Scientific paper

Within the context of how to search for life in the Solar System, we discuss the need to consider universal evolutionary biomarkers, in addition to those of biochemical nature that have already been selected for in the biology experiments of the old Viking and future Beagle-2 landers. For the wider problem of the evolution of intelligent behavior on other worlds (the SETI program), the type of experiments suggested below aim at establishing a direct connection between Solar System exploration and the first steps along the pathway toward the evolution of intelligent behavior. The two leading sites for the implementation of the proposed first whole-cell experiments would be, firstly, Europa after the Europa-Orbiter mission (Phillips and Chyba, 2001), either on the ice-crust (Greenberg et al., 2000), or in the ocean itself by means of a submersible (Horvath et al., 1997); secondly, such experiments could be implemented once isolated liquid water oases are identified in the Martian substratum.
