Some reject the Darwinism by saying that it is "only a theory". This argument has two weaknesses. Firstly, it ignores the fact that Darwin affirmed two things: that the modern species go down from ancestral forms and that the natural selection is the principal mechanism of the evolution. The evolution is attested by historical facts. To take no account of the data showing that the Mammals go down from the Reptiles simply because nobody could observe the transition is equivalent to denying the French Revolution under pretexte that none among us was witness of it.
