Examining the Fossil Record. Fossils are traces of organisms that lived in the past. When fossils are found, they are analyzed to determine the age of the fossil. The absolute age of the fossil can be determined though radiometric dating and determining the layer of rock in which the fossil was found. Older layers are found deeper within the earth than newer layers.

It includes the study of fossils to classify organisms and study interactions with each other and their environments their paleoecology. Paleontology lies on the border between biology and geology , but differs from archaeology in that it excludes the study of anatomically modern humans. It now uses techniques drawn from a wide range of sciences, including biochemistry , mathematics , and engineering.

Use of all these techniques has enabled paleontologists to discover much of the evolutionary history of life , almost all the way back to when Earth became capable of supporting life, about 3. As knowledge has increased, paleontology has developed specialised sub-divisions, some of which focus on different types of fossil organisms while others study ecology and environmental history, such as ancient climates.

Body fossils and trace fossils are the principal types of evidence about ancient life, and geochemical evidence has helped to decipher the evolution of life before there were organisms large enough to leave body fossils. Estimating the dates of these remains is essential but difficult: sometimes adjacent rock layers allow radiometric dating , which provides absolute dates that are accurate to within 0. Classifying ancient organisms is also difficult, as many do not fit well into the Linnaean taxonomy classifying living organisms, and paleontologists more often use cladistics to draw up evolutionary “family trees”.

The final quarter of the 20th century saw the development of molecular phylogenetics , which investigates how closely organisms are related by measuring the similarity of the DNA in their genomes. Molecular phylogenetics has also been used to estimate the dates when species diverged, but there is controversy about the reliability of the molecular clock on which such estimates depend. The simplest definition of “paleontology” is “the study of ancient life”.

William Whewell classified paleontology as one of the historical sciences, along with archaeology , geology , astronomy , cosmology , philology and history itself: [4] paleontology aims to describe phenomena of the past and to reconstruct their causes. For example, the discovery by Luis and Walter Alvarez of iridium , a mainly extraterrestrial metal, in the Cretaceous — Tertiary boundary layer made asteroid impact the most favored explanation for the Cretaceous—Paleogene extinction event – although debate continues about the contribution of volcanism.

A complementary approach to developing scientific knowledge, experimental science , [8] is often said [ by whom?
