the 'fossil' tracks counted) viz., exposes the sample to a known number of low energy (thermal)neutrons which induce fission of a small fraction of the uranium atoms in the sample.
The sample is immersed in the proper chemical reagent, which allows rapid attack of the narrow regions of damage and slower dissolution of the adjacent unchanged material.
According to the Dictionary of Anthropology, the word chronology means the science of computing dates or treaties showing arrangement of events with dates.
The density of track depends on the uranium content as well as the age of the sample (i.e.They are engaged in defining the stages of hominid evolution and their artifactual record, and the assignment of a chronology to these stages.Chronology is the science of measuring time and ordering of the things in time.Amino Acid Racemisation, a method of absolute dating applied to human fossils is developed very recently.This is based on the fact that all living organisms have L-amino acid in their protein and after death, and over a long period of time all the L-amino acids except glycine undergo change called racemisation and became non protein D-amino acid.
The emergence of man through the process of biological and cultural evolution is a story of long span of time.
