In the next section, we will look at how viruses have evolved over the years.

However, the clinical severity of the outbreak and how the virus will evolve cannot yet be predicted.

A virus could emerge, evolve, and move between species.

Hence, there is very good evidence this virus is quite ancient, and may well have evolved more than one time over the last 10,000,000 years.

This time, for the first time, scientists are able to watch the virus evolve.

But, he added, "That's the niche this virus has evolved into."

"On the other hand, viruses evolve and they have the capacity to adapt themselves."

Reassortment allows new viruses to evolve under both natural conditions and in artificial cultures.

New bacteria and viruses evolve, and old ones grow more resistant to treatment.

Will the virus itself evolve to become more virulent?
