There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

Freak Felids - A Discussion of History's Largest Felines

Regarding Driscoll's estimate, take it with a grain of salt. Only one study has attempted molecular dating of the tiger genome. 

Take mitochondrial Eve for example (https://en.wikipedia.org/wiki/Mitochondrial_Eve), one date range is 99-148 kya and the other 160 kya. Molecular DNA dating is not easy to pinpoint with great certainty. Confidence intervals don't necessarily prove the estimate either, as in the end, the confidence interval is still the product of the data. 

The Manchurian fossils have fallen through the cracks, thus hypotheses are the only publishable options of when tigers arrived there. Remember, "the hypothesis that tiger population structure reflects recent (less than 10,000 y ago), human-induced population fragmentation and random lineage loss from a single panmictic population is not supported by the strong geographical partitioning of the mitochondrial lineages or by differences in measures of nucleotide diversity within each subspecies"(Luo et al. 2004). Therefore, if tigers got to Manchuria earlier than 10 kya, it is probable they would have started evolving from the Wahsien form soon after, especially those populations away from the Wahnsien-Amur boundary.
