Fossil record radiometric dating
The majority of test cases show good agreement, so the fossil record accordingly relates the same story as the molecules enclosed in living organisms.Techniques used for Absolute Dating All of this gets us to one of the most important physical techniques, radioactive Dating.It was all clear when in 1859 Charles Darwin published his "On the Origin of Species".The 'progress' shown by the fossils was a documentation of the grand pattern of evolution through long spans of time.At the oldest, or deepest layer of rock there was no record of fossils, but then they noticed that simple sea creatures were found at the next higher level, then more complex ones like fishes at the next higher level and so on.
The Fossils Sequence Record It was the study of rock layers in England near the beginning of the 19th century that lead to the study of paleontology and from there to the study of fossils.
Any attempt to make a claim about evolution always comes back at some point to the geologic time scale.
But if you are going to be looking at time scales that are that old how do you get the dates?
Carbon dating in geology may be relative or absolute.
One does relative dating by observing fossils sequences using the stratigraphical method.
