Yeah correct ! very good.

Hmm... I think, this is a sure reason, why sumatran tiger size (other morphology) is intermediate b/w mainland (malayan) and other sunda tiger clade (bali and javan).

When the ecosystems had been recovered after few millennia, another large influx of Mainland tiger managed to migrate to the western part of the Sunda Shelf. The eastern part might be relatively more isolated, thus the Sunda tigers over there were pure, whereas in the western part the Sunda tigers managed to interbreed with the Mainland tiger, therefore the hybrid tiger population like the Sumatran tigers were created.

But, I want to read the PDF (source) of this which you are referring the above info.

Or am I mistaking that, you are saying this is a theory which is not yet published? :)

Bali tiger looks like a small population of Javan tiger being isolated in the Bali island, thus in result they became even more miniaturized.

The Sumatran tiger is about the size of the Javan tiger but bigger than the Bali tiger, because the Bali tiger had been confined on an even smaller island, thus more exposed to the insular dwarfism to the extreme.

I came across these ideas from the discussion with tigerluver and Guate, and hopefully more new evidence could substantiate it. Reply
