth is not the only planet capable of supporting biology. If we found life that was completely different from life on Earth, the discovery would be even more profound because it would mean that there are multiple ways in which living systems can originate and function. But what if a second genesis of life, a type of life unrelated to DNA-based life, is here on Earth? Some scientists believe we should also be searching closer to home.
