Edgar Rice Burroughs,
The Gods of Mars
“ Thus as time went on, all Barsoom was covered with these imprisoned creatures. For countless ages they lived their long lives within their hard shells, hopping and skipping about the broad planet; falling into rivers, lakes, and seas, to be still further spread about the surface of the new world. “Countless billions died before the first black man broke through his prison walls into the light of day. Prompted by curiosity, he broke open other shells and the peopling of Barsoom commenced. ”
