Firstly, many thanks to those who have replied so far...
We actually now have a reference to a paper in AUK on DNA extraction "from
a single feather" (alas, our library doesnt stock AUK so the search goes on).
Any further info on the "guy in Ottawa" (8>) would be much appreciated, if
he is in fact extracting DNA.
On a wider note- what other odd DNA sources have been used out there?
I guess subfossil bones, stuff from pyramids etc... Anything wierder?
Just a thought.
