Question
Ok, until my mind starts wondering again here is my last question to send your way. lol. If a human-being were to be placed naked in space they would be crushed by the vacuum of space and greatly harmed or destroyed by the suns rays if not killed merely by the extreme cold of space? Is there any means within the bounds of the elements people are made of that could make them capable of handling life in space without anything more than a tank of oxygen? Could this evolution ever occur? Also can a human body sustain plant genetics and functions as that their body can produce both oxygen and carbon dioxide so that they might never need to breath external?

Answer
A human in space would not be crushed but would due to the cold temperature and lack of oxygen almost instantly. A tank of oxygen would not help as the person would be frozen.  Since there could be no survival ther could be no evolutionary changes. There is no way an animal can produce oxygen.  It would mean that the animal could carry out photosynthesis.
