And it is quite interesting that the modern Amur tiger got its ancestry traced back to the western part of Asia.

They must derive from a group of Wanhsien tiger isolated in the West-Central Asia during the last glacial period.

 

Here is the image of Driscoll et al. (2009) about the invasion of the tigers in the Caspian region and the re-invasion of Central Asia (correctly know as Siberia) and up to the far east.

The correct pats were "C" and "D". Interestingly, this show that at least about 200 years ago, the term "Siberia tiger" was correct after all.

Genetic studies of Dr Shu-Jin Luo and her team suggest that all tiger populations were almost extinct about 75,000-108,000 years ago, and only a single small population in the north of Indochina-South of China survived and gives origin to all the modern tiger populations. This suggest that only the southern population of Wanhsien tigers survived the terrible winter that caused the clouds of dust provoked by the Toba eruption, while all the others died, probably from starvation as the population of ungulates also disappeared as the plants died. So, modern Amur tigers are the newest population, descendent from the Caspian tigers and adapted to a new prey base, like the large wild boars (that formed the angular stone in the Caspian tiger feeding) and developed larger skulls with larger sagital crest and larger canines and a much robust bodies. Bengal tigers also developed similar characteristics, but retained a relative slender cranial form, in comparison with those from North-Central Asia.

This topic is only about lions, and I will not like to mix themes. Greetings GrizzlyClaws. [img]images/smilies/tongue.gif[/img]
