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:
“risk is full: every living thing in
siege: the demand is life, to keep life: the small
white blacklegged egret, how beautiful, quietly stalks and spears
the shallows, darts to shore
to stab—”
—Archie Randolph Ammons (b. 1926)
“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)
