Living Fossils
Living fossil is an informal term for any living species (or clade) of organism which appears to be the same as a species otherwise only known from fossils and which has no close living relatives. These species have all survived major extinction events, and generally retain low taxonomic diversities. A species which successfully radiates (forming many new species after a possible genetic bottleneck) has become too successful to be considered a "living fossil".
Famous quotes containing the words living and/or fossils:
“See! those fiendish lineaments graven on the darkness, the writhed lip of scorn, the mockery of that living eye, the pointed finger, touching the sore place in your heart! Do you remember any act of enormous folly, at which you would blush, even in the remotest cavern of the earth? Then recognize your Shame.”
—Nathaniel Hawthorne (1804–1864)
“In early times, before the floods swept across the world, there was life, albeit odd, as one can see from the fossils of mammoth bones, and there was the regime of Prince Metternich.”
—Franz Grillparzer (1791–1872)
