Introduction to On the Origin of Species

In the introduction to On the Origin of Species, Darwin disarms his critics on several fronts, assuring the reader that (1) he spent much time and reflection on both the theory and the articulation of it; (2) his logic and conclusions have been corroborated by Wallace, and both of their theories published in a reputable journal; (3) the notion of independent creation of "perfectly formed" species is unbelievable; and (4) evidence supporting his theory can be seen even among common, domestic animals.
