Complete observable evolution can be witnessed at the genetic level. While evolution undergoes the process called mutations, the virus mutation rate is extremely high which happens every time through bioengineering, cross-species infections, interactions with the host and the environment, and other natural and artificial factors. In natural selection, it says that large size of virus population may favor the mutation of predominant size of the virus population to adapt to the host and its counter-measures, totally wiping out other viruses with random genetic drift or those with deleterious alleles, these signify the viruses might have evolved into benign pathogens without the lethal ones. However, when the viral population is small, random mutations may obliterate the adaptive alleles and ugh! they may rise to a high frequency in the population and destroy their hosts and together become short-lived directly opposing the viruses' own survival - exterminating their own species by failing to adapt to their environment.
The 2019 nCov is new and is causing the people's panic buying of cost-inflated face masks while the scientific community is yet to find the cure or vaccine. The outbreak's control remains to be isolation and excretion amidst the claim of asymptomatic spread with maximum days of 14 before discovery and possible isolation. With the aforementioned, the 2019 nCov population is being restrained to small size avoiding the possible large collateral damage in allowing them to transform into tolerable disease agents with larger population. It remains that human conscience and morality will always protect humanity at the most appropriate level by being dominantly raised above scientific novelty and material wealth gained through exploitation of the academia and economy 😱😧
