** {{halliga|I have called this principle, by which each slight variation, if useful, is preserved, by the term Natural Selection, in order to mark its relation to mans power of selection.

Seetõttu võibki tõendeid nende varasemast olemasolust leida üksnes säilinud fossiilsete jäänuste seast [...]

Consequently evidence of their former existence could be found only amongst fossil remains[.]}}
