I imagine this has been around for a while, but my class is just starting its inheritance unit and the Biologists’s Mother’s Day Song recently came to my attention. I know it’s not even close to Mother’s Day, but the video doesn’t mention that Hallmark Holiday at all. The singer just makes the point (while addressing his mother in song) that “Slightly more than half of everything I am is thanks to you.” It goes well beyond mitochondrial DNA — in fact, for a 3.5-minute video, it covers an amazing amount of extrachromosomal inheritance. It’s cute, it’s super dorky, it’s timely (for my class), and it’s informative. What more can we ask for in a video?
