Extract

“ The condor lays a couple of eggs and the ostrich a score, and yet in the same country the condor may be the more numerous of the two ; the Fulmar petrel lays but one egg, yet it is believed to be the most numerous bird in the world. One fly deposits hundreds of eggs, and another, like the hippobosca, a single one ; but this difference does not determine how many individuals of the two species can be supported in a district.”—Charles Darwin, The Origin of Species.
