That means that the play was without fail written after (in Latin, post) 1587.The same inductive mechanism is applied in archaeology, geology and paleontology, by many ways.In this relative dating method, Latin terms ante quem and post quem are usually used to indicate both the oldest and the most recent possible moments when an event occurred or an artifact was left in a stratum.But this method is also useful in many other disciplines.Fortunately, there are other methods available to researchers.All trees of the same species in an area usually have roughly the same pattern of growth.

Scientists first developed absolute dating techniques at the end of the 19th century.Each region has its own unique master sequence since weather patterns are not the same from one area to another.However, the longer bristlecone pine sequence is of little value except for cross-checking the reliability of other dating techniques because logs of this species are rarely found in association with ancient humans. The earliest evidence of writing anywhere in the world only goes back about 5000 years.Paleoanthropologists frequently need chronometric dating systems that can date things that are many thousands or even millions of years older.
