Biology is the science concerned with the study of life.

Famous quotes containing the word life:
“One should not confuse the craving for life with endorsement of it.”
—Elias Canetti (b. 1905)
“There is something servile in the habit of seeking after a law which we may obey. We may study the laws of matter at and for our convenience, but a successful life knows no law.”
—Henry David Thoreau (18171862)
“Coming to terms with the rhythms of womens lives means coming to terms with life itself, accepting the imperatives of the body rather than the imperatives of an artificial, man-made, perhaps transcendentally beautiful civilization. Emphasis on the male work-rhythm is an emphasis on infinite possibilities; emphasis on the female rhythms is an emphasis on a defined pattern, on limitation.”
—Margaret Mead (19011978)
