When I was in graduate school my life and carreer were completely transformed by a seminar I attended at Stanford by Dr. Hamilton Smith. In the talk he discussed how TIGR was sequencing whole genomes of organisms. Here is a scan of P1 of my notes. 1/n

Was at Moss Landing for a project on sea otters. More on that later. I also took tons of pics of terns and I kept just missing them catching food. Or so I thought. I got back this afternoon and discovered this series. I never knew this was in their diet. #Birds
