Mountains have been built and eroded, continents and oceans have moved great distances, and the Earth has fluctuated from being extremely cold and almost completely covered with ice to being very warm and ice-free. These changes typically occur so slowly that they are barely detectable over the span of a human life, yet even at this instant, the Earth's surface is moving and changing. As these changes have occurred, organisms have evolved, and remnants of some have been preserved as fossils. A fossil can be studied to determine what kind of organism it represents, how the organism lived, and how it was preserved. However, by itself a fossil has little meaning unless it is placed within some context.

The timing of many evolutionary and geologic events on Earth has been determined through two complementary lines of evidence: relative dating and absolute numerical or radiometric dating. This evidence makes it clear that life is very old and places a timescale on the pace of evolutionary change, diversification, and extinction. Ammonite fossil. Photo credit Dave Strauss.

It was first used in a newspaper column in which a young man laments that his girlfriend is seeing other people—that they are "fillin' all my dates," as in "the dates on her calendar. At the turn of last century, dating was still a new concept and law enforcement wasn't sure what to make of it—but they were sure something sordid was going on. A young man and woman meeting in public, him buying her food, drink, and gifts: well, it was veritable prostitution in the eyes of authorities, and women could be arrested for it.
