Darwins only reference to humans apart from occasional mentions like their hand bones in the first edition of On the Origin of Species was this: Light will be thrown on the origin of man and his history. Darwin believed species originated in one place and then migrated to other places, rather than appearing being created differently in different places. Perhaps there were several early life forms maybe some with different genetic material, not the DNA or RNA we are familiar with. More species occur in populous genera than in the less populous an unusual fact of no significance if one assumes special creation, but understandable under the theory of natural selection. A few naturalists, endowed with much flexibility of mind, and who have already begun to doubt on the immutability of species, may be influenced by this volume; but I look with confidence to the future, to young and rising naturalists, who will be able to view both sides of the question with impartiality.

No two individuals of a population are exactly the same population thinking. Darwin points out that the struggle for existence is easy to overlook or forget about, despite its overwhelming importance: We behold the face of nature bright with gladness, we often see superabundance of food; we do not see, or we forget, that the birds which are idly singing round us mostly live on insects or seeds, and are thus constantly destroying life; or we forget how largely these songsters, or their eggs, or their nestlings, are destroyed by birds and beasts of prey; we do not always bear in mind, that though food may be now superabundant, it is not so at all seasons of each recurring year.
