Besides the order of fossils in the rocks, another method is the use phylogenetic trees.
Phylogenetic trees are used to show how all the species of particular groups of plants or animals relate to each other.
Where are the dates coming from and how is the measurement occurring?
How does the fossil record work with the geologic time scale.
What is noteworthy is that modern phylogenetic trees derive no input from stratigraphy, scientific comparisons between tree shape and stratigraphy can be used to confirm the fossil record.Chemists can measure the half-life of these elements, which is the time it takes for half of the radioactive parent element to break down into the stable daughter element.Then by comparing the two proportions of parent to daughter elements in the rock sample, and knowing the half-life, the absolute age can be calculated.Carbon Dating Carbon-14 dating is the best-known absolute dating technique.This is the one preferred by archaeologists prefer to use.
