Document Summary
Leads to the perception that the evolution of life could not have happened by itself but it has to be created by something else - predesigned. We have the exact monomers that the polymers are made of. Di erent conclusion - we know that life is made out of polymers composed of those monomers. Argument: life is too complicated to exist the way it did. If you are wrong = not your fault. Tasks: disprove or rule out the simplest model explains all data no or few arbitrary elements testable predictions. Any theory that cannot be tested is not a theory. 50 thousand years - major bombardment > rocks are being replaced all the time. All available oxygen is only available in water. 7: another 50 000 years where we don"t think there was any life on the planet, early life forms ---------------------------------today, archaea --------------------------------> chemoautotrophs. 1. algae important evolutionary single celled algae and algae that live in colonies.
