I am aware that the conclusions arrived at in this work will be denounced by some as highly irreligious; but he who denounces them is bound to show why it is more irreligious to explain the origin of man as a distinct species by descent from some lower from, through the laws of variation and natural selection, than to explain the birth of the individual through the laws of ordinary reproduction.
Within the period of human history we do not know of a single instance of the transformation of one species into another one. It may be claimed that the theory of descent is lacking, therefore, in the most essential feature that it needs to place the theory on a scientific basis, this must be admitted.
I find the idea of common descent (that all organisms share a common ancestor) fairly convincing, and have no particular reason to doubt it.
The main conclusion arrived at in this work, namely that man is descended from some lowly-organised form, will, I regret to think, be highly distasteful to many persons. But there can hardly be a doubt that we are descended from barbarians.

The birth both of the species and of the individual are equally parts of that grand sequence of events, which our minds refuse to accept as the result of blind chance.
When I view all beings not as special creations, but as the lineal descendants of some few beings which lived long before the first bed of the Cambrian system was deposited, they seem to me to become ennobled.
Obviously I descend from Africa.
The main conclusion here arrived at ... is that man is descended from some less highly organized form.
No one has ever proved that a human being, through his descent from a certain group of people, must of necessity have certain mental characteristics.
