Science has taken another small step towards determining the origin of life:

September 2, 2008Scientists Develop New Computational Method To Investigate Origin Of Life
Scientists at Penn State have developed a new computational method that they say will help them to understand how life began on Earth. The team's method has the potential to trace the evolutionary histories of proteins all the way back to either cells or viruses, thus settling the debate once and for all over which of these life forms came first...Scientists map out the evolutionary histories of organisms by comparing their genetic and/or protein sequences. Those organisms that are closely related and share a recent common ancestor have greater degrees of similarity among their sequences...

The baobab tree represents one of the most ancient species of life on the
planet. Scientists have investigated ancient and highly divergent proteins,
called retroelements, whose evolutionary histories hold keys to uncovering
the origins of life.
