Ancient poo gives clues to human impact on environment

US scientists say they can track early human movements by analysing molecules in ancient faecal matter.

Researchers were able to use prehistoric poo to establish the presence and size of a population dating back over 7,000 years.

They argue the method could be used to distinguish human from natural impacts on past environments.

Details have been published in the journal Proceedings of the National Academy of Sciences.

The bit about having a strong signal made me smile - good article though.

"Now researchers at the University of Massachusetts at Amherst say they have discovered a much more accurate marker that produces a "strong human signal.""
