Phylogeny of animals, plants and bacteria

Phylogeny describes a common belief among scientist across the globe that animals and plant in a community which stem from different species have common ancestral descendants. The evidence for this relationship is always incomplete as most of the species which are described are extinct. One merit of phylogeny are that it enriches our understanding on how the genomes, genes and species evolve. This enhances our understanding of not only how the consequences of this evolution are today, but also predict how they can be tomorrow or in the next generation. Note, this is not only the importance of phylogeny, but can also be applied in various places and issues in the real life. 

In real life situation, phylogeny of bacteria can help in identification of any bacterium pathogens in healthcare sector. Bacterium is one of the major causes of illness. In many cases, there are new diseases outbreak in a certain community and the pathogen is causing this conditions may still be unknown. This is where phylogeny of that specific organism or pathogens can be used to identify the organism and how it can be treated. For instance, assuming that the condition which has suddenly killed many people still has its pathogenic causation under the dark. The scientist can try and isolate the pathogen causing the disease. Postulating that the pathogen is a bacterium, phylogeny can be used to trace back to the species from which this pathogen originated be revealed (Phylogeny). After identification of the species, phylogeny can again reveal the mode of transmission of the species. This is enough information which can be used in the public healthcare sector to caution people on how to handle the outbreak of the condition. Based on the information provided by phylogeny, the modes of transmission can be known and deal with the pathogen would be much easier.
