Observation: succession of fossils

Relative relationship is used to rearrange geological occasions, and the rocks they depart behind, in a sequence. The technique of studying the order is identified as stratigraphy (layers of rock are referred to as strata). For instance, primarily based on the primate fossil report, scientists know that residing primates advanced from fossil primates and that this evolutionary history took tens of millions of years. By evaluating fossils of different primate species, scientists can study how features changed and the way primates developed by way of time. However, the age of each fossil primate must be decided so that fossils of the identical age found in several elements of the world and fossils of various ages can be compared. Some young-earth creationists have also claimed that scientists cannot know with any certainty what occurred hundreds of thousands of years ago — one would want a “time machine” for this.

Radiometric relationship and certain other approaches are used to supply absolute chronologies when it comes to years earlier than the present. The two approaches are often complementary, as when a sequence of occurrences in a single context could be correlated with an absolute chronology elsewhere. For instance, if the measured abundance of 14C and 14N in a bone are equal, one half-life has passed and the bone is 5,730 years old (an quantity equal to the half-life of 14C). If there is three times less 14C than 14N within the bone, two half lives have passed and the sample is 11,460 years previous. However, if the bone is 70,000 years or older the quantity of 14C left within the bone will be too small to measure accurately.
