Assume that you are employed as a developmental biologist atNASA and the first returning mars explorer was found to have asmall organism from mars onboard. The organism had the usualhead-tail axis as well as dorsal-ventral polarity and what appearedto have right-left asymmetry. However upon analysis it was found tobe composed of silicon based compounds and had no DNA, RNA orproteins at all. Discuss reasons why this organism would havesimilar developmental controls to those of earth’s carbon-basedlife and also discuss the opposing view as to why it would not.
