Famous quotes containing the word species:
“Not only does every animal live at the expense of some other animal or plant, but the very plants are at war.... The individuals of a species are like the crew of a foundered ship, and none but good swimmers have a chance of reaching the land.”
—Thomas Henry Huxley (1825–95)
“Genius detects through the fly, through the caterpillar, through the grub, through the egg, the constant individual; through countless individuals the fixed species; through many species the genus; through all genera the steadfast type; through all the kingdoms of organized life the eternal unity. Nature is a mutable cloud which is always and never the same.”
—Ralph Waldo Emerson (1803–1882)
“The French manner of hunting is gentlemanlike; ours is only for bumpkins and bodies. The poor beasts here are pursued and run down by much greater beasts than themselves; and the true British fox-hunter is most undoubtedly a species appropriated and peculiar to this country, which no other part of the globe produces.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
