This week, I'm going to discuss the Red Queen Hypothesis, which sounds intimidating but is actually rather straightforward. Not only is it an evolutionary theory, but it's also a reminder that biologists really like finding obscure reasons to name things...

Happy Darwin Day! On the anniversary of Darwin’s birthday on 12th February 1809, I thought it would be fun to release a special episode covering some aspect of Darwin’s life or theories. Today, we’re going to discuss the health of Darwin’s children and of Darwin’s immediate family.
This week, I’m going to do something a little different and talk through a process we hear a lot about, but which isn’t often discussed as a process outside biology classrooms very much- evolution. This episode will be a little different from my usual, as it’s mainly going to be me talking rather than drawing on sources. Instead, this discussion is going to be based on my biological education so far.
Apoptosis is the phenomenon by which cells commit suicide in an orderly and programmed fashion. But why is it important? And what happens if it goes wrong? Today, we're just going to introduce the topic briefly and give some examples of why it is biologically useful.

Eye colour is one of the first examples of genetic inheritance talked about in schools across the country. But what is it that these genes really do? What causes eye colour from a functional perspective? As we'll see on the podcast today, it's all to do with the pigment melanin...

Assortative mating is essentially the recognition that theory isn’t always perfect and that, however desperately biologists might want some simplicity in the world, organisms don’t just encounter each other like gas molecules- it’s not a random process. In fact, it can even give evolution a helping hand…

Hi everyone, Vince here with a quick update- the podcast now has an accompanying website! From now on, you can head to 'www.biopedia.co.uk' to access all our episodes, as well as a blog featuring some extra content. Thank you all for continuing to listen to the show and I'm excited to add new content!
The adaptive landscape is an important method for biologists, ecologists, and geneticists to visualise the process of evolution. But what is it, and how does it work? This week, we’re going to discuss what the adaptive landscape actually is, so while there are going to be some sources listed, there's also a bit of general discussion as well.

Bonus episode! In the main episode on Sunday, I briefly mentioned NRAMP1, a mutation in which can influence how susceptible someone is to the leprosy bacterium, Mycobacterium leprae. But what exactly is the NRAMP1 protein and why is it important?

Happy new year! In our inaugural episode of 2021, we’re going to go back to the 1100s and focus on the famous case of the Leper King Baldwin IV, who ruled as king of Jerusalem from 1174 to 1185. What exactly is leprosy, and what causes it? We’ll use the test case of Baldwin as an opening to talking a bit about the bug Mycobacterium leprae and how exactly leprosy works.
