00:17Now, that theory has been confirmed, with a DNA analysis of the samples revealing they are indeed 3600-year-old

00:24The researchers say they have found both cow and goat DNA amongst the samples.
00:28They say it's a type of fermented kefir cheese from the Bronze Age,
00:32with paleontologists saying this is the oldest known cheese sample ever discovered in the world.
00:38They add that this find is significant because food products are often extremely difficult to preserve,
00:43especially over thousands of years,
00:45giving researchers a rare opportunity to examine food preparation methods of ancient times.
00:50In fact, they identified the specific strain of bacteria used to produce this cheese came from Tibet,
00:55with the study's authors adding,
00:57this is an unprecedented study, allowing us to observe how a bacterium evolved over the past 3000 years.
