The world is witnessing a major pandemic caused by the 2019 novel coronavirus (2019 nCoV). Efforts are undergoing in order to identify the phylogeny of this elusive virus. It turned out that 2019 nCoV is closely related to two viruses found in bats. Similar to their distant cousins, SARS CoV and MERS CoV, 2019-CoV evolved from bats due to their large genome and greater genetic diversity. Such genetic diversity enables coronaviruses to mutate and form new species that frequently surface among the human population. Developing vaccine and predicting mutation trends in coronaviruses along with surveillance systems are proven pivotal in controlling current and future outbreaks.
