The bottom line of all life is the DNA... Previously, we compared fossils and created evolutionary trees on the basis of structure and similarity. However, this can just be a co-incidence.
Now we can compare molecular data, DNA and protein sequences and obtain the similarity and thereby predict, why our brothers in the evolutionary tree are different than us.

Molecular Clocks- are models that use mutation rates to measure evolutionary time.
Molecular evidence can prove or disprove some fylogenetic relations between organisms that were previously based on morphologic aspects or ecologic aspects.

Paleontology, genetics, molecular biology, taxonomy, evolutionary development and comparative anatomy, just to name a few.
Works on studies of genetics, phylogenetics, cladistics, evolutionary theory and experimentation, population genetics, systematics and molecular evolution, to name a few fields a evolutionary biologists works in.

The evolutionary molecular biologist and his group studies the evolutionary pathways needed to establish life on earth and was in his later years an exobiologist for NASA
Kimura (1968) • The vast majority of evolutionary changes at the molecular level are caused by random drift of selectively neutral mutants (not affecting fitness) ! The Molecular Clock.
