Results from absolute dating methods will not be available from a laboratory for several weeks, and the paleontologist needs the information.

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.

While true, fossils are buried with plenty of clues that allow us to reconstruct their history. In , in Ethiopia’s Afar region, our research team discovered a rare fossil jawbone belonging to our genus, Homo. To solve the mystery of when this human ancestor lived on Earth, we looked to nearby volcanic ash layers for answers.

Working in this part of Ethiopia is quite the adventure. It is a region where 90 degrees Fahrenheit seems cool, dust is a given, water is not, and a normal daily commute includes racing ostriches and braking for camels as we forge paths through the desert. But, this barren and hostile landscape is one of the most important locations in the world for studying when and how early humans began walking upright, using tools and adapting to their changing environments.

Early on, before we had more precise means to date fossils, geologists and paleontologists relied on relative dating methods. They looked at the position of sedimentary rocks to determine order. Imagine your laundry basket—the dirty clothes you wore last weekend sit at the bottom, but today’s rest on top of the pile. The concept for sedimentary rocks is the same. Older rocks are on the bottom, younger ones are on top.
