Mutation

I agree with the origional post. a gene mutation involves a random change in the information within a single gene offspring usually caused by some form of copying error. these mutatoins are rare and only happen once in every thousand cell divisions. Mutation, the theory of evolution states is effectivly saying that the evolution of evrything was a genetic "mistake". How can this be?

ok. fair point. So if the mutations are common surely a mutation still involves a loss of data. Common or not it is according to modern evolution that all complex organs and joints in creatures and plants have evolved by an accumilation of slight changes where each slight change was the result of a genetic mistake.

Ok... so "difference"... however it is still a random accident.
Im still learning! lolHow then can mutation explain the developement of an irriducible mecanism such as the knee joint?The knee joint is irreduceable and cannot evolve as it requires four complex parts (Posterior cruciate ligament, Anterior cruciate ligament, Tibia and fuma) to exist simultaniosly and i complex assembly to be able to praform a useful function.

ok. then how can evolution explain:the process by which two ligaments became crossed at the centre of a pivot joint precisely at the same time at the same time that a space is formed to accomidate them and precisely at the same time that a complex and comparitable rolling motion is formed. I can not see how there can be an intermediate stage.My argumentmay be flaued as i am not an expert yet (im only 15). I would appreciate constructive arguments that would improve my knolage...
