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.

Phylogeny, mathematics, and other methods used to date fossils.

Biologists now have at their disposal a variety of independent means to look at the history of life.

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.Where are the dates coming from and how is the measurement occurring?How does the fossil record work with the geologic time scale. 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?
