2. Amplifying Host and Natural Reservoir

3. Currently sampled Bt-SLCoVs are too distant to be the director ancestor.

5. HB-SLCoV is closely related to Hu-SCoV; Contains direct ancestor?

6. tMRCA-Hu (estimated from S1 dataset) as a prior for
tDIV-Hu/HB Bayesian dating in ORF1 dataset

7. S1-derived tMRCA-Hu prior improved the precision of
tDIV-Hu/HB posterior of the ORF1 data set
