The wealth of DNA sequence data available in public databases has revolutionized the way we identify and classify individual species and decipher how new species evolve.. All the differences between extant species are the result of the evolutionary process of genome evolution and DNA base substitution from ancestral species. This process includes the changes that accumulate due to natural selection and is the cause of phenotypic changes. Therefore, building and analysing phylogenies from DNA sequences is integral to most fields of biology, including evolution and ecology, but also molecular biology, genomics and molecular medicine.
