> shift to wetter climate makes Amazonia transition from grasslands to jungle (2k years ago)

Wait, so all those forest species living there...did they migrate from further north?

There is a lot of evidence that the rainforest is largely man made.

A quick investigation on Wikipedia suggests that there are two competing schools of thought:

- the rainforest was somewhat smaller but still intact (contra the OP)

- the rainforest was reduced to small refuges separated by grassland

This is the school of thought I've read about the most and my understanding. I never meant to imply that the entire rainforest didn't exist 2k years ago. Sorry for any confusion
