Phylogenetic systems

The study of the evolutionary links among distinct biological species is known as phylogenetic systems, or phylogenetics. It involves creating and analysing phylogenies—diagrams that show the evolutionary links among various species—using genomic data. These data can be used to identify closely related existing species, infer evolutionary history, and find and categorise new species. Sequences of DNA, RNA, or proteins may be included in the genetic data used, and examination of these sequences can show phylogenetic relationships. Ecology, systematics, and population genetics are just a few of the biological disciplines that employ phylogenetic systems. They can also be used to research how bacteria, viruses, and other microbes have evolved. An essential tool for comprehending the origins and variety of life is phylogenetics.
