When they talk about "tropical home", or "tropical rainforrest" they are making the assumption that the weather was the same 48.000 years ago, which was not.
The last glacial period goes from 120,000 and 11,500 years ago, so the weather in Sri Lanka at the time was probably like Germany today, even while being "tropical".
Using the world "tropical" will confuse most people, as they link the current word meaning with the one in the past, degrading it.

When it comes to the paleoclimate of current subtropical/tropical regions during glacial maxima, the question is how the 120 meter lower sea levels impacted the local hydrology. If the endemic species continued throughout one or more glacial maxima (e.g. gorillas, chimps, bonobos in the Congo basin, orangutans on Borneo/Sumatra) then the adapted ecosystem probably remained constant. The climate history of Sri Lanka should be well documented. My intuition is that tropical rainforest is a fine assumption.
- s1artibartfast 6y ago>the weather in Sri Lanka at the time was probably like Germany today, even while being "tropical" This seems like a pretty strong claim given the roughly equatorial location. Do you have expertise in the field or a source?
