About 5 years ago (as a post-doc), I worked at Adelaide Uni's Australian Centre for Ancient DNA (ACAD).
At that time, I held the group record for oldest aDNA isolated & amplified: 60 thousand years old from a horse tooth found in a cave in Siberia.
That 'record' has been obliterated over the last few years!
At ACAD, we were involved in Flores 'hobbit' research - we were unable to get any aDNA at all, most likely because of the hot, humid conditions (even in a cave).
So this 400,000 year-old aDNA from Spain was a great surprise & extremely impressive!
