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.

Mainly, their skulls or head looks similar to wanhsien. (IMO) and ofcourse size is a variant. Mainly south china skull very resemblant to acutidens.

Caspian could back migrate and procreate with the archaic Wanhsien population to give the birth of the Amur tiger.
They evolved pretty recently mainly bengal. Though I find caspian similar to wanhsien (I don't know why but they look kinda similar to me ). Bengal and caspian might had some connectivity at a particular point of time (may be) (see the map). Caspain and founder wanhsien of Siberia region might had an exchange of genepool again (after their separation for some time) at some point too to give amur tiger in siberia. Those amur and wanhsien in japan might had again bred to give Japanese tiger. (see map)
Spp level hybridization occurs for almost every species when their habitats are fragmented and altered by humans. Take for example, bengal and indochinese tigers reproduced until few thousand years in their overlapping ranges of north east India.
