There is no way through experiments or observations to falsify the hypothesis of an Intelligent Designer. ID assumes that each molecular machinery is built from scratch, which is not true; existing proteins are often re-used. OID and evolution are both valid hypotheses, but over the years we have found more evidence pointing toward evolution. O ID assumes that systems are irreducibly complex, and that individual components cannot be removed, even though several examples exist of 'irreducibly complex' systems being reduced. en 0 3 $ 35 % ^ 6 18 & * 8 9 44 Indoor Playground with wheelsarrow_forwardNeed help List the four types of evidence that exist in support of evolution.Explain.arrow_forward
