Happy holidays everyone, it’s me, Katie Goldin, your host of many parasites! Today, on the second part of our two-part holiday special, we’ll be creating our own non-denominational holiday using evolutionary biology to make this magical time of year scientifically accurate! We’ll talk the biology of reindeer, and the best bacteria-filled lightshow in the world! With special guest Jamie Loftus of The Bechdel Cast.
