Specimen Wren

One of my old Bio professors ran up to me today and said "Oh! I used you as an example in my 112 class yesterday!"

"Oh?"

"Yes! I said 'now Wren's hair is purple, but not because of her genetics. Can you see the difference here?' And a couple of my students were nodding vigorously and going 'Yeah!'"

"Well, thank you!"

"No, thank you!"
