From what we know, we can confirm that Negative-sense single-stranded RNA viruses are thought to have arisen many times independently because the nucleotide sequences are not related.
<h3>What does this mean?</h3>
Nucleotide sequences are what make up the DNA of humans, or in this case, the RNA of the virus. Just as with humans, these sequences can be used to trace a lineage and see the relationships between the various kinds of viruses. These studies showed that the viruses are not related.
Therefore, since the nucleotide sequences of these viruses did not match, scientists were led to believe that Negative-sense single-stranded RNA viruses have arisen many times independently.
