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.

Jerry's script remains wild. "Jerry, that's not a snake." "No, Jerry, it's not a fetish. When a scientist does it it's an area of interest."

"But the snake ancestor pulled evolution aside and said, 'I'll give an arm and a leg to be the best at it.'" I see what you did there.

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.

Ok i have to ask this : why do small lizards lift their legs up or tap them to the ground ? It's not because of heat from the ground, pretty sure of that. So why do they do this ???

Sorry the evolution theory is outdated. There are no skelets found which leads to an evolution there is no APE/HUMAN there are apes skeletons and human skeltons but nothin in between. There are no skeletons/ fosils eather who show us that this creature was a preevolution before somthin other. Proof me wrong appreciated Much love 1 family
