Who is going to win that?
************************
As a typical RNA virus, the average evolutionary rate or coronaviruses is roughly 10–⁴ nucleotide substitutions per site per year,1 with mutations arising during every replication cycle. It is, therefore, striking that the sequences of 2019-nCoV from different patients described here were almost identical, with greater than 99·9% sequence identity.
This finding suggests that 2019-nCoV originated from one source within a very short period and was detected relatively rapidly. However, as the virus transmits to more individuals,constant surveillance of mutations arising is needed.

Pompeo says he has some evidence....and he’s apparently not sharing it with Fauci. And that’s a good thing. Fauci seems to only want to contradict Pompeo with his “guess”.
