DNA analysis is one of the newer and most reliable methods of observing evolutionary relationships. Techniques such as gene mapping and DNA sequencing is used to see the genetic relationship between species.
The comparison of DNA is another strong source of evidence that organisms evolve over time.
The discovery of DNA and molecular biology complete this scientific edifice. Since the biology of evolution is integrated into all disciplines of biology and, in parallel with its development, contributes as well to trace the evolutionary history of the living. More recently, the study of evolution has benefited from the development of computer science and advances in molecular biology, notably genome sequencing, which allows the development of phylogeny by a very large amount of data.
