Biology is the science concerned with the study of life.

Famous quotes containing the word life:

    There are more truths in twenty-four hours of a man’s life than in all the philosophies.
    Raoul Vaneigem (b. 1934)

    All my life I’ve felt like somebody’s wife, or somebody’s mother or somebody’s daughter. Even all the time we were together, I never knew who I was. And that’s why I had to go away. And in California, I think I found myself.
    Robert Benton (b. 1932)

    We have got to know what both life and death are, before we can begin to live after our own fashion. Let us be learning our a-b- c’s as soon as possible.
    Henry David Thoreau (1817–1862)
