S2E4: Colors of the Rainbow


Hey y’all! Welcome to episode four, Colors of the Rainbow! Today’s podcast is brought to you by Sarah Haerle, Sara Bidarian and Akira Momozono where we will discuss the evolution of color vision in species ranging from fish to homo sapiens.


First, we will discuss a few facts about color blindness and the ways in which color vision actually functions. We will then be joined by several special guests who will provide insight into their outlook on the world! Through listening, you will gain insights into the unique experiences of organisms such as the mantis shrimp, horse, bat, and primate. Listeners will also discover the interesting convergence of color pigments in humans and fish… who knew!


We will answer some of your most pressing questions…
  • Can crustaceans distinguish colors in a rainbow?
  • Do colorblind humans see in the same way as horses do?
  • Do bats see color even though they live in the dark?
  • How and why did trichromatic vision evolve?
  • Are humans more closely related to fish than we thought?

Join us as we attempt to see life (and colors) from the perspective of our guests!

E7: Testudines Test for Love

Hey everyone! On today’s episode of the Entangled Bank Podcast, Bailee and Lexie are checking in to help our special guest, Lonely George, find his bachelorette on “Testudines Test for Love.” Join us while we dive into looking at five different species, which are our candidates, and compare physical attributes such as the evolution of shell size/strength, ecological relationships, geographical location, and other defining characteristic to aid us in our search for George’s true love. Will Lonely George find his bachelorette and live happily ever after? Sources: Shell Evolution Taxonomy, T. 2016. Size, Shape , and Stress in Tortoise Shell Evolution 72:309–317.

S2E2: Evolution of Quadrupeds

Hello everyone! Welcome back to the Entangled Bank podcast! This week’s topic explores the evolution of quadrupeds. Nikki, Sarah, and Jamie will be discussing how quadrupeds began in the water, transitioned to land, and then returned back to the water. So turn up that volume and get ready to learn about the development of limbs! As mentioned above, our story begins in the water. Paired fins (a fin on each side of the body) actually began as a single, pelvic pair before becoming the double paired fins we’re familiar with today. This development is a result of Hox gene expression. According to  Edwards (1989), there are two theories why paired fins evolved: structural use and functional use. After much research and observation, Edwards found that functionality (movement, feeding, defense, etc.) is the most likely reason. Fins are not the only type of aquatic limb; there are non-paired limbs as well, such as octopus and sea stars. Some animals felt it was time to m...

S2E6: Evolution of Hands

Welcome to GBP, the Great Biological Podcast! Join your esteemed hosts Garrison, Bo, and Pranav this week as we welcome a curious young scientist, Nicky J, onto our podcast to discuss something that many people take for granted: their thumbs! Listen along as we dive into the evolution of the modern human’s thumb and hand. Not only will we discuss how our hands evolved from a primate’s hand, but also just how unique our hands and thumbs have become and all the fun things we can do with them!   We talk to Nicky J about how the human thumb was first seen long ago with the primate Notharctus tenebrosus. From there the primate hand continue to evolve over hundreds of thousands of years until we saw the Middle Pleistocene fossil from Kenya resembling the modern human hand with a similar third metacarpal and thumb physiology. Likewise, we continued to see thumb muscles evolve from primates with different thumb muscles connecting to the forearm being slightly similar to a primate’s but...
