Ordovician%e2%80%93silurian Extinction Event

Famous quotes containing the words extinction and/or event:

    I wish all men to be free. I wish the material prosperity of the already free which I feel sure the extinction of slavery would bring.
    Abraham Lincoln (1809–1865)

    There is not any present moment that is unconnected with some future one. The life of every man is a continued chain of incidents, each link of which hangs upon the former. The transition from cause to effect, from event to event, is often carried on by secret steps, which our foresight cannot divine, and our sagacity is unable to trace. Evil may at some future period bring forth good; and good may bring forth evil, both equally unexpected.
    Joseph Addison (1672–1719)
