The Pacific Gene Mystery -- Why Ancient DNA Links Australia and America

What if the deepest secret of the Amazon rainforest wasn’t in the trees, or the rivers, or the ancient soil… but inside the DNA of the people who have lived there for thousands of years?
Scientists found something that shouldn’t exist — a faint genetic echo linking Indigenous Amazonian groups to populations from Australia, Papua New Guinea, and Melanesia, across an entire ocean. No evidence of boats. No shared tools. No migration stories. Just DNA older than the rainforest itself.

This documentary breaks down one of the strangest discoveries in human history:
Why do some Amazonian tribes carry a genetic signal connected to ancient Australasian peoples?
Is it a forgotten migration? An extinct Ice Age population? Or a lost chapter in the origin of the First Americans?

This is real science, real history, and a mystery far bigger than anyone expected.
