To argue: In favor and in against of one of the hypotheses of the origin of viruses. Introduction: Viruses are a microscopic infectious agent. These organisms are dependent on the host cells for replication. Viruses can infect both plants and animals and cause diseases. There are three hypotheses developed regarding the origin of viruses. These include the progressive hypothesis, regressive and virus-first hypothesis.

Question

Evaluate how each of the following results of scientific studies regarding mutations of the SARS-COV2 viral genome may implicate how humans can live with the virus for generations to come. Results Implication Scientific analysis of SARS-COV2 viral genomes from different countries has revealed that the virus accumulates about 2 new mutations per month. Many of these mutations have occurred due to their many battles with the immune systems of their human hosts. The vast majority of mutations have little or no effect on how the virus behaves, but scientists are keeping a watchful eye on mutations of the critical region of the viral genome: the gene encoding the spike protein. Mutations that give the virus an evolutionary advantage should be more likely to turn up repeatedly in the virus’ family tree.

Why is it a strong evolutionary hypothesis that although viruses are the structurally simplest beings they were not the first living beings?
