Charles Dawin said 'if ever there is found a complex mechanism (something which requires more than 2 or 3 parts to have evolved at excactly the same time for it to work) completly discount my theory'. Scientists have found mechanisms in our bodies which require 40+ parts to have evolved at the same time otherwise it wouldn't work and if parts had appeared on there own then the living thing would have either rejected them or died from sustaining useless parts. I will post the name of the mechanism I am thinking of as soon as I can remember its name.
