Dr. Kurt Schwenk
It was a pretty incredible gift to be able to work with Kurt on this episode. His work spans decades and it took multiple tries to understand it in a way that could be put together in a narrative. I am very grateful for all of his time, warmth and generosity. I had to leave many, many wonderful pieces of research and factoids out due to time constraints but I would urge any of you that are interested to dive deeper into his work.
His colleagues Dr. William G. Ryerson, Ms. Amanda E. Hewes and
Ms. Sara Horwitz contributed a great deal to some of the research that I mentioned.
Dr. Margaret Rubega ( deserves thanks for introducing me to Kurt in the first place.

Jobs that no-one wants #5438: product manager at Evolution, Inc. "Are you actually shitting me with this? All our users said they needed some way of cleaning and protecting their eyeballs. So we gave them Eyelid v1.0. Now this one user, Gordon effing Gecko, says "naah, fam - I don't want eyelids. I wanna lick my eyeballs clean." Sure, pal - we'll put it in the backlog.

have you ever thought about making a video about flies? Or drosophila melanogaster to be specific. I'd recommend looking into the courtship behavior and all the messed up mutations there are (eyes on leg, leg for eyes, etc.). I study biology and we experimented with them, no mutations though, just behavior.
