TMRCA relies on accurate information about when specific strains were identified.
There is ample reason to believe Chinese authorities lied about when they observed specific strains.
- ImaCake 6y agoCan you provide some evidence to back up your claim here? The TMRCA calculations would have ample information to provide a statistically accurate date without a single Chinese genome at this point. Those early Chinese genomes merely act as a validation that the genetic clock is "ticking" how the model(s) estimates that it did.

- pstrateman 6y agoThe TMRCA calculations need to know approximately how many people were infected to calculate the time. Mutation rate is essentially based on how many people the virus passes between not really time. So if China is lying about the number of infections early on (or even simply doesn't know the true number) then the calculated time of first infection would be off.
